One-stop PV power plant

XPI series SolarCharger&Inverter

Integrated with controller, inverter, AC bypass switch, transformers, solar and DC battery terminal, protection breakers and LCD display

Auto-switch smoothly transfer the load to utility power or battery

Auxiliary-Charging could complement power to battery by utility power even if PV array does not work in raining days.

Low frequency transformer design allows to withstand high inrush load current supports fan, pump, refrigerator, TV, lamp etc

MPPT technology can save 20~30% solar panels Integrated RS232 serial communications Prior solar charging function use the renewable

energy while utility power is complementary
