Well I finely got my project complete installing 8 -60w solar panels on my rig 38CK SOLAR PANEL
I fixed them with none tilting attachments, the cheapest I could find.alum bracketsc/ stanless steel w-lock nuts & antiseze MOUNTING BRACKET
Ran # 10 ga wire from the panels I used stake on butt conectors with dielectric greese & heat shrink through 1” seal tight to 2 combiner boxes from AM Solar,CB COMBINER BOX
4 panels to each box from there I went with #6 wires down through to connect to a FM-60 Outback charge controller.CHARGE CONTROLLER
I ran the + wires & tied them together @ the terminals through a 125a 12v breaker to act as a disconnect then back individual through a 20a 12v resetting breaker to the charge controller, all mounted on the charge controller mounting board I installed in the basement of the trailer.
On the out going side I ran #2/0 welding cable to a 40a 12v resetting breaker through a battery disconnect and then on to the battery banks.
The neg side in I just ran straight to the charge controller and out to the shunt block for the tri metric unit.In #6 wire out #2/0 welding cable TRI METRIC UNIT
The battery banks contest of 4-6v Costco batt. Wired with #2/0 welding cable
And 3 group 27 marine deep cycle batts. 678 Amp Hr total
1 of the 12v batts is wired through an isolator and it just for starting the gen set witch is an older batt the rest are new.
I figure ill run this configuration until I fry the isolated batt then hook the gen up to the regular batts. So they will all discharge & recharge at relativity the same rate
I have a 1800w marine xaniex inverter wired up also using #2/0 welding cable 400a fuse & battery disconnect PRO 1800 WATT INVERTER
The battery banks are fused with 400a blocks & battery disconnects as well. I built my own battery boxes out of hardwood, fiber glassed & resin. I ventilated the top of the box using new vacuum hose kits from Home depot so the have a quick disconnect on the top of the box for when I need to service the batteries. I have also installed a 12v brushless motor from Radio Shack in the exhaust port inside the box so it pushes the air through the vent tube I have the wire for the motor stapled to the box through to the out side and just have male / female connectors there to disconnect the fan motors when you need to service the batteries.
The 12v motor power supply is coming from the charge controller and is set to where it only supplies power when the panels are providing power to the charge controller. The vent tubes are hooked together with a Y connector & vented through the exterior of the basement wall.
The panels are rated @ about 67v 60w and I wired them in parallel. I know I didn’t use the correct fuses on the incoming side …….I have pulled a good load through the inlet side of the 12v 20a breakers and they where holding. I
