[Rhodes22-list] Solar panels?

[jpd9668]

Only had 2 at a time. He had to replace 2 on two occasions. The two that came with the boat had been removed and stored indoors for five years. I winter stored  them each year on a 3 stage charger with float and an equalizer. They were 12 years old when I replaced the them.JoeSent via the Samsung Galaxy S22 5G, an AT&T 5G smartphone

Why did they have 4 batteries? Might be a herring... But my boat had 2 withthe factory setup from 2011 and the small panels wired as peter described.If it wasn't for indoor storage I wouldn't have turned the batteries off.In the slip I could leave the lights on and not have to connect to shorepower or worry.On Sun, Nov 5, 2023, 4:35 PM jpd9668 <jpd9668 at gmail.com> wrote:> Peter,The previous owner of Respite had to replace 4 Group 29 batteries.> He said it was the solar chargers.
