6.5kW | Single Phase | 2 MPPT
The single-phase inverter is one of the best options for residential application thanks to its smaller size and local LCD display, buttons. Also, with built-in zero-export function (external CT is needed), it offers true ease and comfort for PV system operators and installers.
