An interesting word of caution about the Trik-L-Start device.....

I hadn't thought about that...

Are you going to use this on the RVs that will soon have solar? If so I recommend a Trik-L-Start combiner instead.


For the RVs with solar, I'm going to order this:

5amp seems like plenty for the chassis battery, right? There is a 10amp version that costs twice as much, but that seems like overkill to me.

If this is hooked up to my RV with solar, it seems like it would be able to steal a few amps per hour if needed for the chassis battery and that should be PLENTY to keep it fully charged. Am I missing anything here?

Thanks!
Chris

PS: RV tinkering is addictive.....


Ugh! I can't find the 5amp version anywhere online. Did they discontinue it? Let me know if you know where to find the 5amp version. Otherwise, I'll have to go with the 10amp version that is twice as much.

Thanks!

I have one of these 10W Solar panels always sitting on the dash of my truck plugged into an always hot 12V Receptacle...

My Truck start battery is always ready to use. I am getting up in age now and don't use my truck like I used to do... Truck usually sits in a spot that gets direct sunlight thru the windshield for a few hours each day...

Have not had any boil out of fluids and Battery sees to be always ready for use when I need it to start...

Yes it appears the 5 amp is discontinued. [emoticon]. Could look for some old stock.

For winter storage I would just charge my batteries fully then disconnect the negative cable and recharge in spring. Self discharge in cold weather is very slow compared to summer temps. I do the same thing for my chassis battery and boat batteries also.

I installed a 200watt system from Windy Nation and the controller has an external out put which I have connected a 12vdc programmable timer. I programmed the timer to provide a half hour charge three times a week for topping off the charge to the coach battery. Works good for me.

Install the big solar system and a good quality controller (that will cut out when the battery bank is charged) and call it done. No need for a second system.

If you can't get the big system installed, a 20w should be pretty harmless. They typically don't include a controller because it's not putting out enough juice to boil off the battery fluid. Of course a small charge controller is pretty cheap so if you feel like you want extra insurance, no real harm.
