Renogy Rover with lifeline AGM batteries.

[azSkier]

My Simple Solar Project is now complicated

For the first time, I am storing my coach outside for the winter in SLC. The coach is going to be very cold in December and January.

I will not have access to any power, so I was thinking I could add 100W solar system to keep the battery in Float during the day. I can place the panel in my windshield and get full sun as the coach is pointing southward.

I been looking at the Renogy panels and the rover 20A controller. I have everything figured out...

Expect how to configure the system to work with my lifeline AGM batteries. The lifeline manual has a charting showing optimal float voltages depending on temperature. These values range from 13.6 to 14.52 at 10 degrees.

The Renogy controller allows me to set only 1 value. It does provide some kind of temperature compensation, but it is not specified.

Has anyone used the Rover with lifeline AGM batteries.

Renogy controllers are pretty limited.

Consider to buy a controller that actually is designed for AGM batteries and temperature compensation.

Unfortunately, charging with the wrong algorithm / temperature compensation will destroy those nice lifelines very fast.

Agree with Harryn, solar is like eating chips, you can't stop with just one. I would buy a higher voltage MPPT controller which will handle any upgrades you might want in the future, without buying another controller. a 150/50 amp or bigger controller will handle 100 watts just as well as 500+ watts, and you will be able to set it up for your particular battery setup.

And if you are going to put up one panel, make it a bigger panel. No need to limit yourself to 100W. Also, Renogy are expensive for what you get.

Get a 180W panel here for less $/watt than a 100W Renogy. US made unlike the Chinese Renogy.
