Default solar

Been a while since anyone posted to this thread. I'm new here but not to boondocking in an RV. My current system is 250w of solar, 500w wind generator and just purchased 4 - 64w panels so at max I should be able to generate 1KW into 4 12v deep cycle # 29 batteries for a total of 700AH. I use one 1200w (Coleman) inverter for a single circuit 120v (for the TV and HF radio). Everything else is off the 12v system. I have used #2 wire for most of this install so should have minimum line loss. I have also wired the batteries so that incoming current is spread over the entire bank and usage is reversed out over the entire bank - did that make sense? The wind generator is from www.windynation.com and is a PMA 500w one. They have a new system that I wish I had waited for since I think it would have cost less than the home brewed one I put together. PMA generates three-phase AC into a rectifier to 12v so I was able to use #12/3 wire from the gen. to the rectifier (and controller) and #2 to the batteries. I intend to use the 100amp controller for both the PMA generator and the 4 new (used) solar panels since the controller is designed for that. Current 250w solar system is into an MPPT BZ products controller but it is only rated for a max of 250watts. Be interesting to see if this system will stop any use of small gas generator at Imperial Dam. AZ Dec. and Jan.
