MPPT solar charger manual
Check the connection between the charger and the BMS.
How to reconfigure the charger to standalone mode:
The charger automatically configures themselves to be BMS-controlled when they are connected to one; either direct or via a GX
Device. And that setting is semi-permanent: power cycling the charger will not reset it.
Here is what needs to be done to make the charger operate in stand-alone mode again, ie. not controlled by a BMS:
• VE.Can solar chargers, go into the setup menu, and change setting 'BMS' from 'Y' to 'N' (setup item 31).
• VE.Direct solar chargers, reset the charger to factory defaults with VictronConnect, and then reconfigure it.
Error 68 - Network misconfigured
Applies to SmartSolar/BlueSolar chargers VE.Can (FW version v1.04 or higher) and SmartSolar VE.Direct chargers (FW version
v1.47).
To clear the error on the SmartSolar VE.Direct chargers update the FW version to v1.48 or higher.
To clear the error on the SmartSolar/BlueSolar chargers VE.Can, update the software. If the error persists, it will be because the
charger is connected with both a VE.Direct cable and on VE.Can. That is not supported. Remove one of the two cables. The error
will disappear and the charger will resume normal operation, within a minute.
Background:
Error 68 indicates that the charger detects multiple conflicting network sources, with the same priority, trying to send the same
information to the charger. VE.Can and VE.Direct interfaces have both the same priority level, and BLE (using VE.Smart
Networking) has a lower priority.
Having a higher priority level means that, if the same information (e.g. Battery voltage sense) is being received from both VE.Can
and BLE (using VE.Smart Network) by the charger, the information on VE.Can will be used and the one coming from BLE will be
ignored.
Now, if the same information is being received from two interfaces that have the same priority level (as VE.Can and VE.Direct),
the charger does not know how to prioritize those, causing error 68 to be triggered.
Error 114 - CPU temperature too high
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.
Error 116 - Calibration data lost
If the unit does not work and error 116 pops up as the active error, the unit is faulty. Contact your dealer for a replacement.
If the error is only present in the history data and the unit operates normally this error can be ignored safely. Explanation: when
the units power up for the very first time in the factory, it does not have calibration data and an error 116 is logged. Obviously this
should have been cleared, but in the beginning units left the factory with this message still in the history data.
SmartSolar models (not the BlueSolar models): upgrading to v1.4x firmware is a one-way trip, you cannot go back to an older
firmware version once you upgrade to v1.4x. Reverting to older firmware gives error 116 (calibration data lost), this can be fixed
by re-installing the v1.4x firmware.
Error 119 - Settings data lost
The charger cannot read its configuration, and stopped.
This error will not auto-reset. To get it working again:
1. First, restore it to factory defaults. Click on the three dots located in the top right in VictronConnect.
2. Disconnect the charge controller from all power-sources.
3. Wait 3 minutes, and power up again.
4. Reconfigure the charger.
Please do report this to your Victron dealer and ask him to escalate it to Victron; as this error should never happen. Preferably
include firmware version and any other specifics (VRM URL, VictronConnect screenshots or similar).
