I am having issues with my Multiplus-II 12 3000 120-50 2x120v randomly rebooting.
The system 50amp shore power, Onan marquis gold 5500 generator, no solar, 4 - 100 ah lithium batteries.
The typically scenario for the random reboot, regardless of power source, 50amp, 30amp or generator. After the batteries have reached something less than 100 SOC and the source power is turned on the Multiplus-II starts the standard bulk charge it may or may not reboot when switching to absorption phase.
As an example: yesterday, batteries were at 92% SOC after a day of travel. I plugged in to 50amp and bulk charging was taking place. At some point before 100% SOC the unit rebooted several times than went to absorption. Another reboot happened during the absorption, once float was hit no more reboots. In yesterdays case there was no load other than the charger.
First is this normal? If not, how do I start to diagnose this issue?
