I guess I will disagree. Of course I only have three house batteries and two chassie batteries and live in sunny So. Calif. My little 10W solar will keep my batteries maintained in storage IF they are charged to begin with and the battery disconnect switch in on to eliminate parasitic draws. I also use a TrikLstart.
In the winter time I do have to add an additional 10W portable I toss on the roof.
I love that little solar panel.
I'm facing the same situation when we store in AZ in May for around 6 months (no shortage of sunlight but of course very hot). I have two house batteries and one chassis battery, a TrikLcharger (just installed) and a solar panel which appears not to be working. I think this because the red indicator panel light has never illuminated, and when we returned after storing it for 2 months in Phoenix recently, the house batteries were dead. It transpired though that one of the two house batteries was defective as it boiled the next week.
Questions:-
How can I tell what rating of solar panel I have?
If I determine it's not working by checking output with a meter, can I simply change it for another one by using the existing wiring?
Is it likely it's connected solely to the house batteries?
I'm hopeful that it will be enough to keep all the batteries alive during the 6-month storage.
As a footnote:- What's the consensus on the item at
http://tinyurl.com/76uwkaj please? Having spent some time tonight researching lots of input here on the forum, I can quite see why 100W is tons better than 10W for my purposes. However, I also see that I will probably need a regulator if mine is indeed a 10W. I am on the right track looking at this:
