Building a small system to run a small water pump and possibly other small loads in the future. Pump has a 10w draw at 18v.
Looking at a Victron MPPT 75/10 12/24v SCC, with 2 100w panels, and battery hookups new Lifepo4 battery. Looks like it would be easy to series it later if I decide I want more power. Plan is to run it as 12v for now and use the drok converter to get 18v. It doesnt appear that the battery has a low temp cutoff so I might have to add a Victron smart battery sense later on to keep it from freezing as the battery will be outside year around. I also will need to find a water tight box to fit everything in, not sure if it will overheat during the summer though.
Any thoughts or critiques are welcomed. Thanks for looking.
