30A 12/24V PWM Solar Charge Controller with Bluetooth

This work great!

It has been my experience that Eco-Worthy products are well worth the money. I have been this solar charger for small solar projects for a while now. This unit is very easy to set-up and operate. I have tried a few other manufacturer's equipment and I always come back to this budget friendly unit.

Works as described, prompt shipping, well packaged

Much better than the Renogy 10w controller I originally bought. This seems to be of high quality

I love this brand but I'm not happy with this controller. When I received it I was immediately skeptical and boy did that prove to be true. DISCLAIMER: I never used this product because I have a feeling this is just a re branded version of the 9$ - 25$ "solar charge controller" you see everywhere. This to me looks and feels exactly like that controller but with a higher price tag. I didn't want to take a chance on this because I'm just going to to finally switch to a true MPPT controller. This is not a MPPT controller, I know that. It is a 30A PWM controller and PWM controllers like Amps == Parallel panels vs Panels in Series. A can over panel a PWM controller like this one very quickly with just 3, 100w panels. It will not accept that muc VOC input and will probably fry or throw and error code some controllers just fry. Hopefully this one is protected but I'm not about to throw out 30$. So, your only option for PWM is to turn your panels into add BIGGER array using <= 10 gauge wire at 3x the cost to support the AMPS you need to get to 30A. NOTE: I have many eco-worthy panels 3 from bi facials to battery tenders and they are all awesome. I love this brand and stand behind it which is why I'm so upset about this controller. This just doesn't seem to live up to the other high quaility of the eco-worthy brand. That's my .002$ opinion.

Bought this solar controller as part of an outdoor solar-powered lantern project at my home. I selected this controller vs others because it can automatically turn the lantern lights on at sunset and can be set to turn them off a number of hours later. You can also turn the lights on and off manually from the panel. I'm dinging it one star because as designed the wiring connections are all exposed. I wanted the controller accessible for use and I also wanted a clean look when mounted on a wall, so I modified the controller so the wiring exits out the rear. However if you need to use this controller at anywhere near the vendors' specified maximum current it gets quite hot, so dinging a second star for that. The metal rear panel is all that's used to dissipate heat from the internal components, and those components are only lightly attached to it. I am using it to control just 1 amp of current, so I don't have a heat problem. If I needed to control more current, then I'd modify the controller so its internal components are more firmly attached to larger piece of metal. Despite only 3 stars, this was the most suitable controller for my particular application.

Bueno

I bought this solar charge controller after going through a couple of cheap PWM controllers for the solar panels providing power to the battery in my woodshed (for lights and speakers). The cheap ones worked in the summer, but in the PNW winters, the charge controllers were not producing enough power to get my battery charged back up in the daytime. Plus the last one I tried was very inaccurate. This controller was a dramatic change. Nearly identical readings for the battery voltage compared to my multimeter, and the amps being produced matched what my clamp meter was showing. I was looking for an inexpensive controller that could use my two 100 watt panels to keep the woodshed battery charged, as well as showing the amps being produced and the amps being used. This controller fits the bill at the right price point. This controller is also programmable, as you can set the cutoff point for the load (which I wanted to protect the battery from getting drawn below 50%). Forget the cheap controllers for less than $20. This is the best PWM controller I've found. The next jump would be to an MPPT controller, but those will cost at least $50 more. Some have commented that the terminals are too small for the wires--they are a little small, but they work with the cables that come with the solar panels. I didn't try to wrap the wire around the screw, but just loosened the screw as far as I could without it coming out and poked the wire along one side of the screw and tightened it back down. Worked fine for all 6 wires.

Works as it should and pleased with it so far

Was late arriving and I needed it. Meantime Eco-Worthy , battery supplier, advertised lower price by 40.00. I received return approval only to find I had to pay postage and insurance!! This amounted to nearly 30.00 or almost half or purchase price. This is TOTALLY UNACCEPTABLE. Great product but don't recommend supplier

Says in description it can connect to their app via bluetooth. It does not. Now I have a faulty solar controller and cannot get refunded. Not a happy customer with Amazon or Eco-Worthy.
