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 ...

Yes Isc of a 100w panel should be about 6.3a and you will get that with PWM when panels pointed and sun high enough in blue sky.
Tee hee, snicker, snicker, Full Mosey is starting to sound like me wrt MPPT! :)
Hey man, I always thought I was the one that helped you understand MPPT! :)
Salvo is the one that eventually got through my thick skull on how to properly compare MPPT to PWM.
In short, MPPT excels in low temp, low battery SOC% situations.
Thanks to smk, I now know that the MS MPPT can switch to PWM when it is better. I am taking another look at the MS MPPT 15 for my 170W array. The entry fee for that controller is ~$200.
MPPT could be an advantage this winter in Quartzite.
