What is an MPPT Charge Controller?

An MPPT, or maximum power point tracker is a DC-to-DC converter that optimizes the power between the solar panel array, and the battery bank. Basically, they convert a higher voltage DC output from solar panels down to the lower and consistent voltage needed to charge batteries.

So far so good.

Light weight, easy to install. Shuts itself off when the sun goes down. Nice display. Great price.

Solid Charge Controller

I am impressed with the build quality and performance of this unit. If I was to try and improve the function I would add a second PV input for more flexibility.

Nice 48v Battery Charger

I have this solar charger to charge 4 200AH AGM batteries. These batteries can be used so I can have some off grid power for my house incase we lose grid power for an extended period of time. I don't want to have to rely on a gasoline generator. for power to my house. What happens if we can't get gasoline? I have 14 solar panels going to a Min5000TL-X Growatt grid tie inverter (bought from Signature Solar). In addition to this, I have 14 panels going to this 48v Solar Battery Charger... So I am good to go now...
