I am putting together a Solar Charging system on my 32ft Sailboat. It has a 320w Panel, 100/30 mppt controller and 4 225ah 6 v AGM Batteries. I also have Wills Book and it is my goto. I am going to add 1 more Panel and increase the size or add 1 more Mppt Controller. I have a few items I only use while docked such as a Microwave and small Window Unit A/C. While Sailing these item are stowed until next long term Docking. I will be installing a 12v Saltwater Desalination unit and a 12v Windlass at the Bow.
