About the Felicity Solar T-REX-50KHP3G01 50kW Three-Phase Hybrid Solar Inverter

The Felicity Solar T-REX-50KHP3G01 is a 50 kW three-phase hybrid inverter that accepts 65 kW of PV across four MPPT trackers, delivers 55 kW of maximum AC output at up to 79.7 A, backs up 50 kW of load, and runs a 160-800 V LFP battery bank. Each tracker takes 36 A of string current and works from a 250 V start-up across a 200-850 V window, nominally 600 V, above a 150 V minimum DC input and below 1000 V maximum PV voltage. Grid wiring is 3L+N+PE/3L+PE at 220-230 V and 50/60 Hz, with 97.6% peak, 97% European and 99.9% MPPT efficiency, THD under 3% and a 10 ms transfer time. Two battery inputs charge and discharge at 50+50 A. A 3.5-inch LCD touch screen and WiFi/GPRS monitoring watch the unit, RS232 and RS485 carry data and RS485 and CAN reach the BMS. The IP65 Smart Cooling body is wall-mounted, 85.6 kg net and 98.4 kg gross, shipped as 1110 x 770 x 463 mm, and rated -25 to 60 °C. We are an authorised Felicity Solar distributor; the T-REX-50KHP3G01 is covered for 2 Years.
