I also get High Voltage alerts when ever it is charging only from the smartsolar.
When I charge the battery in combination from the smart solar and the Multiplus I dont get such error.
Any ideas why? and what I need to do since I am afraid that the High Voltage warning is stressing the battery, especially during summer time where there is lots of sun in Greece.
So in summary:
When I charge the battery either from the Multiplus or the Mutliplus + Smart solar I rarely get high Voltage warning.
When I charge the battery exclusively from SmartSolar (which means that the grid is disconnected from Multiplus) I get more than 50 messages of high voltage.
Since the battery is connected to the GX if DVCC is active then the battery is controlling the system.
Is everything programmed with the same voltages for absorption and float?
When offgrid the system will tend to shut down the ac pv before battery full to prevent overshoot as it is easier and faster to controll dc mppts to finish charging so there is an explanation as to why it only happens with the dc solar.
Ideally you would contact Felicity to check if the behaviour is normal. The battery is probably requestin that high charge voltage (check in battery details and parameters)
With newer set ups high cell voltage is not that abnormal.
I had the same problem. I finally solved it by reducing the charging voltage to 56.8. There’s a document by Felicity suggesting it. Check out this thread.
