This error will auto-reset after the battery voltage has dropped. This error can be due to other charging equipment connected to the battery or a fault in the charge controller.
This error will auto-reset after charger has cooled down. Check the ambient temperature and check for obstructions near the heatsink.
This error will auto-reset. Disconnect the charge controller from all power-sources, wait 3 minutes, and power up again. If the error persists the charge controller is probably faulty.
This error can only occur when the maximun bulk-time protection is active. This error will not auto-reset. This error is generated when the battery-absorption-voltage is not reached after 10 hours of charging.
This protection is default disabled in all Solar Chargers.
It is default enabled on the Skylla-i and the Skylla IP44.
Our advice is to not enable it on solar chargers.
The charge controller is probably faulty. This error will not auto-reset.
Power terminals overheated, check wiring and fasten bolts if possible. This error will auto-reset.
This error will auto-reset after PV-voltage has dropped to safe limit. This error is an indication that the PV-array configuration with regard to open-circuit voltage is critical for this charger. Check configuration, and if required, re-organise panels.
The current from the solar-panel array has exceeded 75A. This error could be generated due to an internal system fault. Disconnect the charger from all power-sources, wait 3 minutes, and power-up again. If the error persists the controller is probably faulty. This error will auto-reset.
To protect the battery from over-charging the panel input is shut down. To recover from this condition first disconnect the solar panels and disconnect the battery. Wait for 3 minutes reconnect the battery first and next the panels. If the error persists the charge controller is probably faulty.
Communication with one of the paralleled controllers was lost. To clear the warning, switch the controller off and back on
The controller is being paralleled to another controller that has different settings and/or a different charge algorithm.
Make sure all settings are the same and update firmware on all chargers to the latest version
The charger is configured to be controlled by a BMS, but it does not receive any control messages from a BMS.
Check the connection between the charger and the BMS.
Or, when the charger needs to operate in stand-alone mode again:
Note that (solar-)chargers automatically configure themselves to be BMS controlled when they are connected to one.
This error will reset after the CPU has cooled down. If the error persists, check the ambient temperature and check for obstructions near the air inlet and outlet holes of the charger cabinet. Check manual for mounting instructions with regard to cooling. If error persists the controller is probably faulty.
The unit is faulty, contact Victron.
The charger cannot read its configuration, and stopped.
This error will not auto-reset. To get it working again:
