Killed my probably dead batteries, since I either had the two switch setting wrong, of there was a way to switch them off independently. Guessing no, since the previous owner said he just left them both on. I think I might have a dummy proof way of doing it, but feel free to let me know otherwise.
Each starting and charging
system will be isolated. As long as the OFF-1-BOTH-2 switch is NOT in the BOTH position. The switch serves a dual function. In the OFF position it disconnects the house load from the batteries. In the 1 or 2 position, the house load is powered from a single battery
as selected. In the BOTH position, the house load is powered from both batteries, and
the two batteries are connected in parallel. The BOTH position should only be used for special cases, such as attempting to start an engine
and needing additional battery
power. I plan on using this diagram,
See next post
In addition, I am using a Blue Sea ACR between the batteries most likely right at the switch to make sure they both charge regardless of switch setting. To address the issue of being able switch one or both banks completely off I am using a OFF, ON 1, COMBINE switch to disconnect the battery by switching off the ground that has the solar/wind/charging and house loads connected to it, or both. Think it will work without any fires?
