Hi everyone I have a solar system with battery using a Multi RS Solar 48/100
The Multi RS doesn't estimate the battery state of charge correctly so I'd like to connect the RS-485 / CANBUS from the battery to the Multi RS Solar.
the technical details of the battery connection is as follows:
RS485 and CAN interface, which supports communicating with multiple machines in parallel and with the upper computer.
RS485 baud rate is 19200, CAN baud rate is 500K.
8P8C RJ45 Pins Assignment (RS485)
it also has a jumper for "victron compatible" output.
this is the battery from aliexpress... I'm using the 7.7kWh version.
Now how should I go about connecting the battery to the Multi RS?
Do I use a BBB (with an add on CANBUS transciever and VE.CAN to CANBUS cable)
buy a cerboGX and connect multi-rs with VE.CAN cable and BMS with "CANBUS" cable
Can I connect the BMS straight to the Multi RS VE.CAN using a CANBUS to VE.CAN cable of some sort?
any help / advice would be appreciated
