Felicity 61.44kWh high-voltage rack storage kit – 50kW three-phase hybrid
This is not a pairing of ours: 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 make 61.44kWh at 614.4V, with the 50kW IVGM50KHP3G2 inverter in front.
The numbers line up: the inverter's battery window runs from 160 to 800V, the twelve modules work between 556.8 and 691.2V, and the two 50A inputs give 61.4kW of charge and discharge, more than the inverter's rating. A little over an hour at full power, or a whole night at reduced load.
The rack ships ready to assemble with twelve bays plus the BMS bay, so the configuration is right from the start: no modules left over, no mixed generations. LiFePO4 cells, over 6,000 cycles, 90% depth of discharge, ten years of warranty. Panels and protection boards are not included.
