FIRE AND BURN HAZARD

Failure to follow these instructions will result in death or serious injury.

Failure to follow these instructions can result in minor or moderate injury.

• Do not cover or obstruct the air intake vent openings and/or install in a zero-clearance compartment.

• Do not use transformerless battery chargers in conjunction with the inverter/charger due to overheating.

EXPLOSION HAZARD

• Charge only properly rated (such as two 12 V in series for a 24 V battery bank) lead-acid (GEL, AGM, Flooded, or lead-calcium) rechargeable batteries because other battery types may explode.

• Do not work in the vicinity of lead-acid batteries. Batteries generate explosive gases during normal operation. See note #1.

• Do not install and/or operate in compartments containing flammable materials or in locations that require ignition-protected equipment. See notes #2 and #3.

NOTES:

1. Follow these instructions and those published by the battery manufacturer and the manufacturer of any equipment you intend to use in the vicinity of the battery. Re view cautionary markings on these products and on the engine.

2. This inverter/charger contains components which tend to produce arcs or sparks.

3. Locations include any space containing gasoline-powered machinery, fuel tanks, as well as joints, fittings, or other connections between components of the fuel system.

4. Freedom SW 230V inverter/charger products are designed for deep cycle lead-acid batteries only. Charging lithium-ion batteries are currently not supported and doing so is an explosion hazard. Lithium-ion battery cells are individually monitored for voltage and temperature. The Freedom SW 230V does not support this individual cell monitoring on lithium-ion batteries.

PHYSICAL INJURY HAZARD

This Freedom SW 230V Inverter/Charger is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

Precautions When Working With Batteries

Failure to follow these instructions can result in death or serious injury.

IMPORTANT:

personnel knowledgeable about batteries to ensure compliance with battery handling and maintenance safety precautions.

BURN FROM HIGH SHORT-CIRCUIT CURRENT, FIRE AND EXPLOSION FROM VENTED GASES HAZARDS

• Always wear proper, non-absorbent gloves, complete eye protection, and clothing protection. Avoid touching your eyes and wiping your forehead while working near batteries. See note #4.

• Remove all personal metal items, like rings, bracelets, and watches when working with batteries. See notes #5 and #6 below.

• Never smoke or allow a spark or flame near the engine or batteries.

• Never charge a frozen battery.

NOTES:

1. Mount and place the Freedom SW 230V Inverter/Charger unit away from batteries in a well ventilated compartment.

2. Always have someone within range of your voice or close enough to come to your aid when you work near a lead-acid battery.

3. Always have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.

Battery work and maintenance must be done by qualified

4. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters your eye, immediately flood it with running cold water for at least twenty minutes and get medical attention immediately.

5. Use extra caution to reduce the risk or dropping a metal tool on the battery. It could spark or short circ uit the battery or other electrical parts and could cause an explosion.

6. Batteries can produce a short circuit current high enough to weld a ring or metal bracelet or the like to the battery terminal, causing a severe burn.

7. When removing a battery, always remove the negative termina l from the battery first for systems with grounded negative. If it is grounded positive, remove the positive terminal first. Make sure all loads connected to the battery and all accessories are off so you don’t cause an arc.

Precautions When Preparing to Charge

Failure to follow these instructions can result in death or serious injury.

Failure to follow these instructions can damage the unit and/or damage other equipment.

Precautions When Placing the Inverter/Charger

EXPOSURE TO CHEMICALS AND GASES HAZARD

• Make sure the area around the battery is well ventilated.

• Make sure the voltage of the batteries matches the output voltage of the inverter/charger.

• Be careful to keep corrosion from coming into contact with your eyes and skin when cleaning battery terminals.

NOTES:

• Study and follow all of the battery manufacturer's specific precautions, such as removing or not removing cell caps while charging, whether equalization is acceptable for your battery, and recommended rates of charge.

• For flooded non-sealed batteries, add distilled water in each cell until battery acid reaches the level specified by the battery manufacturer. This helps to purge excessive gas from cells. Do not overfill. For a battery without removable cell caps, carefully follow manufacturer's instructions.

RISK OF DAMAGE TO THE INVERTER/CHARGER

• Never allow battery acid to drip on the inverter/charger when reading gravity, or filling battery.

• Never place the Freedom SW 230V Inverter/Charger unit directly above batteries; gases from a battery will corrode and damage the inverter/charger.

Planning the Installation

This section provides information to help you plan for a basic installation of the Freedom SW 230V.

As your system configuration is determined, record the details in “Information About Your System” in the Freedom SW 230V Sine

Wave Inverter/Charger Owner’s Guide.

Two Key Performance Factors

Two key factors in particular will have a major impact on system performance.

Size and Length of DC Cables

To select the appropriate size and length of DC cables, see “DC Cabling” on page 13.

The DC cables should be as short as possible and large enough to handle the required current, in accordance with the electrical codes or regulations applicable to your installation. If there are long battery cables which are in excess of 3 meters each and not of sufficient size, the voltage drop across the cables will have a negative impact on overall system performance.

Planning Preparations

AC Components

NOTE: Unless otherwise referenced specifically by product name,

the components refer to all models of Freedom SW inverter/ chargers.

AC Input

AC input can be supplied from a single-phase 230-volt 50-Hz AC source such as the utility grid (power company), a generator, or the output of a transfer switch.

AC Output

The output voltage on Freedom SW inverter/chargers is 230 volts AC. The Freedom SW 2524-2 30 and Freedom SW 3524230 models have a Single Input and Single Output line (SI-SO) configuration.

AC Loads

The Freedom SW 230V is intended to power loads consisting of 230 volts/50 Hz AC appliances.

In Invert mode, the Freedom SW 230V provides 230 volts/50 Hz AC to loads connected to Line out. In AC Bypass mode, the source connected to the AC input is passed through to the load. Only 230 volts/50 Hz AC appliances can be connected to the Freedom SW 230V output.

AC Disconnect and Over-Current Protection Device

To meet mobile electrical code requirements, and to protect system wiring, the AC inputs and outputs of the inverter/charger must be provided with overcurrent protection on both the AC input and output. This protection may be a circuit breaker or a fuse with a disconnect device (for simplicity the following refers to breakers). Refer to your applicable installation codes and the following requirements:

AC Input Protection

The breaker protecting the AC input of the Freedom SW 230V must be approved for use on 230 volts AC branch circuit. The breaker must be rated no more than 30 amps maximum.

AC Output Protection

The breaker between the Freedom SW 230V AC output and the AC loads must be rated to protect the AC output wire size used. If the AC output wiring is based on the full 30-amp pass-through rating, then a 30-amp output breaker is acceptable. If the AC output wiring is smaller, then the breaker size will have to be smaller as well, in accordance with applicable electrical installation codes.

10 Freedom SW 230V Installation Guide

GFCI Requirements

Planning Preparations

Distribution Panels

A GFCI (ground fault circuit interrupter) is a device that deenergizes a circuit when a current to ground exceeds a specified value that is less than that required to open the circuit breaker. GFCIs are intended to protect people from electric shocks and are usually required in wet or damp locations.

Installation in recreational vehicles may require GFCI protection of certain branch circuits. Consult all applicable codes.

Disconnect Devices

Each system requires a method of disconnecting the AC circuits. If the overcurrent protection device is a circuit breaker, it will also serve as the disconnect. If fuses are used, separate AC disconnect switches will be needed between the source and the fuses.

Some systems incorporate distribution panels both ahead of the inverter/charger (the AC source panel) and between the inverter/ charger and the loads (the AC load panel). The AC source panel includes a main circuit breaker, which serves as overcurrent protection for the panel. Additional circuit breakers serve individual circuits, one of which serves the inverter/charger.

AC Wiring

Definition AC wiring includes input wiring (all the wires and connectors between the AC source and the inverter/charger input) and output wiring (all the wires between the inverter/charger and the AC load panels, circuit breakers, and loads).

Type The type of wiring required varies according to the electrical codes or regulations applicable to your installation. For RV applications, this may be solid wire in multi-conductor cables, but stranded wire is required if single conductors are used. All wiring must be rated 75 °C or higher. In Australia, all wiring must be rated 90 °C or higher.

Size of AC Input Wiring W ire size must be coordinated with the overcurrent protection provided ahead of the wire involved, in accordance with the electrical codes or regulations applicable to your installation. Therefore, the wiring used between the AC input circuit breaker and the inverter/charger input must be sized to match the input breaker rating.

This current may be determined by the 15-amp (Freedom SW 3524-230) and 11-amp (Freedom SW 2524-230) maximum inverter current, or by the bypass current, which is determined by the overcurrent protection provided ahead of the Freedom SW 230V.

Size of Wiring Downstream of the AC Output Breaker The wiring used between the AC output breaker and your loads must be sized in accordance with the rating of the output breaker.

12 Freedom SW 230V Installation Guide

DC Components

Failure to follow these instructions can result in death or serious injury.

Batteries

The Freedom SW 230V system requires a 24-volt, lead-acid deepcycle battery or group of batteries to provide the DC current that the inverter/charger converts to AC power. The battery may be a flooded, gel, or AGM type.

See “Battery Information” on page 52 for information on:

Installing the Inverter/Charger

Failure to follow these instructions will result in death or serious injury.

Failure to follow these instructions can result in minor or moderate injury.

Step 1: Choosing a Location for the Inverter/Charger

The inverter should only be installed in a location that meets the following requirements:

FIRE AND EXPLOSION HAZARD

This equipment contains components that could produce arcs or sparks. To reduce the risk of fire or explosion, do not install this equipment in compartments containing batteries or flammable materials, or in locations that require ignition-protected equipment. This includes any space containing gasoline-powered machinery, fuel tanks, or joints, fittings, or other connections between components of the fuel system.

HEAT HAZARD

Do not cover or obstruct the ventilation openings. Do not install this equipment in a compartment with limited airflow. Overheating may result.

18 Freedom SW 230V Installation Guide

Ventilated Do not operate the inverter/charger in a closed-in

area or restrict ventilation in any way. The inverter/ charger requires air circulation to maintain optimum operating temperature and provide best performance. If the unit has inadequate ventilation, it may shut down due to overheating. The air vented through the openings should also have a path to circulate away from the inverter/ charger.

Dry Do not allow water or other fluids to drip or splash

on the inverter/charger. Do not expose to rain, snow or water. Use an optional inverter drip shield (PN: 808-9004) for marine installations.

Cool Normal air temperature should be between

0 °C and 60 °C—the cooler the better within this range.

Clearance Allow as much space around the inverter/charger as

possible. It is recommended that other objects and surfaces be at least 76 mm away from the ventilation openings for best performance.

Installing the Inverter/Charger

Safe Locate the inverter/charger aw ay from batte ry in a

separate well ventilated compartment. Do not install the inverter/charger in any comp a r tme nt containing flammable gases or liquids like gasoline.

Close to battery compartment

Protected from battery acid and gases

The length and size of your DC cables will affect performance. Use the DC cables recommended in Ta ble 2 on page 13. The unit should not be installed in the battery compartment due to the possible presence of explosive hydrogen gas from the batteries.

Never place the inverter/charger directly above the batteries—gases from battery will corrode and damage the inverter/charger. If the inverter/charger is installed in a compartment above the batteries, make sure there is a solid, gas-impermeable wall dividing the two compartments. However, flooded or wet cell batteries produce flammable gases that can potentially be ignited and therefore a safety hazard. If the batteries are sealed (no caps to add water), then the Freedom SW 230V can be mounted above the batteries if so desired (a position outlined in the manual).

Never allow battery acid to drip on the inverter/ charger or its wiring when filling the batteries or reading their specific gravity.

Orientation To meet regulatory requirements, the Freedom SW

230V must be mounted in one of the approved mounting orientations. See Figure 5 on page 21.

Failure to follow these instructions will result in death or serious injury.

Step 3: Connecting the AC Input and AC Output Wires

recommended to use a separate inverter load panel to distribute power to inverter loads. All wiring to this panel must be through the

FIRE, ELECTRICAL SHOCK, AND ENERGY HAZARDS

Make sure wiring being connected to the inverter/charger is de-energized by a breaker or switch upstream. Lockout/Tagout is a recommended practice by many electrical contractors. Always lockout and tag

disconnect devices before making connections. All wiring must be done in accordance with local and national electrical wiring codes.

General AC Wiring Considerations

AC and DC Wiring Separation Do not mix AC and DC wiring in the same conduit or panel. Consult the applicable installation code for details about DC wiring and AC wiring in vicinity to each other.

AC Input and Output Isolation The AC input and output circuits of this inverter/charger are isolated from each other when in invert mode to ensure safe operation. This isolation must be maintained in the installation, by being sure not to connect AC input and output wiring to a common point. For example, do not route the AC input and output neutrals to a common neutral bus. It is highly

inverter/charger and none to the main panel upstream of the inverter/charger.

IMPORTANT: W iring the output inverter to back to the main panel could result in ground bonding to occur in multiple locations in contravention of applicable wiring codes and may result in nuisance tripping of Ground fault protection equipment. All wiring must be performed by a qualified electrician.

AC Wiring Compartment For your reference, the AC wiring compartment is shown in Figure 6 on page 25.

AC Knockouts There are two dual 1.0" (Ø34.6mm) and 3/4" (Ø28.3mm) trade-size knockouts on the side panel for AC wiring. Use the same trade size of strain relief as the trade size of the knockout(s) you are using.

AC Wiring Terminals The AC wiring terminals accept cables of a specific size. See “AC Wiring” on page 11 for required sizes.

Guidelines for Routing the DC Cables

Failure to follow these instructions can result in minor or moderate injury.

Follow these guidelines to ensure maximum performance.

ELECTRICAL SHOCK AND FIRE HAZARD

Route the cables away from sharp edges that might damage the insulation. A void sharp bends in the cable.

• Do not attempt to use the chassis in place of the battery negative connection for grounding. The inverter requires a reliable return path directly to the battery.

• To reduce the chance of radio frequency interference, keep the positive and negative cables close together—ideally, held together by straps, loom, or insulated clamps at regular intervals.

• To ensure maximum performance from the inverter/charger, do not route your DC cables through a DC distribution panel, battery isolator, or other device that will cause additional voltage drops. The exception is the DC fuse and Disconnect or the DC circuit breaker which is required at the battery to protect the DC wiring.

• To help avoid damage caused by reverse polarity battery connection, it is a good idea to mark each end of each cable to identify it as a positive (red) or negative (black) cable before routing the wiring.

Installing the Inverter/Charger

Installing the Inverter/Charger

Failure to follow these instructions can result in death or serious injury.

Failure to follow these instructions can damage the unit and/or damage other equipment.

Connecting the DC Cables to the Inverter/Charger

FIRE HAZARD

Use only appropriately sized copper cable. Loose connections, improper connections, and under-rated cables will overheat. Make sure that the supplied bolts on the inverter/charger are tightened to a torque of 20.4–

21.7 Nm. Torque all other connections to the manufacturer’s specifications. Make sure the DC cable, washers, and bolt are assembled in the order shown in Figure 7.

EQUIPMENT DAMAGE DUE TO REVERSE POLARITY

Before making the final DC connection or closing the DC breaker or disconnect, check cable polarity at both the battery and the inverter/ charger. Positive (+) must be connected to positive (+). Negative (–) must be connected to negative (–).

To connect the DC cables:

1. Route the DC cables from the battery bank to the inverter/ charger. Observe the “Guidelines for Routing the DC Cables” on page 29.

2. Install a DC fuse and disconnect switch or a DC circuit breaker between the inverter/charger and the battery. It must be installed in the positive side of the DC circuit, as close as possible to the battery.

This protects your battery and wiring in case of accidental shorting. See Table 3 on page 14 for required fuse or breaker size.

3. Open the DC disconnect switch or turn off the DC circuit breaker.

4. Connect one connector on the POSITIVE (+) cable to the POSITIVE DC terminal on the inverter/charger, as shown in Figure 7. The connector goes on first, then the lock washer and bolt.

5. Connect the other connector to the POSITIVE (+) terminal on the fuse or breaker. Observe polarity carefully while completing the installation.

Use a wrench to tighten the bolt to a torque of 20.4–21.7 Nm at the inverter/charger end. Observe the fuse holder or breaker manufacturer’s recommendation at the other end.

At this point all devices in the system will be automatically placed in standby mode. All three LEDs on the inverter to be configured will start flashing.

For both units to operate in stacked configurations, a Master and Slave have to be assigned. The default out-of-box configuration for all Freedom SW 230V inverter/chargers is Master which causes a conflict the first time the system is powered up. The installer will need to change configuration on one of the inverter/chargers to

Slave mode.

NOTES:

The only situation in which the Slave may shut down the Master inverter is during fault conditions such as high or low battery voltage, overcurrent, or over-temperature conditions. Both inverters will auto reset after a fault condition has been cleared. The exception is that an overcurrent condition will generate a shutdown for both inverters that will require a manual restart of the system.

Stacking Features

Failure to follow these instructions will result in death or serious injury.

Search Mode Operation in Parallel Stacking

When two inverter/chargers are stacked for parallel operation, search mode behavior on the Slave unit is modified and is dependent on how much total load is on the system.

Disabling Search Mode on the Master Unit

In parallel stacking, search mode on the Master unit will not function properly. When the Master sends out a load search pulse, a small current also flows into the output of the Slave unit since the two outputs are in parallel. This Master unit falsely detects a load causing erratic search mode operation. For this reason, it is highly recommended to disable search mode on the Master unit in a parallel stacking system.

the two will share the load equally. Should the load on the Master drop below 20% of rated load (700 watts for Freedom SW 3524-

230), the Slave unit disengages and returns to a waiting state. Search mode disabled The Slave unit operates continuously

along with the Master unit and shares the load.

Wiring Schematic

NOTE: Please refer to the Stacking Configuration sheet that shows

the wiring schematic employed between two Freedom SW 230V inverter/chargers that are stacked in parallel.

IMPORTANT: Follow the same guidelines in “Installing the Inverter/Charger” on page 17 when choosing cables and/or wires for AC and DC connections.

Setting Search Mode on the Slave Unit

The Slave unit will behave in one of two ways depending on whether its search mode is enabled or disabled.

Search mode enabled This is the recommended mode for parallel stacking and it helps minimize battery draw. The Slave unit continuously monitors the output of the Master unit. If the Master unit has more than 60% of the rated load (for example, 2100 watts on Freedom SW 3524-230), the Slave unit will assist the Master and

Charger Settings in a Dual Freedom SW Configuration

Stacking Features

The Freedom SW 3524-230 includes a maximum 90A charger. When using two stacked Freedom SW 3524-230 inverter/chargers connected to the same battery bank, a total of 180A (90A × 2) of bulk charging is possible into that single common battery bank. For small battery banks and/or certain battery types this bulk mode current may be too high, therefore Freedom SW 230V models include a battery bank capacity (Batt Capacity) setting and a maximum charge rate (%) (Max Chg Rate) setting.

The battery bank capacity (C) is the bank’s total Amp-hour capacity , which is best determined by a qualified RV electrical technician.

The Max Chg Rate depends on the battery manufacturer's maximum charge rate for the specific battery model being used to construct the bank. This total bank maximum charge rate is best determined by a qualified RV electrical technician. Suitable battery types include Flooded, GEL and AGM. Do not mix different battery types within the same battery bank.

For a Flooded type battery bank, the preferred char ge rate (in Amps) is usually 10-15% of C where C = battery bank’s total Amp-hour capacity . However, the industry-accepted maximum charge rate is 25% of C. Some AGM or Gel battery models may have a maximum charge rate as high as 50% of C and in rare cases, up to 100% of C.

Do not exceed the battery manufacturer’s recommended maximum charge specifications because the resulting battery temperature rise shortens battery life.

Calculations

Once installed and configured, each Freedom SW 230V charger in the dual configuration should be set to its own bulk charge current limit as follows:

Industry accepted maximum charge rate (%)

× battery bank’s total Amp-hour capacity (C)

/2 (for one of the chargers)

× = Maximum charger #1 output current (in Amps)

allowed in bulk mode (also limited to the charger’s maximum capacity)

To calculate the system total bulk output for the stacked pair,

Charger #1

The System Total BULK output current flows into the battery bank. As such, this total bulk current is split/distributed within the bank through each individual parallel and/or series connected battery. Therefore, the current each battery “sees” must not exceed each individual battery’s maximum allowed charge current as specified by the battery manufacturer. Since most battery banks are comprised of the same battery type, model and length of interconnecting cables, current sharing is roughly equal through

each parallel branch of batteries. Therefore, the above generalizations of maximum charge rate (%) can be made for the entire battery bank.

The Freedom SW 230V’s Max Chg Rate (%) setting defaults to 100 (adjustable from 0 to 100). So if the Freedom SW 3524-230 charger with a maximum possible 90A charger capacity is set to a Max Chg Rate of 100 (%) then its full 90A of current can be delivered into the battery bank. However, if this is too high, the installer/operator may reduce the Max Chg Rate setting to suit the system battery type and bank requirements (and limitations), to avoid overheating the battery bank.

The user/installer is responsible of configuring the charger to ensure that the battery manufacturer’s recommended maximum charge rate current (in Amps) is not exceeded to prolong battery life and to exhibit best performance.

Battery Information

Battery Bank Sizing

Battery capacity Battery size or capacity is just as important as the battery type selected for use with the Freedom SW 230V. The batteries are the most important part of your system, so It is recommended that you purchase as much battery capacity as possible. A large battery will extend running time and ensure that your inverter/charger delivers full rated surge.

It is recommended a minimum battery size of 200 amp-hours (Ah) for moderate loads (< 1000 watts) and greater than 400 Ah for heavy loads.

See “Estimating Battery Requirements” for information on a more detailed calculation.

About Amp-hours A number of different standards are used to rate battery energy storage capacity . Automotive and marine starting batteries are normally rated in cranking amps. This is not a relevant rating for continuous loads like an inverter. Deep-cycle batteries use a more suitable rating system such as amp-hours (Ah).

Amp-hour capacity is the number of amps a battery can continuously deliver during a specified number of hours. It is represented by the product of the two —amps multiplied by hours.

52 Freedom SW 230V Installation Guide

A typical single marine or RV battery rated for 100 Ah can deliver 5 amps @12 volts for 20 hours (5 amps × 20 hours = 100 Ah @12 volts). This same battery can deliver a higher or lower current for less or more time, limited approximately by the 100 Ah figure (50 amps for 2 hours or 200 amps for a half hour), but usually the capacity figure given is only accurate for the specified duration (20 hours).

For Freedom SW 230V inverter systems requiring a 24-volt battery bank,

• a pair of 200 Ah@12 volts batteries may be connected in series to create a 24-volt bank of 200 Ah@24 volts capacity,

• while two of these series pair branches may be connected in parallel to create a higher capacity 400 Ah@24 volts battery bank.

Estimating Battery Requirements

Calculating Battery Size

Battery Information

Step 1: Compute Amp-hours

For each appliance, compute the number of amp-hours that will be used between charging cycles, as follows:

1. Obtain the wattage. If the wattage is marked on the nameplate rating, use that. Otherwise, multiply the marked voltage and amperage: WATTS = VOLTS × AMPS.

2. Obtain the Watt-hours by multiplying that amount by the hours the appliance will be used: WATT-HOURS = WATTS × HOURS.

3. Obtain the amp-h ours that the appliance requires by dividing that amount by 20 (the factor for the Freedom SW 230V, which is a 24-volt system): BA TTERY AMP-HOURS USED = AC WATT-HOURS÷10

For example, a 100 W light bulb that is used for 4 hours will use 400 watt-hours (Wh) and the inverter will consume approximately 40 Ah from a 12-volt battery.

4. Enter this information on the blank calcu lation worksheet (page 56).

975-0697-01-01 53

Step 2: Calculate Battery Size

5. Complete the rest of the worksheet; see Table 5, “Battery Sizing Example” on page 54 for an example.

Size the batteries at approximately twice the estimated total amphour usage. Doubling the expected amp-hour usage ensures that the batteries will not be overly discharged and extends battery life.

Do not skip this doubling step. More capacity is better since you will have more reserve capacity, be better able to handle large loads and surge loads, and your battery won’t be discharged as deeply. Battery life is directly dependent on how deeply the battery is discharged. The deeper the discharge, the shorter the battery life.

Troubleshooting If you find that the system shuts down when appliances with large motors are started, the problem may be that this motor is too much for the battery. Even though you calculated the amp-hour requirements appropriately, the startup of a large motor makes high demands on the battery. You may find that adding more amp-hours (in the form of extra batteries or replacement with a bigger battery) solves the problem.

Battery Banks

As your power requirements increase, you may need to use more than one battery to obtain sufficient capacity. Batteries can be connected in parallel, in series, or in series-parallel to create higher capacity systems.

See “Battery Cabling and Hook-up Configurations” on page 57 for more information about battery inter-connection schemes.

Mixing Batteries Batteries connected in parallel should be of the same type and amp-hour rating and from the same manufacturer.

It is not recommended to connect batteries of different types, amphour ratings or manufacturers. Improper charging and decreased battery life will result.

Battery Bank Sizing Worksheet

The following worksheet is a guide to help you determine your battery needs. Be generous in estimating the time for which you will run each of the loads to ensure sufficient battery capacity.

Battery Information

Restrictions on Motor Size

An appliance may require three to six times its normal running current in order to start. The Freedom SW 3524-230 can handle surges to 6800 watts for five seconds, which translates to a lockedrotor-amp rating of no more than 50 amps. The locked rotor amp may be specified on the motor nameplate as “LRA” or “LRI”.

When considering appliances with large motors, follow these guidelines:

• Make sure that the motor’s LRA rating is no more than 50 amps. The Freedom SW 230V may not be able to start a motor with a higher LRA, and the Freedom SW 230V will shut down if the attempt is made.

• Make sure the battery bank, DC cables and DC fuses are capable of handling up to 600 amps DC for five seconds. A weaker circuit may not be able to provide sufficient power to the Freedom SW 230V to allow the Freedom SW 230V to start up the appliance. Again, if the circuit cannot deliver the required current, the system may shut down or the fuse may open.

Battery Cabling and Hook-up Configurations

12VDC 100 Ah

24 V 100 Ah

Several smaller batteries can be connected to create a battery bank of substantial size. You can connect batteries in series (see “Battery Series Connection” on the right) or series-parallel (see “Battery Series-Parallel Connections” on the next page).

To make a larger battery bank, connect individual batteries with heavy cables. The actual size of the cable depends on whether the batteries are connected in parallel or series. Generally, the cable should not be smaller than the inverter cables—if the main cables are 120 mm

, the battery interconnects should be 120 mm2.

The best configuration is to connect the batteries in series-parallel. This requires additional cables, but reduces imbalances in the battery bank and can improve the overall performance. Consult your battery supplier for more information regarding the hook-up configuration required for your system.

Battery Series Connection

When batteries are connected with the positive terminal of one battery to the negative terminal of the next battery, they are connected in series. In a series configuration, the battery bank has the same Ah rating of a single battery, but an overall voltage equal to the sum of the individual batteries. See below.

Battery Series-Parallel Connections

As the name series-parallel implies, both the series and parallel configurations are used in combination. The result is an increase in both the voltage and the capacity of the total battery bank. This is common with all battery-inverter system voltages. The smaller, lower voltage batteries are first connected in series to obtain the necessary voltage, and then these “batteries connected in series” sets are connected in parallel to increase the battery bank capacity.
