EG4 3000 EHV-48V All-In-One Off-Grid Inverter

Take your first real step toward energy independence — powering your cabin, RV or workshop on your own terms — with the EG4 3000 EHV-48V All-In-One Off-Grid Inverter.

Why You'll Love The EG4 3000 EHV-48V

1. A simple, affordable way into off-grid power. The inverter, MPPT solar charger and battery charger are built into one compact 21.6 lb unit, so you get a complete off-grid setup without juggling separate components.
2. Clean, reliable power for your space. It delivers 3,000W of continuous pure sine wave power at 120V — enough to keep the essentials running in an RV, cabin or small workshop.
3. Room to grow when you're ready. It takes in up to 5kW of solar today and parallels with up to 12 units for as much as 36kW down the line, so your system scales right along with your ambitions.
4. Everything you need in the box. A bonus kit with a Wi-Fi adapter, UL-listed breaker and battery cables is included, so you can mount it with a few screws and get running fast.

Your life, with the EG4 3000 EHV-48V

Maybe you've been dreaming about it for a while. A cabin off the beaten track. Weekends in the RV without hunting for hookups. A workshop out back that runs on your own power, not the utility's.

The EG4 3000 EHV-48V is a straightforward way to get there. Mount it with a few screws, connect your panels and batteries, and you've got clean 3kW power ready when you need it. Through the day your solar charges the batteries, and the inverter quietly turns that stored energy into everyday household power.

It's built to be lived with. The closed-loop connection to your EG4 48V batteries keeps everything in sync, so you can check your charge level and power flow right on the LCD screen or from your phone. And when your needs grow, you simply add another unit.

There's some smart thinking under the hood, too.

Three selectable operating modes — SBU, SUB and UTL — let you decide how the EG4 3000 EHV-48V prioritizes solar, battery and grid or generator power. So you can lean on the sun as much as possible, or hold your batteries in reserve for emergencies. Larger battery terminals accept up to 2 AWG cable for a solid, confident connection, and built-in overload, over-temperature and short-circuit protection quietly watches your back.
