The T-REX-6KLP1G01 puts 6 kW through a 230 V single-phase output rated 26 A, moves 120 A into and out of a 40-60 V bank, and is rated to work at up to 2000 m.
In stock
The Felicity Solar T-REX-6KLP1G01 is a 6 kW single-phase hybrid solar inverter that accepts 7.8 kW of recommended PV power on two MPPT trackers, moves 120 A into and out of a 40-60 V battery bank, and delivers 6 kW and 6 kVA at 230 V at 97.6% maximum and 97% European efficiency. Each tracker carries one string from a 130 V start-up, works between 100 and 500 V, holds full load from 260 to 500 V around a 360 V rated PV input voltage, and takes 15+15 A of input current and 18+18 A of short-circuit current up to 550 V. The AC side is L+N+PE, rated 26 A, 30 A at maximum and 30 A in backup behind the 6 kW backup output, with a 20 ms transfer, twice rated power for 10 seconds, THD under 3% and a power factor above 0.99. AC charging also reaches 120 A from a 184-264.5 V input drawing 40 A. The isolated, transformer-based chassis is IP65, 530 x 493 x 228 mm and 32.4 kg net, rated to 2000 m. We are an authorised Felicity Solar distributor and supply the T-REX-6KLP1G01 from our own stock, with a 2 Years warranty.

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 →On IVPS/IVPM models, continuous beep + solid red = fault, output cut; intermittent beeping + flashing red = warning. The number on the LCD is the fix.
Read: Felicity Inverter Beeping? What the Beeps & Red Light 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 →7.8 kW is the maximum recommended PV power, split over two MPPT trackers with one string each. They take 15+15 A of input current and 18+18 A of short-circuit current, track from 100 to 500 V after a 130 V start-up, hold full load from 260 to 500 V around a 360 V rated PV input voltage, and accept up to 550 V, with a 90-550 V PV working range at 99.9% MPPT efficiency.
120 A is the maximum charging current, the maximum discharging current and the maximum AC charging current alike, into a single battery input covering 40-60 V, for 6 kW of maximum charge and discharge power. Lead-Acid and Li-Ion are supported, and the charge algorithm self-adapts to the BMS over RS485 and CAN.
6 kW rated output power and 6 kVA rated apparent output power, single phase at 230 V on L+N+PE wiring, with 6 kW of maximum AC output power. Rated output current is 26 A, maximum output current 30 A and backup output current 30 A, with a 20 ms transfer time, twice rated power for 10 seconds, THD under 3%, a power factor above 0.99 and 97.6% maximum efficiency. Input runs 184-264.5 V at up to 40 A, 50/60 Hz across 45-55 Hz and 55-65 Hz windows.
The IP65 wall-mounted chassis measures 530 x 493 x 228 mm, weighs 32.4 kg net and 39.1 kg gross, is intelligently air-cooled and runs from -25 to 60 °C with derating above 45 °C, to 2000 m of altitude and 0-100% humidity. It reports over WiFi or GPRS with RS232 and RS485 interfaces and an LCD and LED panel, parallels to 6 units, and carries a 2 Years warranty.
