I have the first phase of my RV solar up and working.
It's a 12V/120V(via 1000W inverter) Coach and it came with two 6V 220AH AGM house batteries in series. Everything so far is new, so i'm not trying to trash new stuff If I can incorporate it into an expanded system in a practical method.
I have installed four 300 Watt panels and a 150/70 Smart Solar MPPT controller and a 712 Battery Monitor.
Questions I have:
1. Does it make sense to now expand the AGM batteries although in the future I want to go to Lifepo4?
2. If I junk the 12V AGM batteries should I size the new system for 24V?
3. I have yet to install a higher power inverter. This will play into my decision on 12V or 24V. How does this play into with the alternator charging 12V dc to the House Bank?
4. Right now, the solar generates more than the batteries can take, since I'm not using many loads at this time. I will in the near future move the refridgerator to the inverter and other items as well. How does this play into expanding the system to more capacity (battery capacity).
Thank you for your opinions on this in advance.
