Okay, after a decent amount of research, this is my planned setup on my 16' Bambi:
I'm hoping to boondock indefinitely with light electrical loads or up to 3 days in 20 degree weather (main concern there is the power draw of the furnace).
- 2 AGM batteries 12V
deep-cycle batteries (going to install these underneath the couch by the door - where the sub is - they should just fit there.
- 2 50AMP "switchable" fuses (to switch the system between my 2-battery setup and the one stock battery that's on the hitch tongue). This will allow me to run on / or charge either battery system individually (since they're different types of batteries - they're not supposed to be hooked up together).
- 1 100W Renogy flexible panel (purchased on amazon)
- There's already a 15W panel on the roof from the PO...I plan on using it as well
- MPPT Tracer 2210RN Solar Charge Controller (purchased on amazon)
- I plan on using the factory pre-wire
- 100W and 15W panels wired in parallel. I plan on using 3M 4941 VHB tape and Sikaflex lap sealant to keep out the water. I also might use some 3M 5900 on the corners for extra strength. They're both 12V
panels but I'm not sure about the exact specs of the 15W panel since it was already there...
- Use factory solar pre-wire. I'll drill a hole in the roof and use the West Marine 2-hole wire caps with 3M 5900 sealant.
- Connect to MPPT charge controller.
- Charge controller will be connected to the batters (one on tongue and the set of two inside) through two 50AMP switch/fuses. Only one set of batteries will be connected at a time. The two interior batteries will be in parallel.
What am I missing here? What are the thoughts about the 100W and 15W panels run in parallel?
Also, is there an easy way to add a second 100W panel to this setup - so 200W panels and one 15W panel? Not sure how that can be done...
