FGH Seriesis a single-phase off-grid solar inverter combining inverter, MPPT solar charging and AC battery charging in one compact unit.
Available in 3 kW, 3.6 kW, 5 kW and 6 kWmodels for residential, commercial and remote power applications.
Flexible energy management:Solar, utility and battery priority modes adapt the system to different power conditions.
Reliable power output:Pure sine wave output supports household appliances, office equipment and compatible motor loads.
Battery and monitoring flexibility:Supports 48 V lead-acid and lithium batteries, with CAN, RS485, USB, dry contact and optional wireless monitoring.
Scalable operation:Up to 6 unitscan operate in parallel for higher system capacity.
PV array, battery capacity and charging configuration are selected according to the project load.
