I've got two Tesla Model S modules (~237Ah each, still testing) powered by 1040 watts of solar. My batts run my 24v 2400w inverter to power some critical loads in my house 24/7. My inverter draws between 7-20 amps during a day, about 10-50% of it's rating, spiking to 60 amps for fridges starting. I want to dabble in rolling my own batteries and need some help.
If I build a 100Ah battery (or a couple of 12v 40Ah) and parallel it with my two Teslas, I'm effectively limiting their capacity to 100Ah (40Ah) each, right?
If left connected my inverter will kill my 100Ah pack while still drawing happily (and unaware) from my Tesla batteries, right?
Ultimately I want to build a 24v xxxAh battery to compliment my two Tesla batteries. I want to start small and take my time. I think that I would like to build 4-6 12v packs that occupy the space next to my batteries (not up above, that's for later...). I want build 12v packs because I envision being able to pull one or two offline in an emergency and use them for whatever.
Here's a pic of what I have. I would appreciate your suggestions for getting some packs built, getting them incorporated or ready to use and any other considerations I missed. Thanks!
