The maximum recommended solar panel power depends on the battery system you are using: 12V battery system: up to 650W of solar panels 24V battery system: up to 1300W of solar panels Please also ensure that the total open-circuit voltage (Voc) of the solar panel array does not exceed 100V DC, which is the controller's maximum PV input voltage. If this answer does not resolve the current issue, please contact us again for assistance.
