ACOPOWER 100W Foldable Solar Panel Kit with10A PWM Charge Controller

Very efficient unit. We bought this charger to keep the RV battery charger before 2-week trip through Texas, Colorado, Arizona and New Mexico. It worked like a charm. We were off the grid for 7 days and this solar panel kept our deep cycle marine battery going strong even thought it was often overcast or raining, being the monsoon season in the 4-corners area. We we able to run all the lights we needed and the whole house fan all night, every night, without ever seriously depleting the battery. In the past, we have had to plug in after a day. This unit is a bit large and awkward to transport but it packs up nicely in it's case and is just the ticket it if you want to camp off the grid without sacrificing too much convenience. The instructions were also vague and a bit contradictory, but overall great value.

We have a Roadtrek class B motorhome with a single house battery. Class B's are easy enough to drive and park that we use it as a sight-seeing vehicle, as well as camping in it. All that driving keeps the battery nicely charged. When we do stop for extended periods we can get as much as 3 days out of the batter. Any longer and we need a charge. That led me to looking into solar. Permanent roof top was an option, but was overkill for out application and more money than I'm willing to spend. Space is at a premium in our little motorhome, so I looked at the "suitcase" models. I like that this one has metal legs and a 5M(eter) cord. Our battery is tucked away behind a panel, so I made another connector using ring terminals. I've bolted it directly to the battery. The connector hangs down and is easily accessible.

We used it for the first time last week for 5 days. It did a great job of keeping our house battery fully charged and allowed us to use the roof mounted fan on "high" during very hot weather. It kept the lights burning bright and we were everybody's favorite neighbors for charging phones and Kindles. We had charging voltage when ever we aimed it at the sun, even when the sky was overcast.

All of the hardware is high quality. Corner protectors all the way around, stout aluminum legs, automotive grade connectors, and a very nice carrying case. I bring the battery clamp connector with, just in case we need to charge a chassis batter.

The Acopower 100 Watt folding panel fits our needs perfectly.
