Morningstar Corporation SunSaver 10A PWM Solar Charge Controller 12V Batteries, Solar Panel Controller, 12V, White/Black, SS-10-12V

Works well

I own several of these 10 amp models and use them specifically for small applications. I've been running a 165 watt panel on a single deep cycle battery. For lights, 12/24v ice chest and inverter loads- charging phone, flash lights and tools. I can't say enough good about Morningstar and this little Sunsaver. Super simple and reliable. Set it and forget it. It has an excellent built in charging algorithm that you don't need to mess with and it is doing an excellent job of keeping my battery charged. All verified by amp and volt meter. Don't go with those cheap Chinese made $20 ones. They don't work well at all. Tried them. This far surpasses those by a mile. The Sunsaver works great for smaller needs and demands. Don't hesitate to get if this fits your parameters!BTW, I install lots of complicated larger RV and small cabin systems. I love the simplicity of these little units and I don't need to worry about them in the right application.

Excellent product. Hooked up correctly

I have a garden away from the house that is too far to run electricity. I needed an electric fence to keep the critters out and a pump to bring the water in. I have several solar panels a friend gave me so I decided to make my own little solar power set up. I ordered one of those cheap Chinese made charge controllers to save a few bucks. Well, that was a mistake. The thing was DOA and looked like a piece of junk. The instructions were in Chinglish.I decided I needed a better controller so I did a little research and came upon the SunSaver on a sailing website. I figured if it could stand up to the salt water, it could take the weather and would be reliable. Since it was cheaper to order through Amazon, I ordered it here. It's hooked to three 40 watt panels that put out 7.5 amps. I have a deep cycle battery that it charges. There's a 12 volt fence charger hooked to the battery and a 12 volt water pump that I hook to the battery when I need to water. I installed it a month ago and it is working just fine.I would urge anyone who is looking for a solar charger to pay the extra few bucks and get a well built, quality product like the SunSaver. It's worth it.Update: It's Spring now and my controller is still working. It was hooked up all Winter with temps down to -37F and has worked flawlessly. It is mounted under the solar panels open to the air. It appears no worse for the wear.Update: It's been through another brutal Winter outside and is still working!Update: 3 years and counting, still works like a charm

Had to replace an older SunSaver 6 12V, so we bought this SunSaver 10 12V for our RV's 85 Watt solar panel system. Like the new three battery lights showing status of the system. Old SunSaver 6 just had the single green "charging" light only.Charge controller is built well, and easy to install. Instructions are written well.UPDATE: Returned from a two week trip in our RV (to get to eclipse totality zone!). Unit is working fine, and keeps us updated on system charging status. Appreciate the 3 colored status lights! Good update by Morning Star.
