Why You'll Love The EG4 18kPV
-
True energy freedom — off-grid, grid-tied or both. The EG4 18kPV runs entirely off the grid, works right alongside it, or sells your excess solar back, so you decide how you power your home and how much you lean on the utility.
-
Serious whole-home power. With 12kW of continuous output and 18kW of solar input, it has the muscle to run a whole house — and parallels up to 10 units for a combined 120kW when you need even more.
-
Backup that's ready when the grid isn't. It doubles as a backup power system, even without solar, keeping your lights on and your fridge running straight through an outage.
-
Built for the outdoors, covered for a decade. It's fully outdoor-rated (NEMA 4X) and backed by a 10-year warranty, so it stands up to the elements and to time.
Your life, with the EG4 18kPV
Think about what your home costs you every month — and how much of that goes straight to the utility. Now picture your roof doing the work instead.
With the EG4 18kPV, your solar powers the house first, charges your batteries, and sends the extra back to the grid. When the sun's down or demand spikes, it pulls from your batteries or the grid automatically — you don't have to lift a finger. And when the grid goes down, your home keeps running.
That's the quiet confidence of a hybrid system. You don't have to cut the cord entirely unless you want to. You're simply taking back control of how your home is powered, and how much you hand over each month.
There's a lot of engineering behind that simplicity.
Three MPPTs and a 600V DC input let you bring in up to 18kW of solar with tidier, more efficient wiring. The EG4 18kPV talks directly to your 48V EG4 batteries through closed-loop communication, and works with lithium or lead-acid banks. Line balancing, arc-fault and ground-fault protection, an integrated PV disconnect and a surge protection device are all built in. It's even EMP-hardened, for peace of mind against the kind of disruption most systems never plan for.
Want to keep an eye on everything? Built-in Wi-Fi connects you to EG4's app, so you can watch your solar yield, battery levels and grid use — and even update firmware — from anywhere.
The EG4 18kPV in a nutshell:
-
Three modes in one — off-grid, grid-tied and grid-assist, so your system adapts to your goals and your utility's rules.
-
3 MPPTs, 600V DC input — brings in up to 18kW of solar efficiently, with simpler, lower-cost cabling.
