Felicity Solar T-REX-5KLP1G01 5kW Single-Phase Hybrid Solar Inverter features

6.5 kW of PV across two MPPT trackers

Maximum recommended PV power is 6.5 kW on a 5 kW inverter, split over two MPPT trackers that take 15+15 A of input current and 18+18 A of short-circuit current, one string each, up to a 550 V maximum PV voltage.

100-500 V MPPT window from a 130 V start-up

Tracking opens at a 130 V start-up voltage, runs from 100 to 500 V, holds full load from 220 to 500 V and works across a 90-550 V PV range around a 360 V rated PV input voltage, at 99.9% MPPT efficiency.

100 A charging and 100 A discharging on one battery input

Maximum charging current and maximum discharging current are both 100 A into a 40-60 V bank on a single battery input, for 5 kW of maximum charge and discharge power, with Lead-Acid and Li-Ion supported by a charge algorithm that self-adapts to the BMS over RS485 and CAN.

5 kVA single-phase output, 21.7 A rated and 25 A maximum

Rated apparent output power is 5 kVA at 230 V on L+N+PE wiring, with a 21.7 A rated output current, a 25 A maximum output current and 30 A in backup, a surge of twice rated power for 10 s, and a power factor above 0.99 adjustable from 0.8 leading to 0.8 lagging.

97.6% maximum efficiency and a 20 ms transfer time

Maximum efficiency is 97.6% and European efficiency 97%, THD stays below 3%, and the 20 ms transfer sits behind anti-islanding protection, GFCI protection, insulation resistor detection, ground fault current monitoring and certification to IEC 62109-1 and IEC 62109-2.

530 x 493 x 228 mm IP65 chassis, 6 units in parallel

The wall-mounted, naturally cooled IP65 unit measures 530 x 493 x 228 mm and weighs 32.4 kg net and 39.1 kg gross in a 632 x 570 x 315 mm carton, works from -25 to 60 °C with derating above 45 °C and up to 2000 m, and parallels up to 6 units. Supplied with a 2 Years warranty.

About the Felicity Solar T-REX-5KLP1G01 5kW Single-Phase Hybrid Solar Inverter

The Felicity Solar T-REX-5KLP1G01 is a 5 kW single-phase hybrid solar inverter that accepts up to 6.5 kW of PV across two MPPT trackers, charges and discharges a 40-60 V battery bank at 100 A, and delivers 5 kVA at 230 V with a maximum efficiency of 97.6%. Each tracker carries one string, starts at 130 V, tracks from 100 to 500 V, holds full load from 220 to 500 V and takes 15+15 A up to the 550 V maximum PV voltage. AC output is 230 V on L+N+PE wiring, rated at 21.7 A, peaking at 25 A and at 30 A in backup, with THD below 3% and a 20 ms transfer time. The single battery input takes Lead-Acid and Li-Ion, self-adapting to the BMS over RS485 and CAN, and AC charging also reaches 100 A from a 184-264.5 V input drawing up to 40 A. European efficiency is 97% and MPPT efficiency 99.9%. The naturally cooled IP65 chassis measures 530 x 493 x 228 mm, weighs 32.4 kg net, runs from -25 to 60 °C and parallels up to 6 units. We are an authorised Felicity Solar distributor and supply it with a 2 Years warranty.
