Felicity IVGM20KLP3G1 20kW three-phase hybrid inverter (48V low voltage, IP65)
The Felicity IVGM20KLP3G1 is a three-phase hybrid solar inverter for low-voltage battery storage (40–60V) and high-output PV input. This inverter combines inverter functionality with solar charge control and battery charge/discharge control, and is designed for systems with self-consumption, grid feed-in, and backup via EPS. Thanks to dual MPPT and multiple PV strings, the system is flexible in design, with support for three-phase load imbalance.

Installation advice
For safe and trouble-free operation, correct sizing of PV strings (voltage/current), DC protection, grounding, and grid settings is essential. Preferably use BMS communication (RS485/CAN) with a compatible 48V battery and configure the inverter according to the local grid code and installation standards. Installation must be carried out by qualified personnel.
