EcoRenovator - View Single Post - 2 Charge controllers on same battery bank!?

Interesting setup idea Ben.

What if you just ran the AGMs on the rack in parallel with your bike's pack? Just plug in and have the batteries balance each other? Possibly too much current?

Anyway, it sounds like the bigger problem is switching from the PV to the UPS and back. Honestly this would be a great place to use an arduino unless you really have a good way of monitoring things and manually switching them. I don't think you'd want them both hooked up at the same time. One or the other will always be backfeeding power into the other because one will have a higher voltage than the other. It would be just like you can't use two chargers on one battery.
