I'm building out a camper van with a solar powered electrical system.
My electrical knowledge is limited to a collage physics and an embedded systems class, so I would really appreciate it if I could get some feedback on a diagram I put together.
System Overview:
- 1x 100 watt dc solar panel (may expand to 300 watt in future)
- EPEver Tracer MPPT 20a charge controller
- 2x 110 amp AGM/SLA 12v batteries
- DC water pump (without pressure switch)
- Shurflo Switch Faucet
- Various LED lights
- USB charger
- Black and Decker power inverter (might upgrade to sine-wave)
Key notes:
- batteries connected in parallel
- breaker switch to kill input from solar
- master switch to kill output to peripherals
- plan on using a fuse block between all peripherals
Questions
Is there anything blatantly wrong with my configuration?
Does it matter how I connect the positive inputs and outputs to my battery bank?
- Should they just go directly to one of the terminals of the battery?
- If so, which battery (one is much newer than the other)?
- Or can I create a master pole in-between the two batteries?
- Can the Input and output be connected to the same point?
