Asked by: ws309
Yes, that is exactly why we bought it. We are starting with ONE 160 watt panel but wanted this controller in case someday we want to buy a 2nd 160 watt panel.

Will this controller handle 3 GS Star 100W panels

It is a 360 Watt controller, so we figure it handles any combination of panels up to 360 watts.

Customer Reviews

320-Watt MPPT Solar Charge Controller is rated 4.3 out of 5 by 3.
Rated 3 out of 5 by from Product OK ; Home Depot Advertizing Incomplete. Home Depot's advertisement says this is a 320 watt MPPT controller. It may be, but I have a 24vdc system on my camper with two 12vdc deep discharge batteries in series. No where does Home Depot tell you that this is only meant for 12vdc battery banks. I had to return it because I didn't want to produce $183 dollars of smoke.

Rated 5 out of 5 by from We love it, it does the work it's supposed to do! We purchased this with the Grape 160 solar panel and found installation was a breeze. My boyfriend who I convinced to purchase this loves how it shows him the battery levels among all the other features it does. We knew it was a little "overkill" as it's twice what we would need for our solar panel but figured this way if we purchase another panel down the road, we already have a controller that can handle it with ease. It's nice to know it's there helping our panel do the best job it can and protects our batteries from over charging.

Rated 5 out of 5 by from Works very well very fair price. Support was superb. Works very well very fair price. Support was superb. If you dont need 500 watts then this 320w unit has all the bells and whistles you could want and the eppt maximizes your solar rays. Good stuff.
