Will you be running the inverter at 24 then ? Reason I ask is that even with higher voltages you need to be concerned with wire and connections heating up when running high wattages for long periods.

I run mine at 50 volts, and had to double-up the positives due to heating after about a half-hour. Some of that heat could have been due to too-small bolts on the busbars however.

Yes. The max load should be less than 2,500 watts which would be about 116 amps from the batteries. With 4 batteries, that is only 29 amps from each battery. I won't need to worry about heat build up at all. However, I will be using the Tesla modules built-in temperature control system for warming the batteries on cold days.

how will you be doing that?

the heat is generated by stalling the tesla drive motors, which then pumps that coolant to the battery's?

If I were in that situation I'd at least investigate if I could safely shoehorn a Honda eu3000i or its Harbor Freight clone into the same compartment. It would take a lot of due diligence with respect to exhaust and cooling, but if it was feasible I'd consider it a superior solution.

A water pump and an inline heater.

At 116 amps I think you'll need substantial wiring to the inverter. That's what I'm talking about, not the batteries.

so your just using the coolant tubes is what you meant? i thought there was some 3rd party module that tied into module on the board.

10 gauge wire for 29 amps, 2 gauge if I had 116 amps through one wire, but I don't plan on doing that. They have charts which tell me what wires to use.
