The DC-AC conversion circuit converts the DC power into AC power and feeds it into the grid,
complying with requirements of local regulations.
The insulation relay disconnects the inverter from the electrical network when the grid or the
inverter fails.
The LC filter filters the over-frequency components coming from the AC output of the inverters to
ensure that the energy fed into the grid meets the quality requirements of the grid itself.
AC surge arresters (category III, category II added on S5 models) provide overvoltage discharge to
the AC side in order to protect the internal circuits of the inverters again excessive AC voltages.
The communication board allows the inverter to communicate via RS485 and Wi-Fi (optional); the
user can access all operating data via web portal from a PC and via APP.
