Felicity Solar high-voltage rack storage kit 61.44kWh – IVGM50KHP3G2 50kW three-phase hybrid inverterIVGM50KHP3G2 50kW inverter with twelve FLH48100UMG2 rack modules at 614.4V

Overview

This is not our own combination: it is the system Felicity publishes in its commercial and industrial datasheet, “IVGM 50kW inverter & FLH 61kWh HV LFP battery”. Twelve 5.12kWh FLH48100UMG2 modules, the FLH48100UCG2 control module and the FLH48100R13 rack give 61.44kWh at 614.4V in front of the IVGM50KHP3G2 50kW inverter. The inverter's battery window runs from 160 to 800V, the twelve modules work between 556.8 and 691.2V, and two 50A inputs give 61.4kW of charge and discharge: just over an hour at full power, or a whole night at reduced load. PV modules and protection boxes are not included.

• Inverter and battery from the same maker, native CAN
• 48V kits: 8kW single-phase, 12, 15 and 20kW three-phase
• High-voltage kits: 30kW with 30.72kWh, 50kW with 61.44kWh
• PV versions with Trina Solar Vertex S+ 505W modules and protection boxes
• Switch-over to backup in under 10ms
• 10-year warranty on inverter and batteries

What's in the kit

• 1 × Felicity Solar IVGM50KHP3G2 Hybrid inverter
• 12 × Felicity Solar FLH48100UMG2 Battery module
• 1 × Felicity Solar FLH48100UCG2 Control module (BMS)
• 1 × Felicity Solar FLH48100R13 Rack cabinet

How the kits are built

The combinations follow Felicity's official datasheets: each inverter is paired with batteries whose current and voltage fit its battery input, and the 50kW kit with 61.44kWh is the system Felicity itself publishes. The PV versions add Trina Solar Vertex S+ 505W modules in strings sized for the inverter, plus the AC and DC protection boxes.

Low or high voltage

The 48V kits use floor-standing Felicity batteries that can be paralleled up to fifteen units, so storage grows one battery at a time. Above twenty kilowatts the high-voltage kits run at 614.4V: the same power flows with a quarter of the current, with heated IP65 modules in the 30kW kit and a rack cabinet in the 50kW kit.
