Don't connect the MultiPlus to the BP! This can cause damaging to the BP!
It also would be possible for the Multi to charge the battery trough the BP in reverse direction - what also is forbidden!

Hey,


In order to make everything safe, you should get a true BMS for your tesla system. SIMPbms is what I have found to be the best. They have good documentation and you can connect as many tesla modules as you like.

Read the manual on that page for detailed instructions for where to put contactors and other safe guards.


I am not sure of another way to do it and feel safe. I know the extra $500 is a alot, but it still makes the tesla cells the lowest $/kwh on the market.
