At 240V split-phase output, HESP48120U200-H is rated at 12,000W. In the 120/208Vac three-phase configuration, SRNE lists rated output at 10,400W and peak output at 20,800W. That is why a 12kW hybrid inverter should be evaluated according to the actual AC topology, not only the model name. Installers planning a three-phase configuration should use the output values for that configuration when calculating load capacity and system headroom.
