In case the above step is not possible, measure the battery and PV voltages at the solar charger terminals using a multi meter instead. Compare both voltages. The PV voltage needs to be a minimum of 120V to start up, and also 80V to continue operation. Causes of zero or low PV voltage: Not enough solar irradiance into the solar panels: Night.
In case the PV array is located in cold climates or if the night temperature drops close to or below 10°C the PV array can output more than its rated Voc. As a rule of thumb, keep an additional 10% safety margin. An overvoltage event can damage the solar charger, depending on how much the maximum PV voltage was exceeded.
The maximum bulk time protection is a feature that was in the chargers when they were just released (2015 or earlier) and later the feature was removed. If you do see this error, then update to the latest firmware. If you then still have the error, perform a reset to factory defaults of the configuration, and reconfigure the solar charger.
Error 43 - Inverter shutdown (Ground Fault) The voltage difference between Neutral and Ground is too high. Inverter or Multi (not connected to the grid): The internal ground relay is activated but the voltage over the relay is too high. The relay might be damaged. Multi (connected to the grid):
AC Chargers This protection is default enabled on the Skylla-i and the Skylla IP44. This error is generated when the battery-absorption-voltage is not reached after 10 hours of charging. The feature of this safety protection is to detect a shorted cell; and stop charging.
The PV voltage should never exceed the maximum rated PV voltage of the solar charger. The maximum PV voltage rating is printed on the front or on the side of the housing of the controller, and in the product specification sheets. The solar charger stops charging if the PV voltage exceeds the maximum rated PV voltage.
