If your Victron Energy Controller is not fully charging the battery, several factors could be at play. A poor battery connection might be the cause, so check the connection. High cable losses can also prevent a full charge; consider using cables with a larger cross-section. Additionally, a significant temperature difference between the charger and battery could be the issue; ensure the ambient conditions are similar for both. Finally, for a 24V system, make sure the correct system voltage (24V instead of 12V) is selected by the charge controller; disconnect the PV and battery, ensuring the battery voltage is above 19V, then reconnect properly.

If your Victron Energy Controller is overcharging the battery, it could be due to a defective battery cell, 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 charger and battery.

The Victron Energy Controller charger might not be functioning due to a reversed PV connection. In this case, connect the PV correctly. Another cause may be that no fuse is inserted; make sure to insert a 20A fuse.

If the Victron Energy Controller battery isn't fully charged, check the battery connection, as a bad connection can be the cause. High cable losses can also prevent a full charge, so use cables with a larger cross-section. Ensure that ambient conditions are equal for charger and battery because a large ambient temperature difference between charger and battery can affect charging. Finally, if you have a 24V system, make sure that the charge controller is set to the required system voltage (24V instead of 12V).

If the Victron Energy Controller battery is being overcharged, it could be due to a defect in one of the battery cells; if this is the case, replace the battery. Another possible cause is a large ambient temperature difference between charger and battery. To solve this, make sure that ambient conditions are equal for charger and battery.

Kathryn HolmesAug 31, 2025
If the load output on your Victron Energy Controller doesn't activate, it could be due to several reasons. First, ensure that the output current doesn't exceed the 15A limit. Another potential cause is using a DC load with a capacitive load, such as an inverter; try disconnecting the DC load during the start-up of the capacitive load or disconnect the AC load from the inverter, or connect the inverter as explained in section 3.6. Finally, check for any short-circuits in the load connection.

If the load output on your Victron Energy Controller isn't activating, it might be due to exceeding the maximum current limit. Ensure the output current doesn't exceed 15A. Another reason might be using a DC load in combination with a capacitive load (like an inverter). Disconnect the DC load during the start-up of the capacitive load. Check the load connection for a short-circuit.
