[RE-wrenches] sol ark battery

Wed Oct 9 16:51:58 PDT 2024

I'm watching for responses with interest. Great question.

We usually put a Jbox very close to the battery and use two glands to bring
the cables in. I have a situation right now with a HomeGrid stack that has
temporary cables run to it, and I need to protect the cables over a 10 foot
run to the inverter.

I guess one design improvement would be putting the BMS on the bottom so
you can add batteries easier, but as I mentioned previously, it's not all
that hard.
