EG4 Hybrid and Off-Grid Inverters
Solar charging, battery charging and AC output in one box. The hybrids back up a grid-tied home, and the XP series runs cabins, shops and homes with no utility at all.
Compare EG4 Inverters
Start with how your home connects. If you have utility service and want backup power, plus solar export where your interconnection agreement allows it, go hybrid. If there's no utility line, or you'd rather not depend on one, the 6000XP and 12000XP run with no grid connection and can use a generator as their charging source.

Need 12kW Off-Grid Now? Parallel Two 6000XPs
EG4 rates the 6000XP for parallel operation with up to 16 units. Two of them give you 12kW of 120/240V output and 16kW of solar input across four MPPTs, which also makes it easier to split arrays across roof faces or a ground mount. Add units later as your loads grow.

EG4 Inverter FAQ
Yes, on most models. EG4 rates the 18kPV for up to 10 units (120kW total), and the 6000XP and 12000XP for up to 16 units each (96kW and 192kW).
EG4 backs the FlexBOSS21, FlexBOSS18 and 18kPV with a 10-year warranty, and the 6000XP and 12000XP with 5 years.
Yes. The 12000XP takes up to 63A from a generator, and the FlexBOSS21 adds generator support, AC coupling and smart loads when you pair it with the GridBOSS. To charge your bank straight from a generator without routing that power through the inverter, add a Chargeverter-GC, a 48V, 100A charger with auto generator start.
Yes. All five carry UL 1741, and the 18kPV is listed to UL 1741 SB. The FlexBOSS21 and FlexBOSS18 also carry UL 3141. For a permitted battery system, EG4 publishes UL 9540 certificates for specific inverter and battery pairings, so order the exact pairing named on the certificate.
EG4 states the 18kPV works with 48V EG4 batteries and other battery brands. Closed-loop communication depends on the battery protocol, so check your exact battery with our team before you order.
