What to do if my Victron energy BlueSolar MPPT 75/15 Controller charger does not function?
If the Victron Energy Controller charger isn't working, check the PV connection; a reversed connection can cause this, so connect it correctly. Also, verify that a 20A fuse is properly inserted.
Why is my Victron energy BlueSolar MPPT 75/15 Controller battery not fully charged?
Several factors can prevent your Victron Energy Controller battery from fully charging. Check the battery connection. High cable losses can occur, so use cables with a larger cross-section. A large ambient temperature difference between the charger and battery can be the reason, so ensure equal ambient conditions for both. For 24V systems, confirm the correct system voltage (24V instead of 12V) is selected by disconnecting PV and battery, ensuring the battery voltage is >19V, and then reconnecting properly.
Why is my Victron Energy Controller battery being overcharged?
If your Victron Energy Controller battery is being overcharged, it could be due to a defect in a battery cell; if this is the case, replace the battery. Another cause may be a large ambient temperature difference between the charger and battery; ensure that ambient conditions are equal for both.
Why Victron Energy Controller charger does not function?
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.
What to do if the Victron energy BlueSolar MPPT 75/15 Controller battery is not fully charged?
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).
What to do if the Victron energy BlueSolar MPPT 75/15 Controller battery is being overcharged?
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.
What to do if my Victron Energy Inverter load output does not become active?
If the load output on your Victron Energy Inverter doesn't activate, it could be due to several reasons. First, ensure that the output current doesn't exceed the maximum limit of 15A. Also, if you're using a DC load with a capacitive load (like another inverter), disconnect the DC load during the start-up of the capacitive load. Alternatively, disconnect the AC load from the inverter. Finally, check the load connection for any short circuits.
What to do if Victron energy BlueSolar MPPT 75/15 Controller load output does not become active?
If the load output on your Victron Energy Controller doesn't activate, it might be due to exceeding the maximum current limit; ensure the output current doesn't exceed 15A. It could also be a DC load with a capacitive load (like an inverter) applied; in this case, disconnect the DC load during the inverter's start-up, or disconnect the AC load from the inverter. Check the load connection for a short-circuit.
What causes a blown fuse in Victron Energy Controller?
A blown fuse in the Victron Energy Controller is often caused by a reversed battery connection. To solve this, connect the battery correctly and replace the fuse.
How to fix Victron Energy Controller load output not becoming active?
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.
