House/solar battery opinions
My current battery space is 20"L x 14"w x 10"H Going solar, and want to packs as much AH in there as I can (reasonably). Currently looking at 250 - 300. Price is not THE deciding factor, unless ...

Hi BFL13,
Magic blue smoke anyone?
MPPT on a 17 volt panel will get you 8%, on higher voltage it will do better than that.
Yes, I believe I can get better than 8% in Quartzite, AZ during Jan-Feb and with low SOC% batteries at morning. That is how MPPT works best.
There is nothing to lo$e if the MS MPPT can choose PWM on the fly if it determines Isc will be more Amps. I do expect more total daily harvest.
I will rewire the 2 x 85W panels into series so that more solar Volts will get to the controller at 24V as opposed to the current 12V parallel configuration.
HTH;
