EG4 3000 EHV-48V

EG4 3 kW Off-Grid Inverter (48 V → 120 V)

The EG4 3 kW Off-Grid Inverter (3000EHV-48) is a robust all-in-one off-grid power solution combining a pure sine-wave inverter, MPPT solar charger, and battery charger into a single compact unit. Designed for off-grid residential, cabin, RV, and critical load applications, this inverter delivers reliable 120 VAC power from a 48 V battery bank while also managing solar input and battery charging.

Key Features

Reliable Off-Grid Power

• 3,000 W continuous AC output at 120 VAC (pure sine wave).

• Supports essential household loads such as lighting, refrigerators/freezers, and mini-split air conditioners.

• Surge capacity typically handles transient peaks up to ~6 kW for short durations.

Integrated Solar & Battery Management
