Morningstar SunSaver 15A MPPT Solar Charge Controller SS-MPPT-15L - Solar Panel Regulator, Supports 12/24V LA/Li Batteries. Load/Lighting Ctrl, HazLoc Rated, Low Noise, 5 Yr. WTY - Designed in the USA

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 Morningstar MPPT 15L solar charger is an amazing product, the settings are factory set to actually charge a battery, unlike so many others.The charger is well built, and well designed. Wiring connections are secure.If you get the computer connection module that goes with this, you can change all the charge settings, and the free software from Morningstar gives great graphing and control. One note, if you do change the charger settings, you must power cycle the charger locally for the new settings to take effect. I have had quite a few solar chargers over the years, that would simply pull back too soon to get the battery charged, this one is just amazing. I use this charger with a 250w 40 volt panel, and it all works great. Some other features are a low voltage disconnect if the battery gets so low it is might be damaged, and a lighting control of the load terminals if all you are going to do it night lights. Take a look at the Morningstar products, you will not be wasting your time. If you do get the computer interface, the metered parameters are amazing, way more then I will ever need for sure.

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

My old SunSaver 6L charge controller died after many years of service and I purchased another unit to replace it. The SunSaver 6L is a good unit and clearly well made. The construction is top notch, the screw terminals are easy to use and reliable. There are a couple of status LEDs to provide information on the operation of the controller (input current present, low voltage disconnect operating, charging) which is helpful for a controller used in a remote location. My controller is mounted inside an outdoor enclosure and must be mounted vertically, which is not recommended for optimal cooing. Despite this abuse, the old unit lasted well over ten years before failing.The terminal lugs are plated and well labeled. The unit provides a simple jumper to convert from sealed batteries to flooded cell types.This is a solid, no nonsense controller and I would buy one again. Wait, I did buy one again.
