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.
