Multiple Inverters / Batteries

[ivanfmartinez]

I'm looking to purchase inverters to my home, and considering Luxpower ans this integration.

I have seen that it can show SoH of battery, how this work with multiple inverters with shared batteries ?

For multiple inverters I have to connect to each one, or the master inverter will give all information ?

Hello @ivanfmartinez
Yes, master will receive all the battery information, if CAN/RS485 is connected to it. This is the best approach
Slaves will receive information from Master.
of course batteries must be connected between each share and master battery should be connected to the master slave.

I have such config and it works just perfect.

Thank you.

Reading the modbus protocol I saw only one SoH, how you get the SoH of each battery ?

The data of each inverter is available or the master send something like summed/aggregated data ?

Can you show your entities for this setup ?

I'm prettending to put 2 split-phase in parallel to get 3-phase and shared batteries.

Hello @ivanfmartinez
One SOH is being provided, it is something calculated inside master BMS.
SOH entity, SOC, and everything related to battery info. There are a lot of entities, so you would need to choose what you need.

thanks
