EG4 Solar Solutions

EG4 Inverters, Batteries & Solar

EG4 has become one of the most popular names in home and off-grid energy, and Krato Power carries the full lineup: hybrid and off-grid inverters, LiFePO4 batteries, power management, and EG4's solar-assisted mini-split air conditioners. Whether you are building whole-home backup, going off-grid, or expanding a system you already own, we help you match every piece so it works together.

EG4 inverters

From the compact 3000 EHV and the off-grid 6000XP and 12000XP to the hybrid FlexBOSS18, FlexBOSS21, 12kPV, and whole-home 18kPV, EG4 inverters manage solar, battery, grid, and generator in one unit. Tell us your loads and we will size the right one.

EG4 batteries

Scalable LiFePO4 storage: LL-S and LifePower4 server-rack batteries, indoor and all-weather WallMount batteries (14.3 kWh and 16 kWh), and pre-assembled battery cabinets and racks for backup that lasts from a few hours to whole-home, multi-day.

EG4 solar mini-split air conditioners

Cool efficiently on solar with EG4's hybrid mini-splits: 9K, 12K, 24K, and 36K multizone units, plus a 12,000 BTU hybrid solar window unit. Ideal for off-grid cabins, shops, and cutting one of the biggest loads in the home.

Power management & accessories

Round out your build with the EG4 GridBOSS for microgrid and load management, the Chargeverter for fast AC charging, MPPT charge controllers, BrightMount racking, and PowerPro conduit boxes and cables.

Design your system with us

EG4 is a system, not a single box. Tell us your goal, your loads, and your budget, and we will build a complete, compatible EG4 parts list. Shop below, or contact our team for free system design.
