After a couple of rounds of discussion here I think I've nailed down all of the specifics of my new system for a remote cabin. I want to thank all those who contributed because I'd not have gotten this far without you! Now it's time to see if I wound up in the right place
This is a DC only system (*no* hardwired inverter) powered by three 265W panels wired in series. They feed into a home made 10AGW Y connector that combines two MC4 and an outdoor Anderson plugs. The Y connector feeds the panel power into 6AGW direct burial wire for 100' until it arrives at a 150v/35A charge controller. The charge controller connects to two AGM batteries wired in series with 8AGW and a 40A breaker between the controller and battery bank. From the batteries is a few feet of 10AGW that connects to a junction box which splits power to two different feeds. The first feed is a dedicated line of 14AGW for a high efficiency 24v DC conversion of an old Servel gas refrigerator protected by its own 5A fuse (max rated draw is 3.2A). The second feed is a 10AGW line to a 12v to 24v stepdown protected by its own 30A fuse. The stepdown feeds a single 10AGW daisy chain circuit designed to power all manner of 12v stuff, from lights to USB charging, from about a half dozen points. When I need 110v I have small and medium sized inverters which I can plug into the 12v circuit.
How does this system look to you all? Have I covered my bases adequately? A previous discussion about VOC reassured me that due to the peculiarities involved I shouldn't have a problem with overcharging the controller.
Thanks!!
