I have two new Multiplus 24/3000/70 units running in 180 split phase. When connected to shore power on the old lead acid battery bank these units worked without a hiccup. The battery bank has been upgraded to a new LiFePo bank with external VE Can BMS. The charge profiles have peen changed on the Multi's and they have been configured with an assistant for use with a two signal BMS unit for the time being. When coming back onto shore power the Multi's will not transfer and charge. Both L1 and L2 originally showed "out of phase" in VE Configure. I checked shore power, boat wiring and all was as should be right at the inlet of the Multi's. I re-flashed the firmware and the units will connect to the shore power and transfer/charge normally. When I alter the configuration for LiFePo and two signal BMS and send the config the units will no longer transfer and charge and show "out of phase" In the VE monitor. This persists even if I revert the settings back to default. The only way to get the units to work properly again is to re-flash the firmware. This unfortunately leaves me with incorrect charge profiles and no safeties on the system. This problem also persists with the two units isolated on the VE Bus network. Not sure where to go from here. I have reached out to my dealer on this but am awaiting a phone call. Anyone run into this before? I am hoping I am missing something simple but the "out of phase" error it obviously inaccurate as the system connects fine immediately after a firmware flash.
