EG4 is an American solar equipment brand headquartered in Sugar Land, Texas, developed by the Signature Solar group. The company builds all-in-one off-grid and hybrid inverters for the North American 120/240 V split-phase market alongside its server-rack LiFePO4 batteries. The flagship 18kPV-12LV hybrid inverter delivers 12 kW of AC output from up to 18 kW of PV across three MPPT inputs at up to 600 V, while the 6000XP and 12000XP off-grid line accepts strings up to 480 V and parallels up to 16 units. EG4 equipment is certified to UL 1741 and UL 9540 and has become a favourite of the North American DIY solar community for its closed-loop battery communication and accessible pricing.
