Nature Power 40158 18-Watt Solar Powered 12-Volt Battery Charger Kit with 8-Amp Charge Controller

We bought this to mount on our rv to keep the battery topped off. The mounting hardware is inadequate and there are no instructions for mounting. If you want to mount it to your RV, you will want to buy additional mounting hardware. The cord is not 11 feet long. It is only 7 feet long -not long enough to run from the roof to the battery bank in most rv's! If you need more length, guess you have to buy more parts if there are cords available or make one yourself. The panel arrived in flimsy packaging that was torn and crushed on two ends. Cost to return it to Amazon is about $29. We purchased it for $105 one day and then Amazon reduced the price by $15. Very disappointed in the product. Wish we had purchased a panel from a different manufacturer. Not happy with product and not very happy with Amazon today.

I puchased of two these kits and one additional panel to maintain my deep cycle batteries on my trailer. One came in a damaged box but was still usable. The 3 in 1 connector to enable hooking multiple panels together is almost impossible to locate from any source, including Nature Power, so I made up my own. The included charge controllers were inconsistant at best. one "kicks in" at 11.6 volts and off at 13.1 v. Another is on at 12.6 off at 13.4.Neither would begin charging at 13v and off at 14.2 as advertised. They don't provide the optimum charge rate for the my batteries but, they help.

The panels are small enough to allow mounting in confined roof areas with the included mounting kits.

I bought 2 units, an 18W panel and a 2Watt panel. One to use with a motorcycle and one to use with a camper. The 18W arrived damaged due to very poor packaging and the 2W had very little output. I am not pleased with these purchases at all

sHIPPING CONTAINER WAS RIPPED BUT NO DAMAGE NOTED. WHEN MOUNTED ON TOP EDGE OF MOTORHOME IT JUST DID REACH THE 4==6V BATTERY COMPARTMENT. PRICE WAS LOWERED FROM 109.99 TO 101.27 LESS THAN 30 DAYS FROM MY PURCHACE. DO I GET REFUNDED DIFFERENCE? DOESN'T SEEM TO KEEP BATTERIES CHARGED EVEN WITH DISCOMMECT SWITCH IN OFF POSITION. SO I DISCONNECTED THE GROUND CABLE (AND NOTICED IT SPARKED EVEN WITH DISCONNECT IN OFF) MUST BE A SLOW DRAIN BUT DON'T KNOW WHAT????
