Coleman 18w Solar Charger Kit

I'm considering purchasing the Coleman 18w Solar Charger Kit which includes a 7 amp charge controller. My plan is to permanently mount the panel to the roof of my trailer to keep the batteries charged while not in use. The trailer is kept at a storage lot in Vegas so it will get plenty of sun year round. I'm thinking I just need one panel to "trickle charge" the batteries while we're not using the trailer.

Has anyone used this kit or a similar one before and what were the results? I can get the whole kit for about $85. Any better price options?

Thanks!

I put a 10 watt solar on my batteries to keep them charged but 10 watt didn't do much but I have a dual battery system. For long term storage I'm sure 18 watt would keep 1 battery charged but I'm sure you can get a lot bigger solar kit for $100 bucks. I'd sho p on the net. Try eBay. A bigger solar is always better and the charge controller will keep the battery from overcharging the battery. I just tried the 10 watt cause I had it in my barn already. A 100 watt will give you about 60AH of charge per day with good sun just to give you an idea of charge capacity, I hope that's right. I have 190AHs of battery in my Trailer. So you can see it would take weeks and weeks to charge your battery with an 18 watt solar cell. 30 or 50 watt would be a lot better.

I have two deep cycle batteries, so maybe I will do two panels. Is it as simple as more panels equals faster charging time or is it more complicated than that?

It depends on if you are using a battery disconnect or not. If you use a battery disconnects and you just want to keep the battery topped up from self discharge you will be fine. If you plan an having other thinks running then you will have to do some math to figure out what your current drain is.

Thanks! My wife says I'm hard to shop for at Christmas time, I'll point her in the direction of some solar panels

As far as I know, my trailer doesn't have a battery disconnect.

Just remember that the 18W panels will only give you 12W (1A) of charging max with the simple charge controller they include. That charger will just disconnect the batteries from the solar panel at 14.2V (I think) and back on at 13.6 (I think). I have some of these panels and I am lucky to see 0.75A out of them.

I ordered two panels and the controller. We will see how it works. I should be OK as my intent is just to maintain while not being used at the storage lot.

Panels are installed. The controller is mounted inside a cubby hole above the fridge, which we never use to store anything anyway. I'll let you know how well it keeps the batteries charged.

Good job, they will keep your batteries topped off while not in use. I'm wanting a little more power like two 120watt panels with a more efficient controller to keep mine recharged during 1 days Sun. That way I can drain the 2 batteries during the night with the heater and the next day they can replenish for the next go round. That's an nice setup you have to maintain them. I'm kinda scared about putting screws thru my roof to mount them. I have good sealant so I guess it won't hurt anything.
