Overview
Whole-home off-grid power, stored indoors.
This bundle pairs the EG4 12000XP, a 12,000W off-grid inverter with an 18,000W surge and up to 24kW of solar input, with one or two EG4 314Ah Indoor WallMount batteries (16kWh each).
It runs 120/240V split phase, so it can carry central AC, a well pump and the rest of the house. It can also use the grid or a generator to charge and pass through power.
Each battery is rated for 10,000 cycles at 80% depth of discharge, heats itself in the cold, and runs silently with no fans. Up to 16 batteries can run in parallel as your needs grow.
This is an off-grid system and does not sell power back to the grid. EG4 covers the inverter for 5 years and each battery for 10 years or 10,000 cycles.
Choose your kit
Build it around how you'll use it.
Every kit starts with the same power station. What changes is the panels, and whether it connects to your home.
- Pick your starting point Choose the power station on its own if you already have panels, or a kit if you are starting from scratch.
- Match the panels to your life Folding panels pack away for the RV and campsite. Rigid panels suit a cabin, shed or backyard. The transfer switch connects to your home.
- Let us help you set it up Every order comes with our setup guide and lifetime support from the team, before and long after delivery.
