Hybrid Inverter
The EG4® FlexBOSS18 is a 13kW, 120/240VAC split-phase, all-in-one hybrid sine wave inverter, designed for residential and small commercial applications. It supports up to 18kW (STC)
of solar PV input across two MPPTs (26A each) and can deliver 10kW of continuous power from the battery or 13kW with solar PV assistance when grid-connected. The FlexBOSS18
also features a 90A grid bypass capability, allowing seamless power flow from the grid to connected loads. As the more affordable, entry-level counterpart to the FlexBOSS21, the FlexBOSS18 offers a powerful solution
for energy independence. While fully capable as a standalone inverter, it is optimized for use with EG4’s GridBOSS power gateway, unlocking enhanced functionality and performance for the end user.
