Can 100/20 handle a 285W panel producing 36V?

Hi just installed a single 285W solar panel on my camper and on first reading I saw that it’s producing 36V....


is this OK for the 100/20 controller? I’m storing onto a AGM 210Ah leisure battery. Is this controller OK for this panel?


I’ve looked at the app setting and I only have 12/24V options with currently 12V on.

Is this OK?

Thanks

The specifications of the BlueSolar MPPT controller are available here: https://www.victronenergy.com/upload/documents/Datasheet-Blue-Solar-Charge-Controller-MPPT-75-10,-75-15,-100-15-&-MPPT-100-20-EN-.pdf

The maximum Voc (open circuit voltage) for the 100/20 is 100V and a maximum Isc (short circuit current) of 20A - these specifications should be listed with your panel.

12/24V relates to the battery voltage attached to the charger, not the voltage of the panels attached to the charger - it's important to set this correctly according to your battery.
