Test Method PWM vs MPPT ?
I might get a chance to compare MPPT with my PWM on the set of two 100w panels. I get 12.6 (Isc) now with PWM so that is the "standard" I was thinking of a quick connect set-up to swap controllers...

If Battery Acceptance becomes a factor for the higher voltage test in the 14s, I have a drill for that. I turn off solar, turn on some lights to lower the voltage, note the neg amps on the Trimetric, turn on solar, note the new amps showing and the diff is solar. As long as solar amount is the most solar can do, we're good or else I turn on more lights.
You do have to be quick though, since lights dim and then draw fewer amps. OTOH, an inverter has amps creep where it draws more amps as time goes by and batt v falls.
With the 458AH bank it will still take 20amps when batt v gets to 14.3 or so anyway, but not for long after, that is true. And we are talking somewhere over 12a here.
Sun panels are made by Chinayard. Have curves for 24v but not 12v. Expect are the same as most others though.
I don't have the model number if there is one, I am not at the trailer site till later in the week.

the local dealer is out of stock waiting for a new shipment so he is taking a break if anyone is wondering where he got to. :)
