MultiPlus 48/3000/35-50 & Pylontech US2000. Inverter doesn't restart because of low battery...

But the batteries are charged

Configuration: Easysolar 3Kv (Multiplus 48/30000 + MPPT 150/70 + 2 Pylontech US2000plus as an offgrid system) I had it installed with BMS managed by the batteries (CAN.Bus/DVCC...)

One day I switshed the inverter off and after that I noticed that it doesn't start again Showing low battery :-0. Only if I connect the generator it comes back to live...

Just to see were I am I went back to first running setting: BMS automaticly managed by the MulitPlus ...deactivated the DVCC, CAN ect. (MPPT error #67, reseted MPPT) still no change.

In the VRM the low battery is displayed as VE.BUS error.

Any suggestion? THX

Just for the record... if you switch off the Pylontech batteries the inverter wakes up again. So could it actually be a problem of the batteries and their internal BMS?

Hi @Monte Chapparral

MPPT error #67 = BMS not seen, is the battery communicating properly? can you see it in remote console / VRM?

Yes. BMS was visible in VRM and Pylonthech a device in CCGX. Charged 100%.

Error #67 just occured when I went back to the non-via-Can.Bus-Setup (which my dealer me originally recommended btw. I only had to lower the charging settings in the inverter with VictronConfiguer). This was my first running system since I didn't had the Typ B cable to connect the batteries in the beginning...
