The Go Power! Inverter Charger is a breakthrough product where you get top features, quality, and performance at an economical price. The inverter charger is a 3-in-1 system combining an inverter, battery charger and automatic transfer switch. This saves space and simplifies installation by reducing the number of devices and cables to install. While most inverter chargers offer a 30 Ampere transfer switch, the IC2000 provides two 50 Ampere legs. That means when connected to shore power 50 Ampere service (240 Volt), you can draw up to 12,000 Watts of power. The temperature data is sent to the IC2000 which automatically adjusts Voltage to maintain proper and healthy charging.
