3 PRODUCT DESCRIPTION

The CombiMaster Inverter/Charger is a battery charger, inverter and AC transfer system in one compact case.

3.1 Overview of the connections

Front side with open connection compartment

Bottom side

Figure 2. Connections

1 Grounding system jumper 2 AC input 3 Status LEDs 4 Positive battery terminal [M8 screw] 5 Negative battery terminal [M8 screw] 6 AC output power 7 DIP switches

3.2 Operating modes

• Inverter mode; When there is no external AC power available, the inverter provides AC power on the AC output. If energy saving mode is enabled, battery power consumption will be reduced when there is no (i.e. less than 20W for 10 seconds) load on AC OUT. Please note that small loads such as wifi routers, satellite receivers or digital clocks are most likely not to work in this mode.

AC IN AC OUT

BATTERIES

Page 8

CombiMaster 120V Series – User and Installation Manual

• Charger mode; When external AC power is available on the AC input, the battery will be charged and the AC output is supplied by the external power.

• Power sharing mode; The CombiMaster Inverter/Charger automatically reduces its battery charger output when the load connected to AC OUT increases while the available power at AC IN is limited. This avoids the external AC circuit breaker from tripping. The power sharing level, i.e. AC IN Limit setting (adjustable from a display), should be set to match the value of the external circuit breaker.

Load on AC OUT < AC IN Limit

Load on AC OUT ≥ AC IN Limit

• AC input support mode; If the demand for AC power still increases, the external AC circuit breaker may still trip if nothing is done. This problem can be solved by the AC IN support mode. If the total demand for energy exceeds the maximum external power supply, energy can be added to AC OUT by means of the inverter. This means that the inverter adds energy from the batteries, in parallel with the external power source.

CAUTION!

The continuous load connected to AC OUT should never exceed 40A. Exceeding the max. allowable output current may damage the CombiMaster Inverter/Charger.

Note: Different countries have different regulations regarding AC sources operating in parallel with

the AC grid. This may mean that in some situations AC IN support mode is not allowed! Familiarize yourself with local regulations on this issue. AC power from the inverter will never be fed back into the AC grid.

See chapter 5 on page 19 for the required settings.

3.3 Remote control

The CombiMaster Inverter/Charger can be monitored from a remote panel like the SmartRemote or a Touch 5 (in a CZone network). Some settings can only be adjusted from a laptop/notebook or PC connected to the CombiMaster Inverter/Charger via a USB Interface.

3.4 Protection

• Overload or short circuit; while in the inverter mode, the CombiMaster Inverter/Charger will shut down after 5 seconds of 200% overload or after 10 seconds 150%.

• Transfer switch overload; the transfer switch of the CombiMaster Inverter/Charger is protected against overload and short circuit. When the current through the transfer switch of the CombiMaster Inverter/Charger is too high, the thermal fuse (item 8 on page 7) will disconnect the AC input.

• High temperature; if the ambient temperature of the CombiMaster Inverter/Charger exceeds 104°F [40°C], it will reduce power. If it exceeds 140°F [60°C], it will shut down, trigger the status LEDs and optionally a remote alarm. As soon as the temperature drops below the factory default threshold, the inverter is powered up automatically or the charger resumes its charge current.

• Battery low/high; the CombiMaster Inverter/Charger can warn for low or high battery voltages by triggering status LEDs and CZone/MasterBus alarms.

CAUTION!

The CombiMaster Inverter/Charger is not protected against:

- serious over voltage on the AC input;

- serious continuous overload on the AC output. Make sure AC input is within the range of 90-135V

and the continuous load connected to

AC OUT never exceeds 40A.

See section 6.2 on page 26 for an overview of the status LEDs. See chapter 5 on page 19 for the required settings.

4.9 System integration (CZone/MasterBus)

The CombiMaster Inverter/Charger can be connected to a CZone or MasterBus network.

• CZone network Points to consider:

˗ Up to 40 devices can be connected together on a single backbone. ˗ Make sure the CZone network has two terminating resistors, one at each open end of the

backbone.

˗ The electric power for the network comes from a battery or power supply. Make sure that it

delivers enough power and is positioned as close to the middle of the backbone run as possible to reduce voltage drop.

˗ Each device on the CZone network has a unique CZone address; the Dipswitch. This number is

usually assigned automatically during configuration and must match the DIP switch settings. This is done in the CZone Configuration Tool.

• MasterBus network Use an RJ45 MasterBus cable (not included) and daisy chain the CombiMaster Inverter/Charger to

the other MasterBus devices, forming a local data network. Points to consider: ˗ Connections between the devices are made by standard MasterBus cables. Mastervolt can

supply these cables.

˗ Up to 63 MasterBus devices can be connected together. ˗ MasterBus needs a terminating device on both ends of the network. ˗ The electric power for the network comes from the connected devices according to the rule:

1powering / 3 non-powering. Spread the powering devices over the network

˗ Do not make ring networks. ˗ Do not make T-connections in the network.

CAUTION!

Never connect a non-MasterBus device to the MasterBus network directly! This will void warranty of all MasterBus devices connected.

For more details on networks, please contact your Mastervolt supplier.

5 SETTINGS

Adjustment of the settings of the CombiMaster Inverter/Charger can be made in two different ways:

• By means of DIP switches.

• From a laptop connected to the CombiMaster Inverter/Charger via a USB Interface. Some settings,

like the AC IN Limit setting for example, can only be changed in this way.

CAUTION!

Invalid settings of the CombiMaster Inverter/Charger can cause serious damage to your batteries and/or the connected load! Adjustment of settings must be carried out by authorized personnel only.

5.1 DIP switch settings

Use a small screwdriver to carefully set the required settings.

DIP switch 1 = CZone network (0) or MasterBus network (1). DIP switch 2 = MasterBus powering off (0) or on (1) DIP switches 3 to 10 are either used as CZone address or for

MasterBus battery and 3rd output settings.

Figure 4. DIP switches (factory settings)

In a CZone network: DIP switch 1 must always be set to the OFF position (0 ). DIP switch 2 must always be set to the OFF position (0 ). DIP switches 3 to 10 must match the unique address used in the CZone network; the dipswitch (see the CZone Configuration Tool Instructions manual).

In a MasterBus network:

DIP switch 1 must always be set to the ON position (1 ). DIP switch 2 is MasterBus Powering ON (1 ) or OFF (0 ). By default, this is OFF. DIP switches 3 to 5 are used for battery type selection:

6 OPERATION

6.1 Switching On / Charge only

The main switch on the bottom of the CombiMaster Inverter/Charger has two positions:

• Inverter and charger on (I)

• Charge only, inverter off ().

Note: When the main switch is in this position (), it consumes 1mA DC power when not connected to AC. Switching off the inverter remotely, increases the DC power consumption. If it is necessary to put the CombiMaster Inverter/Charger out of operation, for winter storage for example, it is strongly recommended to switch the inverter off by the main switch

CombiMaster 120V Series – User and Installation Manual

6.3 3-step+ charge process

Battery charging is accomplished in three automatic stages: BULK, ABSORPTION and FLOAT. The first step is the BULK phase, in which the output current of the charger is 100%, and the greater part of the capacity of the battery is rapidly charged. The current charges the batteries and gradually the voltage rises to the BULK voltage. The duration of this phase depends on the ratio of battery to charger capacity, and the battery state of charge.

Figure 6: 3-step charge algorithm. See section 8.2 for detailed information.

The BULK phase is followed by the ABSORPTION phase. Absorption charging starts when the voltage on the batteries has reached the BULK voltage and ends when the battery is completely full. Battery voltage remains constant throughout this stage, and the charge current depends on the degree to which the battery was initially discharged, the battery type, the ambient temperature, etc. This stage lasts for 4 hours maximum. Once the battery is 100% full, the CombiMaster Inverter/Charger automatically switches over to the FLOAT phase.

Connected DC loads are powered directly by the charger. If the load exceeds the charger capacity, the required additional power comes from the battery, which will be progressively discharged until the charger automatically switches back to the bulk phase. Once consumption decreases, the charger goes back to normal operation of the 3-step+ charge system.

Connected to the CombiMaster Inverter/Charger, the batteries can be left unattended for weeks or months. One hour every 14 days the charger automatically switches to ABSORPTION to keep the battery running properly and prolong its life span. The 3-step+ charge system is also safe for all the connected equipment.

WARNING!

The MLI charging voltages on this charger fit the Mastervolt Li-ion (MLI) batteries but do not necessarily fit other Li-ion batteries! Always follow the instructions provided by the battery manufacturer!

Page 28

CombiMaster 120V Series – User and Installation Manual

6.4 Temperature compensated charging

By installing the battery temperature sensor sensor (for Lead Acid batteries only), the charge voltages are automatically adapted for deviating temperatures.

When the battery temperature is low, the charge voltage increases. On the other hand, when the battery temperature is high, the charge voltage is decreased. Overcharge and gassing are prevented this way. This will extend the life of your batteries.

Figure 7: Temperature compensated charging

6.5 Reset the thermal fuse after an overload

A thermal fuse protects the transfer switch of the CombiMaster Inverter/Charger against overload. If the status LEDs indicate an overload, proceed as follows:

Step 1. Turn off AC power. Step 2. Move the main switch of the CombiMaster Inverter/Charger to the "Charge only" position (). Step 3. Disconnect the CombiMaster Inverter/Charger from any power source. Step 4. Disconnect all loads from the CombiMaster Inverter/Charger. Step 5. Investigate the cause of failure of the thermal fuse like overload or short-circuits. Step 6. Wait for at least two minutes and then reset the fuse by pushing the button at the bottom side of

the CombiMaster Inverter/Charger.

Step 7. Connect the CombiMaster Inverter/Charger to the power sources again. Step 8. Move the main switch of the CombiMaster Inverter/Charger to the On position (

Page 29

CombiMaster 120V Series – User and Installation Manual

6.6 Maintenance

No specific maintenance to the CombiMaster Inverter/Charger is required. Examine your electrical installation on a regular basis, at least once a year. Defects such as loose connections, damaged wiring etc. must be corrected immediately.

If necessary, use a soft clean cloth to clean the CombiMaster Inverter/Charger. Do not use any liquids or corrosive substances, such as solvents, alcohol, petrol or abrasive components.

6.6.1 Decommissioning

If it is necessary to put the CombiMaster Inverter/Charger out of operation, follow the instructions in order of succession as described below:

Step 1. Turn AC power off. Step 2. Remove the DC fuse(s) and disconnect the batteries. Step 3. Remove the AC fuse(s) of the AC input and/or disconnect the AC IN. Step 4. Open the connection compartment of the CombiMaster Inverter/Charger by loosening the two

screws at the bottom and then lifting the front cover plate. The connectors for the battery, the AC and the remote panel are now visible.

WARNING!

Never remove the front panel while the CombiMaster Inverter/Charger is still connected to a power source!

Step 5. Check with a suitable voltage meter whether the inputs and the outputs of the CombiMaster

Inverter/Charger are voltage free.

Step 6. Disconnect all the wiring.

Now the CombiMaster Inverter/Charger can be demounted in a safe way.

6.6.2 Storage and transportation

When not installed, store the CombiMaster Inverter/Charger in the original packing, in a dry and dust free environment.
