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.

Frequently Asked Questions

What is the rated output of the Felicity IVGM18KLP3G1?

The IVGM18KLP3G1 is rated at 18 kW with 18 kVA of rated apparent power and 19.8 kVA maximum, delivered as three-phase 380-400 V line voltage (220-230 V per phase) on 3L+N+PE wiring at 50/60 Hz. Rated output current is 26.1 A and maximum output current 28.7 A, with 92 A of overcurrent protection and a surge to twice rated power for 10 seconds. Backup rated output power is also 18 kW.

How large a solar array can the IVGM18KLP3G1 take?

Up to 28.8 kW of PV, split across two MPPT trackers taking 2+2 strings. Each tracker works from 160 V to 650 V, with full-load tracking from 500 V to 800 V, an 800 V maximum PV voltage, 550 V rated PV input voltage and 36+36 A of input current (54+54 A short-circuit). The inverter starts up at 160 V and reaches 97.6% maximum efficiency.

Which batteries does the IVGM18KLP3G1 support, and how fast does it charge?

It has two battery inputs for lead-acid or lithium-ion banks in the 40-60 V range, charging and discharging at up to 330 A. BMS communication runs over RS485 or CAN and the charge algorithm self-adapts to the BMS, so a compatible lithium pack sets its own charge profile. Transfer to backup takes 20 ms.

What size is the IVGM18KLP3G1, and where can it be installed?

The inverter itself measures 750 x 450 x 268 mm and weighs 48.7 kg net, 60.2 kg gross in its packaging. It is IP65-rated with smart cooling and operates from -25 C to 60 C, derating above 45 C. A DC switch, AFCI and ground fault current monitoring are built in, and up to 10 units can be paralleled.
