Re: AGM Battery Upgrade and Charger
I'm looking for a 25W panel and a controller.
That's roughly 2 amps per hour at maximum efficiency, which no solar nor windgen ever seem to deliver max. Are you sure that is sufficient? It would keep your bank topped, with little to no draw, while you are away. If you were discharged even 25%, at realistic output, it would take days of sunlight to fully charge.

In the harsh marine environment, something is always in need of repair. Margaritas fix everything.
