2003 Monaco Dynasty which is a 40 footer with a 3kw inverter. This is what I am interested in adding to my existing charging system. We boondocking is limited by our water supply to 3-4 days The lower right is the proposed solar panel, battery and controller addition.
The current system has a 3,000 watt Magnum Energy RV inverter and has a lithium compatible remote control. The current 12 volt wet cells are charged by the rigs 200 watt alternator, 20, 30 and 50 amp shore power and a 7.5 kw generator.
I plan on replacing the wet cells with a single LiFePO4 (maybe second when money is available).
The solar addition will include
1 ea. Vatrar 12V 460AH Low Temp Cutoff LiFePO4 RV Battery
3 ea. Solar panels 435W SunPower : SPR-E20-435-COM for a total of 1,305 watts wired in parallel.
1ea. Victron 150/100A charge controller
I feel comfortable with this component configuration but will listen to alternatives and suggestions. I'm new to this and would rather lean from others than make mistakes.
I do have a concern about the wire gauge of the panel wiring. I plan to connect them in parallel using 3 to 1 connectors on the roof and the rig is prewire with 8 ga for 20 foot.
Thanks in advance.
