There is actually quite a bit to learn, explore and test with paralleling these new #jkbms It could have saved me a lot of time, if this stupid PC software would have worked. But it's not, so don't bother using it for #parallel connected BMS.

So, here we go. One of the big advantages and benefits of using these 'inverter' BMS is the #communication to your... well, inverter!
We will workshop how to connect the BMS, set the DIP-switches correctly and let the BMSes communicate with the Victron System.
Well, there are some limitations and unfinished features...

Let's begin!
