I use that same panel hanging off of the stern rail, connected to a Victron 75/15 MPPT controller with the Bluetooth dongle, and a Blue Sea System ACR to keep two group 24 AGM batteries topped up all summer.
It has worked great for the last three seasons. I've never had any issues (except for my first season, when I didn't take the batteries home until December and had to replace one of them). As a bonus I get to pretend I understand all the graphs displayed in the Victron app, and all the data I log from the controller: https://docs.google.com/spreadsheets/d/1j-H-lw-B89Er6JUJsCqsGhIkCOiLz1Z_6XzcCX4kv2w/edit?usp=sharing Links to parts mentioned above: https://www.amazon.com/Victron-BlueSolar-Controller-VE-Direct-Bluetooth/dp/B07235YXT2/ref=sr_1_10?keywords=victron+mppt&qid=1579280973&sr=8-10 https://www.amazon.com/Blue-Sea-Systems-Automatc-Charging/dp/B000OTIPDQ/ref=sr_1_1?dchild=1&keywords=blue+sea+acr&qid=1579280953&sr=8-1 https://www.amazon.com/Sea-Dog-327199-1-Removable-Clamps/dp/B00TUNSR9Y/ref=sr_1_1?keywords=seadog+rail+mount&qid=1579282098&sr=8-1 On Fri, Jan 17, 2020 at 12:00 PM <cnc-list-requ...@cnc-list.com> wrote: ---------- Forwarded message ---------- > From: Joe Della Barba <j...@dellabarba.com> > To: cnc-list@cnc-list.com > Cc: > Bcc: > Date: Fri, 17 Jan 2020 09:50:08 -0500 > Subject: Re: Stus-List battery charger > When I am on my mooring I have a 50 watt solar panel I put out.
