Our solar

The solar we use now is our third system is as many years. It now consist of three Navajo 250w poly panels that will be mounted flat and ran parallel into a Morningstar TS-MPPT-60. in turn that will be run into a bank of three Lifeline 225 Ah AGM 8-Ds that provide power to the trailer and a Tripp-lite 1250fc inverter.

The panels in series so far have been producing mid 40's for amps but the run up to the mid day is painfully slow after having two tracking systems. Two panels tracking and three flat balance out somewhere in there.

The wiring between the panels, batteries and controller is all 1/0 welding cable. Overkill yes but it was less expensive to buy from a retiring electrician than smaller cable would have been. I picked up a YQK crimping tool to put the lugs on and a roll of marine shrink wrap to make it all look prudy.

It isn't all mounted yet, but it is usable. Each system goes through a ground test and this season is this ones turn. I still have many switches, fuses, gauges and such to buy before I mount it in the fall.

The back up to the system is a Champion 3500/4000 generator and a Megawatt 36a power supply.  We haven't ran it while camping in three years but it is part of a balanced system.

So nothing real complicated. Enough power in peak sun to run many of the appliances we use including a 5000 BTU air conditioner that pulls just 450w's. Enough battery that we don't have to stop living because the clouds rolled in.
