Overview
One outdoor system for the whole home.
This bundle pairs the EG4 18kPV, a 12,000W hybrid inverter with 18,000W of solar input across three MPPTs, with the EG4 WallMount AllWeather battery. Choose one battery for 14.3kWh or two for 28.6kWh.
Both parts are built to live outside. The battery is IP65 rated with self-heating for cold weather, the inverter is NEMA 4X, and the conduit box joins them into one clean wall-mounted system.
The 18kPV runs on 120/240V split phase, so it can carry central AC, a well pump and the rest of the house. Use it grid-tied with backup, or fully off-grid with a generator as your fallback.
Each AllWeather battery is rated for more than 8,000 cycles at 80% depth of discharge, and EG4 covers both the inverter and batteries for 10 years. Paired together they are listed to UL 9540 as an energy storage system.
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.
