About the Felicity Solar IVGM18KLP3G1 18kW Three-Phase Hybrid Solar Inverter
The Felicity Solar IVGM18KLP3G1 is an 18 kW three-phase hybrid solar inverter: 18 kW rated and 18 kVA of rated apparent power, peaking at 19.8 kVA on a 380-400 V line, at up to 97.6% maximum efficiency. It takes 28.8 kW of PV across two MPPT trackers and moves up to 330 A into or out of a 40-60 V battery bank, with the full 18 kW available on backup after a 20 ms transfer. Each tracker runs 160-650 V and accepts 2+2 strings and 36+36 A of PV input current under an 800 V ceiling, tracking at full load from 500 V to 800 V. AC output current is 26.1 A rated and 28.7 A maximum, with 70 A of pass-through and a 10-second surge to twice rated power. Two battery inputs talk RS485 or CAN to the BMS, and the charge algorithm self-adapts to it, so lithium-ion and lead-acid both work. The IP65 smart-cooled enclosure measures 750 x 450 x 268 mm, runs from -25 C to 60 C with derating above 45 C, and is certified to IEC 62109-1, EN 62109-1, IEC 62109-2 and EN 62109-2. We supply it as an authorised Felicity Solar distributor.
