5.9. Operation issues
This chapter describes all remaining troubleshooting suggestions that were not covered in previous chapters.
5.9.1. Unable to operate as a power supply
We do not recommend to use the solar charger as a power supply, that is without batteries connected.
Operation as a power supply will not damage the solar charger, but it is not guaranteed that the solar charger is able to run all
types of loads. Some type of loads might run, others might not. Especially at low load power, the solar charger is too slow to keep
the voltage constant. As such, we do not provide support in these kind of situations.
5.9.2. Relay issues
The alarm relay has 3 contacts, common (C), normally open (NO) and normally close (NC). It is programmed with the
VictronConnect app.
Use VictronConnect to check the relay functionality setting. When checking the relay check if the relay contacts are opened and
closed when the relay is energized and also when the relay is not energized.
The relay gets damaged if a circuit with a current larger than 8A is connected to the relay contacts. This is not covered by
warranty.
5.10. Errors, and error codes
There are several ways errors are displayed:
• Via VictronConnect, status and history screen
• Via a display
• Via a GX device
• Via VRM (GX device needed)
5.10.1. Error codes
In case of an error, an error code will be displayed via VictronConnect, a display, a GX device or on VRM. Each number
corresponds with a specific error.
For a full list of error codes and their meaning see the appendix:
VictronConnect error reporting
VictronConnect will indicate active errors while VictronConnect is actively connected to the solar charger. The error will show up in
a pop-up window in the status screen together with the error number, name and a short error description.
VictronConnect also displays historical errors. To see these errors, navigate to the "History" tab and look at the bottom of each
day column. If there is an error, an orange dot will indicate an error.
