Why is my Victron Energy Controller battery not fully charged?

  Tyler WalterAug 9, 2025
  Several factors can prevent your Victron Energy Controller from fully charging the battery. It could be due to: * A bad battery connection: Check the battery connection. * Cable losses being too high: Use cables with a larger cross-section. * A large ambient temperature difference between the charger and the battery: Ensure that ambient conditions are equal for the charger and battery. * For a 24V or 48V system: The wrong system voltage being chosen (e.g., 12V instead of 24V) by the charge controller: Disconnect the PV and battery, then reconnect the battery first. Make sure that the battery voltage is higher than 17.5V (24V system) or 35V (48V system).

  If your Victron Energy Controller charger isn't working, it might be due to a reversed PV connection. To solve this, connect the PV correctly. Another potential cause is a reverse battery connection, which could blow a non-replaceable fuse, requiring you to return the unit to VE for repair.

  If your Victron Energy Controller is overcharging the battery, it could be because a battery cell is defective, in which case you should replace the battery. Another cause might be a large ambient temperature difference between the charger and the battery. To resolve this, make sure that ambient conditions are equal for the charger and battery.

How to fix LCD display on Victron energy SmartSolar MPPT 150/100 if it doesn't light up?
- J
  James WallsSep 1, 2025
  If the LCD on your Victron Energy Controller isn't lighting up, it's possible that the internal power supply isn't getting enough power. This supply relies on either the solar array or the battery. If both the PV and battery voltage are below 6V, the LCD won't light up. Make sure that the LCD display is properly inserted into the socket.
