27. nergy the system is designed with maximum power point tracking MPPT control namely the system will regardless of sunshine and temperature constantly maintain solar cell array output under maximum power state Standby Standby state means that when PV array output voltage is up to a certain value but fails to comply with startup condition while parameters such as grid voltage and frequency are within allowable range Under the mode inverter will constantly detect 28 open circuit voltage of PV array and when larger than 320V enter startup state Sleep Sleep state means the state under which PV array has the output voltage less than 200V fails to support auxiliary power supply but power grid functions normally When system detects the output voltage of PV array less than 200V and no demand for SVG in night it will automatically enter sleep state to reduce system energy consumption Normal shutdown or fault Normal shutdown or fault means the specific state under which the system would protect itself when PV array has low output power or suffers shutdown failure When PV array has quite low output power less than 100W in consecutive 5 minutes and no demand for SVG in night the system will enter shutdown mode To manually shut down the equipment on display screen you have to connect with power grid again via display screen When the system failure is detected the system will under no circumstances disconnect the inver
