1.0 Important Safety Instructions

Warning: Before you install and use your Go Power! Smart Converter/ Charger,

be sure to read these safety instructions.

1.1 General Safety Precautions

1. Do not expose the GP Smart Charger to rain, snow, spray, bilge, or dust. To

reduce risk of hazard do not cover or obstruct the ventilation openings.

2. Do not install the GP Smart Charger in a zero-clearance compartment.

Overheating may result.

3. To avoid a risk of fire and electronic shock, ensure that existing wiring is in

good electrical condition; and that wire size is not undersized. Do not operate the GP Smart Charger with damaged or substandard wiring.

4. The battery terminal not connected to the chassis has to be connected first.

The other connection is to be made to the chassis, remote from the battery and fuel line. The battery Smart Charger is then to be connected to the supply mains.

5. After charging, disconnect the GP Smart Charger from supply mains. Then

remove the chassis connection and battery connection, in this order.

6. Do not charge non-rechargeable batteries.

7. During charging the battery must be placed in a well-ventilated area.

8. The battery Smart Charger must only be plugged-in to a grounded outlet.

9. If the power supply cord is damaged, the manufacturer or its service agent

or a similar qualified person must replace it in order to avoid a hazard.

2.0 Features

The Go Power! Smart Converter Charger (GPC) series power converter / battery charger converts 120 V nominal AC to 13.6 V DC. As a power supply, its tightly controlled regulation allows the user to operate any 12 V nominal DC load up to

the converter’s rated output current. As a battery charger, the converter will

maintain the battery, delivering its full-rated current when the battery capacity falls sufficiently low. The voltage is set to deliver its maximum current for the necessary period of time that minimizes undue stress to the battery caused by heating of its cells. This helps to ensure the longest possible life of the battery. Over time, as the battery nears its full capacity, the converter will float charge the battery to prevent self-discharge of its cells.

2.1 Protection Features

The GPC MAX is designed with high-quality components to help ensure years of continuous use. Multiple protection features for a long, trouble-free life protects the GPC MAX.

 Reverse Battery Polarity Protection.  Brown-Out Input Protection.  Over-Current Protection: Cycle-by-cycle peak limiting as well as rated

current limiting to maximize the life of the converter.

 Over-Temperature Protection: In addition, it is designed with a unique

proportional fan control circuit. Fan speed is directly proportional to the converter’s internal ambient temperature. This enables the fan to turn on and off very slowly, minimizing unwanted fan-starting noise.

 4 stage battery charging for battery longevity

Disclaimer

* This unit is designed for flooded lead acid and AGM batteries only. Gel

Cells can be damaged by the higher charge voltages of this unit.

2.2 Electrical Specifications

2.3 Installation

Disconnect the positive side of the battery before installation. Connect the positive (red) and negative (black) terminal lugs to battery or load. Always use the proper size wire based on the amperage of the converter and the battery.

When connecting to a battery, a breaker should be installed within 18” of the

battery, connecting the battery positive to the line side of the breaker, and the GPC to the load side. Connect Chassis Bonding Lug on the GPC to vehicle chassis or other grounding source.

2.4 Mounting Location

The GPC can be mounted in any position within an enclosed or interior compartment. Provide sufficient air space to allow unrestricted airflow in and around the unit.

GPC-35-MAX / 45-MAX / 55-MAX / 75-MAX / 100-MAX

___________________________________________________________

2.5 120 Volt AC Input

Plug the GPC AC input cord into a 120 V 3 wire grounded source. See chart for maximum current draw and required input voltages.

2.6 Reverse Polarity Fuses

The GPC is protected against reverse polarity on the DC output. If a battery or the GPC is hooked up incorrectly, the fuses will blow and can be easily replaced. Always use the same size and style fuse that came with the converter. To change the fuses, use a screwdriver to loosen the screws and remove the fuses. Always replace the fuses with the same type and rating. After inserting the new fuses, tighten the screws firmly. DO NOT OVERTIGHTEN.

3.0 Installation Guidelines

There are no components within the GPC that, in their normal operation, produce arcs or sparks. However, all electronic devices have some potential for generating sparks in the event of failure. Therefore, never install this device in the same compartment with flammable items such as gasoline or batteries.

3.1 Installation

Disconnect the positive side of the battery before installation. Connect the positive (red) and negative (black) terminal lugs to battery or load. Always use the proper size wire based on the amperage of the converter and the battery.

When connecting to a battery, a breaker should be installed within 18” of the

battery, connecting the battery positive to the line side of the breaker, and the GPC to the load side. Connect Chassis Bonding Lug on the GPC to vehicle chassis or other grounding source.

3.2 Mounting Location

The GPC can be mounted in any position within an enclosed or interior compartment. Provide sufficient air space to allow unrestricted airflow in and around the unit.

3.3 120 Volt AC Input

Plug the GPC AC input cord into a 120 V 3 wire grounded source. See chart for maximum current draw and required input voltages.

3.4 Reverse Polarity Fuses

Always use the same size and style fuse that came with the converter. To change the fuses, use a screwdriver to loosen the screws and remove the fuses. Always replace the fuses with the same type and rating. After inserting the new fuses, tighten the screws firmly. DO NOT OVERTIGHTEN.

4.0 Charge Controller Options

4.1 GPC Charging

The optional GPC allows the GPC to operate as an automatic three-stage smart charger giving the customer the benefit of a Bulk, Absorption, and Float stage charging. The charging capacity of the GPC is increased, charge times are decreased, proper and safe battery charging is ensured, and overcharging is minimized. The GPC monitors the battery at all times. If the GPC voltage remains in the float stage for more than seven days, the GPC automatically delivers a boost charge as a 4th stage called equalize for a predetermined time, then automatically returns to the normal float stage. The GPC series is recommended for flooded lead acid and AGM batteries only.

Note: Check with your batteries manufacturer specifications to confirm the GPC MAX charger will work.

4.1.1 Reduced Charge Times

The Bulk stage allows the batteries to be charged from the full rated load of the battery. During this stage the batteries are recharged quickly to reduce charge times.

4.1.2 Increased Battery Capacity

After the Bulk stage, the batteries are held in the Absorption stage for a controlled period, ensuring a full and complete charge.

4.1.3 Reduced Battery Stress

During the Float stage, the GPC charge voltage is reduced. This minimizes gassing while maintaining a full charge at the nominal rate of the battery.

4.1.4 Weekly Equalization for Longer Battery Life

If the batteries have not received a smart charge during a seven-day period, the GPC initiates an equalization stage to top off the batteries, dissolving any sulfate on the battery's internal plates and avoiding stratification.

4.1.5 Voltages

The charging voltages used to charge the battery during the three stages differ depending on the voltage of the battery being charged. If you need to know the various voltages, you can calculate them as follows:

1. Determine the number of cells your battery has. Each cell is 2 volts.

2. Multiply the number of cells by the appropriate voltage for the individual

charging stage. Use the following table for reference:

Example: A 12 V battery (6 cells) will Bulk charge at 14.76 V (6 x 2.46).
