Felicity Solar IVGM30KHP3G230kW three-phase high-voltage hybrid inverter, two battery inputs

Overview

IVGM30KHP3G2 is the 30kW member of the IVGM25~50kW-P3G2 series, a three-phase hybrid inverter for high-voltage LFP batteries. It has three MPP trackers of 36A, takes up to 48kW of PV input power (60kW connected) and reaches full output from 444V. Its two independent battery inputs, 160–800V and 50A each, can serve two separate clusters. Rated output is 43.5A per phase, with 33kW maximum, 200A grid pass-through and up to 12 units in parallel.

• 25–50kW three-phase output, 3L+N+PE
• Two independent battery inputs, 160–800V, 50A each
• Up to four MPPT, 1000V maximum PV voltage
• 200A grid-to-load pass-through, switchover under 10ms
• Up to 12 units in parallel
• IP65, -40…+60°C, 10-year warranty

How it works

The IVGM25~50kW-P3G2 inverters manage PV, a high-voltage lithium battery, the grid and a generator from one wall-mounted cabinet. The GRID terminal carries the utility connection and non-essential loads, LOAD feeds the protected circuits and GEN accepts a generator. Each phase is controlled independently, so the manufacturer states the unit can deliver three-phase power to loads even where the incoming supply is single-phase.

Two battery inputs, BAT1 and BAT2, each accept up to 50A within 160–800V and have their own BMS port. Two separate battery clusters can therefore run side by side without circulating current, or one bank can be wired to both inputs with the Parallel bat1 & bat2 option enabled. The battery type is LFP only.

Key features

PV strings connect through two to four MPP trackers depending on the model, each taking 36A with two strings per tracker, a 1000V maximum input and a 150–850V MPPT range; up to 1.6 times PV oversizing is supported. Off-grid, the output can deliver 1.5 times rated power for 10s. The manual gives 97.6% maximum and 97.0% European efficiency, and the series supports Time of Use, Selling First and zero-export modes.

Installation and compatibility

The cabinet measures 940×582×340mm and weighs 87.1kg, so it needs a load-bearing non-combustible wall with 500mm clearance at the sides and 450mm above and below, out of direct sun and rain. The manual states it must be installed in non-residential areas. Felicitysolar specifies a 200A DC breaker per battery input, 16mm² battery cable and 240A AC breakers on the grid and backup sides, based on the 200A pass-through rating.

Grid documents published for the series include a Europe-wide EN 50549-1/-10 attestation and a VDE-AR-N 4105 certificate, and the datasheet also lists CEI 0-21, UNE 217001/217002 and G99. Up to 12 inverters can be paralleled; in a parallel system the CTs or smart meter are connected to the master unit.

Monitoring and settings

An LCD touch screen gives access to battery, grid, generator and work-mode settings, including Zero Export to Grid Port and Zero Export to CT with three split-core CTs. The GEN port can be programmed for a generator, a smart load or microinverters, and a dry contact can start a generator automatically. A Wi-Fi or GPRS module links the inverter to the Fsolar cloud platform for remote monitoring.
