30A Solar Charger Controller Bluetooth,Solar Panel Battery Intelligent Regulator with Dual USB Ports Auto 12/24V PWM Negative Ground for Lithium,Lead-Acid,Gel Battery

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.

I found it interesting that with the charge controller set to lithium iron phosphate, there is no PWM. Just voltage correction from solar panel voltage to 14.6 volt output. Charge control function is dependant on internal to battery BMS. ( As described in manual if I looked before I bought it) Above you can see the result of this controller and a good MPPT unit. Attached the MPPT unit just a few seconds after eco worthy,so same conditions same panel. MPPT gave 13.92v at 4.1 amps for 59 watts. The eco worthy gave 13.8 volts at 2.4 amps. For 33.1 watts. That is to be expected, nothing wrong with the eco worthy. It is a clean little unit. USB is nice. Load control is configurable and works well intuitive display. Very happy with the purchase.

These work. However, I have found at times they will go bad especially in high temperature weather. (I'm in the desert and it gets hot, very hot, out here). I prefer the 60A model. the only real gripe i have is the wire connection ports are small and can't handle large wires plus the smooth plate screw down doesn't hold as well as other styles.

Very good solar controller. Easy to use. Definitely recommend.

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.

This review is for ECO-WORTHY 30A Solar Charger Controller with dual USB ports. I replaced a HF solar charger with this so I could see at a glance what is going on with my Shed Solar setup. Worked right out of the box perfectly. Just set my battery type using the included instructions and some charging perimeters and away it goes doing its business. I am using a 100 watt panel on the roof and temporarily using a AGM 12/18ah battery. I am using a 600 watt inverter with modified sine wave to run my Worx battery charger. Now for a LiFe battery. Its working good for me. If you look close enough, you'll see my battery is at the lowest shutdown point. I charged two 5ah, three 4ah and four 2ah batteries and it drained it finally. No worries mate... ECO-Worthy to the rescue,.

Just bought this for a spare Never had a problem with the controller. I’ve got when I’m off grid this is probably the weakest link.
