EG4 Electronics, all-in-one off-grid inverter
EG4 6000XP Off-Grid Inverter
Also written as EG4 6000XP, EG4 6kXP, 6000XP
A 6 kW, 120/240 V split-phase inverter with two built-in MPPT charge controllers, a battery charger and a generator port, for 48 V battery banks.
Best for
A cabin, barn or farm building that needs 240 V for a well pump or shop tools, with room to add units later.

Strengths and limitations
Strengths
- 6 kW continuous at 120/240 V split-phase (EG4 dealer).
- Two MPPT inputs, 8,000 W of panels used (4,000 W each), 480 V max, best between 120 and 385 V (EG4).
- Dedicated generator port and 50 A AC bypass; up to 16 units in parallel (EG4).
- UL 1741; 5-year standard warranty (EG4).
Limitations
- Draws about 50 W idling on battery, around 1.2 kWh a day before any load (EG4 figure; the daily total is our arithmetic).
- EG4 recommends at least 200 Ah of 48 V battery per inverter.
- 52.9 lb; 18 x 25.5 x 5.25 in; fan cooled (EG4).
What it does not do
- Export to the grid: it is an off-grid inverter, not a hybrid.
- Ride out long cloudy stretches on a purely off-grid site without a backup generator; EG4 recommends an 8 to 12 kW two-wire-start generator.
- Go outdoors: it is rated IP20.

- EG4 6000XP user manual, EG4 Electronics (manual copy) (manufacturer), read 2026-11-10. Can run in off-grid only mode. Purely off-grid systems should strongly consider a 2-wire start backup generator for extended cloudy periods (8 to 12 kW diesel recommended, 8 kW minimum per inverter). Two MPPT inputs, 480 V max, optimal 120 to 385 VDC.
