GENERAL OPERATIONS INSTRUCTIONS
When the Inverter/Charger is first connected to the battery bank, the ON/OFF switch must be lightly pressed to turn the Inverter ON. Once the Inverter has been turned ON, pressing the ON/OFF switch turns the Inverter on and off.
WARNING: The ON/OFF switch does not turn the battery charger on or remove AC pass-through mode. If AC power is connected to the AC Input, this AC power will also be available on the AC output and is not controlled by the Power ON/OFF switch. If the button is pressed it will start to flash. Once shore power is removed, the inverter will turn off. If the ON/OFF button is not pressed and shore power is removed the inverter will stay on and start to pick up the load.
The IC Series has two basic operating modes: Inverting and AC power pass-through. Within these two modes the Inverter/Charger functions differently depending on the load power and shore power specifications/requirements. These different operating modes are outlined over the following pages.
When the Inverter in the IC Series is turned ON, the automatic search function is enabled. This feature is used to conserve battery power when no AC power is required (no appliances being used).
In search mode the Inverter/Charger continually scans the AC output looking for an AC load (appliance turned on). When an AC appliance is turned on, an AC load is registered at the AC output and the Inverter switches ON and supplies AC power (from the battery bank) to the appliance.
The AC load required to switch the Inverter ON is set to 5W as a factory default value. The search feature can be turned OFF and can be adjusted between 5 and 50W—to adjust these values the GP-IC-Remote must be used (this can be purchased separately from Go Power!).
BATTERY CHARGER SPECIFICATIONS
The IC Series Inverter/Charger is equipped with a PFC (Power Factor Corrected) and PI (Proportional Integral) multistage battery charger. These 2 features maximize the real power from AC Shore Power. The multistage battery charger can use up to four different charging stages to help monitor and keep the batteries healthy.
Bulk Charging: This is the initial stage of charging. While bulk charging, the charger supplies the battery bank with controlled constant current. The charger will remain in bulk charge until the absorption charge voltage is achieved.
Absorb Charging: This is the second charging state and begins after the absorb voltage has been reached. Absorb charging provides the batteries with a constant voltage and reduces the DC charging current in order to maintain the absorb voltage setting. The factory default setting for absorb charging is 2 hours. After 2 hours of absorb charging, the charger switches to final charge.
Final (Float) Charging: The third charging stage occurs at the end of absorb charging time. While final charging, the charge voltage is reduced to the final charge voltage set point. In this stage, the batteries are kept fully charged and ready if needed by the Inverter. The final (float) charging stage reduces battery gassing, minimizes watering requirements, and ensures the batteries are maintained at optimum capacity.
Equalization Charging: The EQ charging is used to stir up stratified electrolyte and to reverse any battery plate sulfation that may have occurred. The EQ charging mode can only be used with the GP-IC-Remote, sold separately by Go Power!.
