New to Solar. Conect directly to battery ????

[TenOC]

I am completely new to solar panels. I know almost nothing about them. We boondocks and dry camp about 50% of the time in our 5th wheel. We have 2 deep cycle lead acid batteries. When the batteries need recharging, we have a Champion 3100W Inverter Portable Generator that we plug the power cord from the RV into by the use of a 50 amp to 30 amp adapter.



I want to add a portable solar panel such as Harbor Freight Underbolt Solar100 Watt Solar Panel Briefcase

Can I connect this solar panel directly to my battery with a alligator clips or do I need some type of controller to keep the panel from overcharging my batteries. I think the output of the solar panel is 14 to 22 volts..

I can't get your link to work. Our local Harbor Freight does carry a 100 watt briefcase. It does require a separate charge controller before connecting to batteries.

We have two of the Renogy 200W portable suite case panels. We have had them for several years and get very good results.They allow you to follow the sun for longer daily charging periods with adjustable tilt/angle legs for optimum wattage. They do come with a charge controller mounted on the panels and alligator clip leads to connect direct to battery. They also give you the ability to set up camp under the shade and move your panels out to the sunny areas. This is the main reason we own them. Their disadvantage is set up and take down along with storing them.

My buddy has 2 of these and they work great. Self contained. Directly to the batteries.
