Hey Jerry...thanks for the run down; that's a bunch of stuff I'm familiar with and coming from an "old hand" (that's a compliment!
) like yourself at off-grid living it makes me feel good that I was travlin' down the right path with regard to my thoughts on solar. I've gots lots of experience with boat electrics with regard to storage systems, chargers, inverters, alternators, and such but not much with solar panels. Your list helps a lot.
I've considered the L-16 batteries (tall buggers); I'll have to make a lower hanging compartment (like some of the stuff on Bruin Gilda) to accommodate their height since the "skirt" that hides the underside of my bus is only 14" in height. I've also looked awfully hard at 8D AGM batteries; I use a lot of AGM's in marine applications and they seem to be doing well...expensive though! But they'll fit under the bus and not require checking electrolyte level, etc...I'm still thinking hard on those L-16's though!
1580 is some serious wattage; who needs an inverter for a microwave!
('course, I've never seen a 12-volt micro! And the power cord would be a little heavy!
). Shoot even getting 50% out of those puppies would keep a bus going pretty well. You've gots *lots* of amp-hours in your batteries; how many days (without sunshine or charging) were you calculating for? And on average (if there is such a thing) what do you think you'll get from the solar panels for total watts/day in Oregon? [You can tell I'm still trying to get a handle on this solar stuff!]
And one last question...since the panels have the ability to put out a lot more than 70 amps how does the rating on the charge controller come about?
