This property has a three phase power supply running two large hydronic heat-pumps for central heating, though the majority of other electrical loads are single phase. The Infinite Energy team designed and installed a system using a grid connected three phase inverter, as well as a single phase hybrid/battery inverter. The home stores energy for evening use on the major single phase circuits, while it powers the under-slab heating from the three phase inverter. During a power cut, the home has all single phase critical loads backed up from a 13kWh lithium battery set up.
