Application: 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.

Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in the UAE that rests with the local authorities (DEWA, ADDC, SEWA). Confirm the grid code, import requirements and any local certification with them, or with us, before you order.

Frequently Asked Questions

How much power does the T-REX-3K6LP1G01 deliver?

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.

How many solar panels can the T-REX-3K6LP1G01 take?

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.

Which batteries work with the T-REX-3K6LP1G01?

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.

How quickly does the T-REX-3K6LP1G01 switch to backup?

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.

How much solar can I connect to the T-REX-3KLP1G01?

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.

What output does the T-REX-3KLP1G01 deliver?

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.

Which batteries does it charge, and how fast?

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.

How large is the T-REX-3KLP1G01 and where is it installed?

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.

How much solar can the T-REX-4K6LP1G01 take?

Up to 6 kW of PV is the maximum recommended array for the T-REX-4K6LP1G01. Its two MPPT trackers accept 550 V and 15+15 A, work from 100-500 V and from 200-500 V at full load, and start tracking at 130 V.

How fast does the T-REX-4K6LP1G01 charge and discharge a battery?

100 A is the maximum charge and discharge current of the T-REX-4K6LP1G01, across a 40-60 V lead-acid or Li-Ion bank on its single battery input. Charge and discharge power is capped at 4.6 kW, and the charge algorithm self-adapts to the battery BMS over RS485 or CAN.
