Best customer service.
Excellent customer service. The first one didn't work but I was sent a replacement right away and it went perfectly. No problems at all.

Solar Charge Controller Works Great
This 100a version works great and you must do your research before buying any of these items to prevent premature failure and possible fires. I consult for remote solar powered systems on a budget. One thing to note is writing down how many amps you need from this controller as it will output 12V or 24V depending on your setup. I recommend 24VDC battery setups on this, 24VDC inverters, and it will then need solar panels that supply 24V+ to this controller. Its good to read all the instruction booklets for parts to see what its hookup requirements are and its min/max settings needed.

Great Controller
I have a 24 volt solar panel system and it's around 1000 watts. The charge controller work the first time and is keeping my batteries charge from my solar panels.

Great Affordable Controller that protects the system.
Bought this over a month ago and has been working great ever since. I use it so far with one 250w solar panel charging 10 lithium 12v 40ah batteries at 24v. I ran the batteries in pairs of two in series/parallel. I use the off grid system to charge my electric motorcycle. So far I have not been plugged into my home ac power for a whole month. This controller is holding up just fine.

EASY INSTALLATION
I have two JACKERY solar panels and I needed a controller to set them up. I chose this one for it's amperage range and because it was ment to be used with acid batteries. took about an hour to install and began putting out all specified information. So far so good.

Junk
Screen was broken and couldn't get it to work in 12v mode, kept over charging my single deep cycle battery so I put it in my junk drawer. Won't be buying cheap junk again.
