Very easy to install + flawless performance. there’s no digital read-out, but I don't have time to stare at it anyway. I use a multimeter to check it every now and then and it is ideal every single time

I purchased 4 inexpensive solar charge controllers in the past. None of them lasted beyond five or six months. I decided to spend more hoping for a longer lifespan, and I am very happy I did!

I got the Morningstar SunSaver because I wanted a controller that had a more industrial design and was easy to read at a glance. The other controllers I have seen seemed inadequate or low-quality.

Correction the max input voltage is 32.7v is this controller rated for this? Jeff.
I would not recommend using this controller with your setup.
I am getting 2 300w Canadian Solar panels the voltage on each is max 32v. I will be charging 2 batteries each one with a controller because I have a 12-120 v inverter. Is this charge controller rated for 32v input?
Its rated for Max. solar voltage 30 volts.
