Morningstar SunSaver 10A PWM Solar Charge Controller (SS-10-12V) - Solar Panel Regulator for 12V Batteries, Four Stage Battery Charging, HazLoc Rated, Low Noise, 5 Year WTY - Designed in The USA

Worked absolutely perfect

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.

This is a quality engineered piece of solar technology. I bought this to work with a 75w panel and a deep cycle battery to power the ARB fridge in my Wagoneer while out camping and exploring. The owners manual is very simple to understand, the product is nicely put together and appears very solid. I've set it up outside and it functions as intended. There is a nice feature of a LVD (low voltage disconnect) baked into the unit if you use the LOAD terminals (10a max on this one). So if you are powering say a water pump off your solar battery, it will turn the pump off at the cut off voltage (11.7v i think) and then reconnect it as the sun hits the panel in the AM. This will help your battery last a lot longer by not allowing the 12v load to draw it completely dead which cuts their useful life waaaay down. The unit will charge either flooded or AGM batteries with a simple jumper for configuration. There is 4 stage charging with equalization used on the flooded batteries every 28 days.Seriously, this piece of hardware is designed to be used in the most remote places by the oil/gas exploration industry on well monitoring equipment so I think it will work for anything a normal person would throw at it. Go buy a 75-100watt panel and a 100ah battery and have yourself a taste of independence from the wall socket. Imagine a small water feature in your backyard that turns on and off with the sun, or a light for that shed without running an extension cord....

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
