I have a newly installed system with a VE Can Shunt and a Cerbo GX. Overnight the system logged two high voltage alarms, one of 14.18v at 2am, and a second of 13.16v and 1pm on a sunny afternoon. I am charging 400ah of lithium, have the charge voltage on the MPPT set at 14.2V. The boat is not plugged in so the AC charger on the Multiplus was not active. A fidge and frezzer were turned on which combined draw about 10amps. Is this a settings issue or something else?
