Growtech Axpert GT 3.6kW Inverter 24V

3.6kW inverter with solar charging and lithium activation

The Growtech Axpert GT 3.6kW inverter combines pure sine wave AC output with a built-in 100A MPPT solar charge controller for residential and small commercial power systems. Its 24V battery system supports solar and AC charging, with a maximum PV array power of 4000W.

Lithium battery activation can help recover a battery that has entered protection mode after over-discharge. An LCD display puts system information and settings on the inverter, while optional Wi-Fi monitoring is available through a separate dongle. With no parallel capability, this model is intended for single-inverter installations.
