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.

Sana'a sits above 2,000 metres, and an inverter whose datasheet permits 2,000 m is not rated for the city at all. Here is the altitude row on 44 Felicity listings, model by model, and which ones cover your elevation.
Read: Which Solar Inverters Actually Work in Sana'a? →Twenty-five Felicity inverters are IP21 and every SCCM charge controller says indoor wall-mount. IP20, IP21 and IP31 are indoor ratings, and the first digit - the dust one - is the half nobody reads. Here is which listing carries which.
Read: Can I Install a Solar Inverter Outside? What IP21, IP31 and IP65 Really Mean →An off-grid house is sized by surge, battery energy and charge current - and the surge row is the one that starts your fridge and your pump. Here are the published figures across the Felicity inverters and batteries, with the arithmetic to use them.
Read: How to Run a Whole House on Solar in Khartoum →65 kW. The T-REX-50KHP3G01 spreads it across four MPPT trackers rated 36+36+36+36 A, tracking between 200-850 V from a 250 V start-up, nominally 600 V, above a 150 V minimum DC input and below 1000 V maximum PV voltage.
50 kW rated and 55 kW at maximum, up to 79.7 A, three phase on 3L+N+PE/3L+PE wiring at 220-230 V and 50/60 Hz, at 97.6% peak and 97% European efficiency, THD under 3% and a 1.5*rated (10s) surge rating.
160-800 V. LFP banks in that window, on two battery inputs that charge and discharge at 50+50 A and talk to the BMS over RS485 and CAN, backing 50 kW of load with a 10 ms transfer time.
85.6 kg net and 98.4 kg gross, shipped as a 1110 x 770 x 463 mm package, wall-mounted and rated IP65 with Smart Cooling for -25 to 60 °C with derating above 50 °C and altitudes to 3000 m with derating above 2000 m. It is certified to IEC 62109-1, EN 62109-1, IEC 62109-2 and EN 62109-2. We are an authorised Felicity Solar distributor; it is covered for 2 Years.
