I think your battery bank is AWESOME!
What gauge of wire will you install on your pos and neg posts and what are the maximum amp hours you expect to draw from your bank?
Thanks and you are welcome. Hope the O-scope pictures showed you what you wanted to see.
I have a 150A BMS which is capable for 150A continuous. I did not go larger mainly because the form factor changes and I would not have been able to fit it into the group 27 case as well, also, that is ~1,950 watts and I have nothing that will need that much power. Fridge runs 24 hours/day and draws 60W, and the microwave is only 1,000W. Other than that... I'd manage loads.
So I will get a gage wire to handle 150A continuous.. probably a 1/0 gage. I need to change out the main positive lead in the battery to match the BMS P- lead in any case. It was all I had at the moment and it is a gage smaller.
As far as how many amp hours I will draw, it will depend on the solar situation and the circumstances related to running the generator. In the absence of solar keeping up... I will probably take them down to between 30% and 50% and that will just be so the Generator can run for shorter periods.
