Why is my SMA SUNNY BOY 4000TL waiting for DC start conditions (Event 3901 to 3902)?
If your SMA Inverter displays 'Waiting for DC start conditions' (Event 3901 to 3902), the input power or voltage of the PV modules is not yet sufficient for feeding into the electricity grid. Wait until irradiation is higher. If this event recurs at medium irradiation levels, check the PV plant design and the correct circuitry of the PV array.
