INSTALLATION OPTIONS

Installation Option #1

The inverter is used in a Single Input/Single Output mode. Up to 30 amps is transferred through the FP3000-12 with the charger sharing power with all of the AC loads.

In this installation example, a single 30-amp shorepower source is available and all AC loads are supplied power through the inverter in charge/transfer mode, or by the inverter in invert mode. The charger shares power with the AC loads and can transfer up to 30 amps. The AC input power must be supplied through a 30-amp branch rated main breaker.

In this type of system, the panel loads would normally not include any heavy loads such as space heaters, stove, water heaters, air conditioners, AC to DC converters, or other battery chargers. If these types of loads are present, they should be turned OFF when the inverter power is being used to prevent overloading the inverter or rapidly discharging the battery bank. To avoid the need for this manual form of energy management, installation option #2 should be considered.

If a generator is installed in the system, a break-before-make AC transfer switch is used to select between shore or generator power. The transfer switch AC output is then routed to the input of the inverter/charger.
