8.1. Solar charger is damaged

Before proceeding with troubleshooting, it is important to inspect the solar charger for any visible damage. Please note that
damage to the solar charger is typically not covered by warranty.
By conducting this initial visual inspection, you can identify any visible damage that may impact the functionality of the solar
charger:
Visual inspection
Examine the solar charger for any signs of mechanical damage to the housing or electrical terminals. Please be
Step 1
aware that this type of damage is not covered by warranty.
Inspect the electrical terminals of the solar charger for signs of burning or melting. This type of damage is often
caused by loose electrical connections, the use of rigid core cables, or exceeding the MC4 terminal current
Step 2
ratings. Please be aware that this damage is not covered by warranty. Refer to chapter
or melted [54] for more information.
Look for any indications of water damage or corrosion on the solar charger, especially around the electrical
Step 3
connection area. It is important to note that such damage is not covered by warranty.

8.2. Solar charger is unresponsive

If the solar charger is unresponsive, it means that none of its LEDs will illuminate or blink, there is no charging activity, and it is
unable to establish communication with the VictronConnect app through Bluetooth or the VE.Direct port.
Conversely, if the solar charger is active, you will notice its LEDs are either illuminated or blinking, and it can successfully
communicate with the VictronConnect app via Bluetooth or the VE.Direct port.
The solar charger should activate as soon it receives power from the battery, the PV supply, or both. Note that the solar charger
does not have an on/off switch.
To troubleshoot, verify that the solar charger is receiving either battery or PV power, using the below procedure.
Unresponsive solar charger troubleshooting procedure
Step 1 Set a multimeter to DC voltage mode.
• Measure the voltage between the positive and negative battery terminals of the solar charger.
• Measure the voltage between the positive and negative PV terminals of the solar charger.
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.
