Just wanted to show my setup. It is a 24VDC setup, (dictated by solar voltage, not possible to go 48V). 30KWh of Battery. Dynamic ESS.

Lynx busbar and fuses is located on the backside. 150mm2 cables for each battery. Only Just managed to fit them in the lynx :slight_smile:

Currently trying to get communication going between the Cerbo and JK B-series BMS´s (B2A8S30P-HC with P-link coms board), I can see the master but not the Slave. Any advice is welcome.

When maxed out my inverter draws “only” 150A from the batteries, which is 3400-3500 W output (all resistive load). I am a bit disappointed about this! as the inverter is rated to 5000 VA. Is this normal? BMS Discharge limit is set to 250 A so no restriction here.

Use common utp cable between the batteries, wire as I did:

Set dipswitch of the slave to one up.

i am using normal utp cables. And the device adr. is set in the bms software (no dipswitches) master set to adr 0 and slave to 1
The master locks the Uart2 to 16! which i find a bit strange

B-series bms and communication is not common i don’t think.
