## Questions & Answers

**Q: What's the maximum size panel I can use with this controller?**
A: 100 Watts. You need to add 20% headroom. A 100 (watts solar panel) divided by 12 (battery voltage) equals 8.33 multiplied by 1.20 (20%) equals 10 (solar charge controller amperage)

**Q: Do I need to run my load through the controller, or can it go directly to battery? What are the advantages of running through the controller?**
A: I'm afraid several have misunderstood the question. Without a low-voltage disconnect, the load connections on the controller are provided merely for connection convenience. It should be the same as connecting your load directly to the battery. There is no low-voltage protection either way. Unless you purchase the unit that contains the LVD

**Q: Made in?**
A: Morningstar controllers are manufactured in a fully automated world-class ISO 9001 facility in Taiwan.

**Q: Will this work with my 160w panels on my motorhome**
A: yes it will works, because the solar panel will produce about 10 A/h

## Customer Reviews

### ⭐⭐⭐⭐⭐ Mr. satisfied
*by A***R on May 24, 2025*

Worked absolutely perfect

### ⭐⭐⭐⭐⭐ Excellent! You can't find anything simpler or better for the $
*by M***E on November 11, 2022*

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.

### ⭐⭐⭐⭐⭐ Very nice, quality piece of anyones solar power system. Great for expedition vehicles or home projects.
*by A***N on July 27, 2017*

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....
