EG4 18kPV Hybrid Inverter
An all-in-one box that runs solar, a battery bank, and the grid. 12kW continuous output, up to 18kW of PV input across three MPPT trackers, and a built-in 200A wirebox so you wire fewer parts on the wall. NEMA 4X rated, so it goes indoors or out, and it parallels up to 10 units as the loads grow.

One box for whole-home backup.
The EG4 18kPV is a 48V split-phase hybrid inverter that handles solar, battery storage, and the grid through a single unit. It puts out 12,000W continuous at 120/240V, takes a big array on three MPPT trackers, and runs on or off the grid depending on what the house needs. It is built for homeowners who want backup power, lower bills, and a system that can grow.
12kW hybrid output
12,000W continuous at 120/240V split-phase, enough to carry essential loads and larger whole-home systems.
Triple MPPT solar input
Three trackers and room for up to 21,000W of recommended PV, so the array keeps producing as shade and sun move across the roof.
Built-in 200A wirebox
Breakers and the wirebox are integrated, so there are fewer separate parts to mount and wire on the wall.
On-grid or off-grid
Runs grid-tied, grid-assist, or fully off-grid. Set it up for the house you have, and change it as needs change.
NEMA 4X / IP65 rated
The enclosure is rated for indoor or outdoor installs, so it holds up in a garage, a utility room, or out on the wall.
Parallel to 10 units
Start with one and stack up to ten. The system scales with the house, not the other way around.
The 18kPV is a strong pick for whole-home backup, off-grid homes, cabins, workshops, and homesteads that want a single inverter doing the work. Remote monitoring and firmware updates run through the EG4 app, so you can check production and tune settings from anywhere. If you want more output per unit, look at the FlexBOSS21.
