About the Felicity Solar T-REX-3K6LP1G01 3.6kW Single-Phase Hybrid Solar Inverter

The Felicity Solar T-REX-3K6LP1G01 is a single-phase hybrid solar inverter rated 3.6 kVA and 3.6 kW at 230 V, delivering 15.6 A rated and 19.5 A maximum output current at up to 97.5% efficiency, with two MPPT trackers that accept a recommended 4.7 kW of solar panels. European efficiency is 96.7% and MPPT efficiency 99.9%. Each tracker runs from 100-500 V, or 160-500 V at full load, takes 15+15 A and starts at 130 V, under a 550 V maximum PV input. A single 40-60 V battery input charges and discharges lead-acid or Li-Ion packs at up to 100 A and 3.6 kW, self-adapting to the pack's own BMS over RS485 or CAN. Grid failure transfers to backup in 20 ms, holding 3.6 kW and 30 A. The isolated, transformer-based unit is IP65, naturally cooled, wall-mounted at 530 x 493 x 228 mm and 32.4 kg, parallels to six units, and is certified to IEC 62109-1 and IEC 62109-2. We are an authorised Felicity Solar distributor and supply the T-REX-3K6LP1G01 from our own stock. Warranty: 2 Years.

Frequently Asked Questions

3.6 kW — the T-REX-3K6LP1G01 is rated 3.6 kVA and 3.6 kW at 230 V single phase on 50/60 Hz, giving 15.6 A rated and 19.5 A maximum output current. Peak efficiency is 97.5%, European efficiency 96.7%, and surge capacity is twice rated power for 10 s.

4.7 kW is the maximum recommended PV power, split across two MPPT trackers carrying one string each. Each tracker accepts 15+15 A, or 18+18 A on short circuit, and works from 100-500 V — 160-500 V at full load — starting at 130 V and never exceeding a 550 V maximum PV voltage.

40-60 V lead-acid or Li-Ion packs on its single battery input, charged and discharged at up to 100 A and 3.6 kW. The charge algorithm self-adapts to the pack's own BMS over RS485 or CAN, and the grid can charge the same bank at up to 100 A through a 40 A maximum AC input.

20 ms. Backup output is rated 3.6 kW with a 30 A maximum output current at 230 V, the same 30 A that is the maximum AC pass-through. Anti-islanding, GFCI, insulation resistance detection and ground fault current monitoring are all built in.
