About the Felicity Solar T-REX-3KLP1G01 3kW Single-Phase Hybrid Solar Inverter

The Felicity Solar T-REX-3KLP1G01 is a 3 kW single-phase hybrid inverter that holds a 16.3 A maximum output current at 230 V, reaches 97.5% peak and 96.7% European efficiency, and accepts up to 3.9 kW of recommended PV power across two MPPT trackers working from 100-500 V. On the array side it takes 40 A of PV input current and 550 V maximum PV voltage, starts up at 130 V, is rated at 360 V, and tracks at 99.9% efficiency. One battery input covers 40-60 V for Lead-Acid or Li-Ion packs, charging and discharging at up to 100 A with a charge algorithm that self-adapts to the BMS over RS485 or CAN. Backup output is rated 3 kW and 30 A with a 20 ms transfer time, under 3% total harmonic distortion and a power factor above 0.99. The wall-mounted enclosure is IP65 and naturally cooled, weighs 32.4 kg net, runs from -25 to 60 °C with derating above 45 °C, parallels to 6 units and is built to IEC 62109-1 and IEC 62109-2. We are an authorised Felicity Solar distributor and supply the T-REX-3KLP1G01 from our own stock. Warranty: 2 Years.

Frequently Asked Questions

3.9 kW is the maximum recommended PV power. Two MPPT trackers run from 100-500 V (140-500 V at full load) and 90-550 V working range, accept 40 A of PV input current with 18+18 A of short-circuit current, and tolerate 550 V maximum PV voltage. Each tracker takes one string, start-up begins at 130 V and rated PV input voltage is 360 V.

16.3 A is the maximum output current at 230 V single-phase, above the 13 A rated output current, for 3 kW of rated and maximum AC output power. Backup output is 3 kW at 30 A with a 20 ms transfer time and a surge rating of 2*rated (10s), at under 3% total harmonic distortion and a power factor above 0.99.

100 A is both the maximum charge and the maximum discharge current, on one battery input covering 40-60 V for Lead-Acid or Li-Ion packs, with 3 kW of maximum charge/discharge power. The charge algorithm self-adapts to the BMS over RS485 or CAN, and AC charging also reaches 100 A from a 40 A maximum AC input current.

530 x 493 x 228 mm is the unit's own size, at 32.4 kg net; packed it is 632 x 570 x 315 mm and 39.1 kg gross. It is wall-mounted with an IP65 enclosure and natural cooling, works from -25 to 60 °C with derating above 45 °C, 0-100% humidity and up to 2000 m altitude, and is monitored over WiFi/GPRS with an LCD and LED display.
