Hi,
I'm new to this forum and looking for some info when I rewire my solar on my trailer. I am just now "getting" how solar works. I've not really done anything solar other than accept what was sold to me. I have the following:
1. 2015 CreekSide 20fq. 24' tongue to bumper
2. Came pre wired from factory with a collector box type thing on the roof. #8ga wire from the controller location to the batteries
3. Dealer installed 2-150w Samlex Polychrystaline type panels running the kit supplied 12ga PV wiring to the controller. The dealer bypassed the factory collector box on the roof and slid them under the mounting flange of the factory installed collector and gooped it.
4. All this was collected at the Samlex 30a controller which is about 8' of 8ga. wire away from the batteries
5. All hooked up to 4 each 6v in series then paralleled
6. The system works if all is good and all our ducks are in straight row. But I think there are many efficiencies to be gained by moving an MPPT controller closer to the battery bank, adding one panel and upsizing all the wiring
My plan is the following:
1. Shuffle the panels to allow the installation of a Fantastic Vent over the bed and the addition of 1 each 150w panel to yield a total 450w.
2. Use #10 conductor form the panels to the new weather proof residential type J-box(remove the existing factory installed collector) Run #8 PV conductor from the J-Box to the new controller location
3. Install a new MPPT type controller within 4' of the battery bank.
4 Use #4 wire from the output side of the controller to the Battery Bank
5. I plan to use the existing 8ga wire that was installed as Battery Charge wire as P.V. to the new controller location. It is easily accessed at the new location of the controller and where I'd need to splice it to the new 8ga. wire coming from the J-Box.
6. When I install the new J-Box for the PV wiring collection on the roof, is there any reason I can't just use a standard type of hard plastic/baka-lite type electrical connection block in the J-Box? I think it would simplify the in/out, gathering and consolidation of the P.V. conductors on the way to the controller
7. I've not made up my mind on a controller yet, but I'm bending toward a 60a MPPT type as it would be plenty large............and mot importantly it accepts the size wire I want to use!
Please let me know your thoughts
