EG4® 12kPV HYBRID INVERTER
The EG4 12kPV is a 48V split-phase, hybrid inverter/charger capable of utilizing 12kW of PV input and efficiently outputting 8kW of power while also charging your battery bank. Parallel up to 10 units for 80kW of output power and control multiple stations and units using the new EG4 monitoring software.
Key Features
- HIGH FREQUENCY SPLIT-PHASE DESIGN
- 10-YEAR WARRANTY
- REMOTE ADJUSTMENT VIA EG4 SOFTWARE
ALL-IN-ONE HYBRID INVERTER
Capable of running entirely off the grid, using grid electricity, or selling power back to the grid.
UP TO 600VDC INPUT
The extra high voltage enables lower cable sizing for the 2 MPPTs and a maximum recommended PV input of 15kW, eliminating the need for a combiner box.
PLUG IN WI-FI DEVICE
Enables wireless connection between our new monitoring platform and the 12kPV through the EG4 app or EG4 Monitor system.
CLOSED-LOOP COMMUNICATIONS
Able to communicate with EG4 48V batteries and other battery brands. A battery firmware update is required for closed-loop communications with LifePower4 batteries.
RAPID SHUT DOWN
The 12kPV is CSA C22.2#330:2017 and NEC 690.12 ready with its built-in RSD capabilities.
