I have a MultiPlus II inverter (120, 12V, 3000) with Cerbo GX, Multicontrol, GX Touch 70, along with Victron Orion DC-DC chargers, Victron Solar controllers, etc…
The installation has been working great for a year. Then, a couple of weeks ago, the GX Touch and the VRM app randomly show “off” for the MultiPlus status. At the same time, the MultiControl goes to a 16A limit for shore power, instead of the usual 30A. Then, sometimes minutes, sometimes hours later it goes back to normal. All the while, it has actually been inverting. (My boat is on shore power). When the inverter shows as off, I cannot manually charge batteries to 100%. Similarly, it seems to not automatically charge the batteries when they are low.
I have tried re-programming with the MK3 VE Bus. No change.
Help?
