The SUNT-12.0kW-HT is the most powerful single-phase inverter in Lumentree's indoor range. It accepts up to 19.2 kW of panels on two MPPTs, charges the battery at up to 220 A and delivers 12 kW continuously with 24 kVA peaks for heavy starts. The Smart Load output lets selected loads (such as a water heater or pump) run only on solar surplus.
Large homes, workshops, farms and single-phase commercial premises, including generator systems.
