Have a Question? See What Others Asked

Is it possible to reset this unit? It seems to be stuck on Calcium battery, while mine are LiFePo4, and the battery selection button doesn't work.
Can this handle a 100w solar panel? I’m looking to pair it with a 100w Thunderbolt Solar Panel from Harbor Freight.

Easy to use and set up for various battery options.

I was able to recover the LIFEPO4 batteries out of a damaged solar generator. The batteries and the charging port were all that was salvageable. I made a new solar generator out of a 50 caliber steel ammo box. I have the batteries connected to this charge controller along with solar panels and an inverter. This fits nicely inside the ammo box with the other components.

Keeps ham radio battery charged

Works as described. Keeps my solar panels charging my LiFePO4 batteries for my Yaesu FT-818 at an appropriate voltage and current while operating the transceiver portable. While I haven't tested the USB power ports yet, I am very pleased with this purchase after using it for about half a month.

Solar panel for excavator

Used this to control voltage for my excavator

As advertised, very happy

This unit does everything it was advertised to do. Both of them are working perfectly.

Just OK

It's a mediocre charge controller that has the most impractical terminal hookups.

Would be great except

The opening where you connect the cable is two small. I connected the largest wire I could fit to it about three inches long and then connected a more suitable gauge wire from there. Hopefully that cuts down the resistance.

Advertised correctly, the images are true. Highly Recommended.

Being new to solar, I am building my own portable power station and in need of a small MPPT charge controller (10-20 amp) that will charge 12 or 24 volt batteries. While learning and testing, I have this unit paired with 2 100w folding panels and a 500w inverter. Hooked up my shop fan to it that draws around 90w, while fan is running fine, the charge controller is outputting around 50w to the battery. Everything seems to be running fine and I can run the fan all day as long as the sun is out. Now I just need larger panels to step up the game.

Died in 48 hours.

The thing worked great for about 48 hours. I had it hooked to 2 renogy 100W watt panels in series charging 2 100AH batteries. I got a 500W pure sinewave inverter running a small 3.5CF deep freezer drawing about 60W. I got up 3 hours ago and the things just flashing random lights in full sun. It was cheap enough I'll take the loss and move on to something else. In the meantime my jackery 1000 will be running the system, it can power this fridge for nearly 3 days with no sun so nothing should spoil on me. I think I'll go victron this time.
