The EG4 18kPV (model EG4-18kPV-12LV) is EG4's proven 48V split-phase hybrid inverter. It combines solar charge control, battery charging and inverter output in one outdoor-rated box. It delivers 12kW of continuous 120/240V power, accepts up to 21kW of recommended solar across three MPPTs, and charges batteries at up to 250A. It can run grid-tied, grid-assisted or fully off-grid, and up to 10 units can be paralleled for larger homes and light commercial sites.
Highlights
- All-in-one: MPPT charge controllers, battery charger and inverter in a single unit, with no separate charge controller or transformer
- Whole-home output: 12kW continuous at 120/240V split phase for essential and larger household loads
- High solar capacity: 21kW recommended PV, 600VDC max, 3 MPPTs
- Flexible operation: grid-tied, grid-assist or off-grid; also works as battery backup without solar
- Expandable: parallel up to 10 units
