9.7.3. Interrupted firmware update
This is recoverable and is nothing to worry about. Just try to update the firmware again.
9.8. Operation issues
This chapter describes all remaining troubleshooting suggestions that were not covered in previous chapters.
9.8.1. 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.
9.8.2. Unable to operate as a DC to DC charger
It is not recommended to use the solar charger as a DC/DC charger, for example, to charge a 12 Volt battery from a 24V battery
bank.
Connecting a battery to the PV terminals can, under certain operational conditions, cause damage to the solar charger. This
damage is not covered by warranty.
9.8.3. Relay issues
The alarm relay has 3 contacts, common (C), normally open (NO) and normally close (NC). It is programmed with the
VictronConnect App.
