Why is my Victron energy SmartSolar MPPT 150/45-Tr Controller not fully charging the battery?

If the battery is not fully charged, check the battery connection. High cable losses can also prevent full charging, so use cables with a larger cross-section. Ensure that the ambient conditions are the same for both the charger and the battery. If you have a 24V or 48V system, the charge controller might be set to the wrong system voltage (e.g., 12V instead of 24V); manually set the controller to the required system voltage.
