Hi We have a tiny home site, running an easy solar 24 3000 and 2 x 12 volt 200Ah victron (non smart) lithium's in series with the comms cables dasiy chained together, running a separate VE bus bms connected to the multiplus via an rj45 cable
The system wont balance the 2 batteries, 1 battery is at 12 volts the other 16 with high voltage alarm. Any clues please
The Multiplus is runnning 413 and in an attempt to upgrade to 459 via VE flash he can no longer get communications with the Multi plus, he is using an MK2 adaptor on site
