PV and battery voltage check
Use the VictronConnect app, a solar charger display or a GX device to check the battery and PV voltage.
Step 1
If the above step is impossible, use a multimeter in DC mode to measure the battery and PV voltages at the
solar charger terminals.
Step 2
WARNING: Certain solar charger models may have PV voltages up to 250Vdc. Voltages
exceeding 50V are generally considered dangerous. Only a qualified technician should
handle dangerous voltages.
Compare both voltages. Remember that the PV voltage needs to be 5V higher than the battery voltage for

charging to commence.
Possible reasons why the solar voltage might be too low:
• Insufficient solar irradiance is reaching the solar panels:
• It is night.
• There is cloudy or bad weather.
• There is shade from nearby objects. See this
• The panels are dirty.
• There are seasonal differences. The sun angle is lower in winter.
• The panels have an incorrect panel orientation or inclination.
• There are issues with a solar panel or the solar panel wiring:
• There is a mechanical or electrical issue with an individual panel (or multiple panels).
• Wiring problems, like loose wires, loose connections or incorrect crimped MC4 connectors.
• Blown fuses.
• Open or faulty circuit breakers.
• Issues with splitters, combiners or incorrect usage of these components.
• Incorrect PV array design or configuration:
• The PV array is misconfigured. For example, there are an insufficient number of panels in a series string.
• Reverse PV polarity:
• The positive and negative PV wires have been mistakenly swapped when connected to the solar charger. For more
information, see the Reverse battery polarity [45]
