Hybrid or Off-Grid: Which EG4 Inverter?
Hybrid: 18kPV, 12kPV, and FlexBOSS
Hybrid inverters work with the grid. They run your home on solar and battery, back it up when the grid goes down, and can send extra solar back to the utility where your interconnection agreement allows it.
Off-grid: 6000XP and 12000XP
Off-grid inverters run without a utility connection. They can still use the grid or a generator as a charging input, but they don’t export power, which keeps cabins, shops, and remote homes simple.
Either way, pair the inverter with EG4 batteries that are listed with it if you’re pulling a permit. Our UL 9540 page explains why that matters.

EG4 FAQ
If you want to stay grid-tied with battery backup, look at the hybrids: the 18kPV, 12kPV, and FlexBOSS. For homes and cabins with no utility connection, the 6000XP and 12000XP run fully off-grid and can still charge from a generator. Contact our support team and we’ll help you size it.
Many EG4 inverters and batteries carry UL 9540 as listed combinations, such as the LifePower4 V2 with the 18kPV. Check each product page for its listed pairings.
A 48V battery charger that runs from a generator or the grid, so you can charge your bank directly instead of routing that power through the inverter. The Chargeverter-GC adds automatic generator start.
EG4 batteries communicate over CAN and RS485 for closed-loop operation with EG4 inverters and many other major brands. Ask our team to confirm a specific pairing before you order.
