ECO-WORTHY Solar Charge Controller 30A with Bluetooth,WiFi, APP Remote Connection, Solar Panel Custom Battery Regulator, Dual USB Port Auto 12V/24V PWM for FLD/LiFePO4/SLD/GEL RV Solar System

Solar Charge Controllers come in two varieties, low-cost PWM (Pulse Width Modulation) and the more efficient and much more expensive MPPT (Maximum Power Point Tracker) models. This Echo-Worthy 30A PWM Charge Controller while not as efficient is a great solution for smaller 100W-400W solar deployments using 100-200Ah batteries. A key rating is the maximum amount of current (in Amps) that the controller can send from the solar panels to the battery. Also the voltage of the battery system being charged as well as the voltage that can be accepted from the solar panel/array of panels are critically important. The Echo-Worthy 30A PWM Charge Controller also features a controlled DC Load output which makes it ideal for controlling loads such as lighting without the need for any other equipment such as light relays for dusk-to-dawn control. It also features wide battery support voltages making it very flexible and allowing for growth or system design changes. At its 30A capacity, as an example, one could connect multiple solar panels in parallel to get 24V @ 30A max in any other combination. The LCD panel of the Echo-Worthy 30A PWM Charge Controller allows for at-a-glance review of most of the real-time data, including Battery type, Battery SOC, Voltage and Amperage from the Solar panels and info on the DC Load. This unit can accept up to 75V DC from the solar panels and can charge 12V or 48V Lead-Acid or Lithium battery systems. Its low profile with dimensions of 5.9” W x 3.68” H x 1.29” D and it weighs in at barely 8.5 ounces, while using a nice solid enclosure with pre-drilled holes for easy mounting. Overall it is small and practical for a well-performing PWM controller. One of its great features is the RJ45 removable external Bluetooth and WiFi dongle. This allows for initial setup via Bluetooth, and then with registration in the Echo-Worthy App, the Wi-Fi can be enabled for full remote access and management from anywhere. Not just PWM but even most expensive MPPT controllers just come with Bluetooth but not WiFi, so this is great to see at this excellent price point. By having the dongle external of the controller case, the communication range and reliability are improved, and it also makes it easy to replace the dongle if ever needed, so overall this is a nicely engineered design. While the remote functionality via the App is easy to setup and works quite well, the management app itself is not very polished when compared to other proprietary software, with a very basic interface, no daily data capture just month and year, however the company seems determined to improve it over time and I hope that happens soon. One must ensure to always connect the Battery to the charge controller 1st and program it, BEFORE connecting Solar Panels! This assures that the controller is setup and works as expected and there is no inrush of current or improper output voltage before it is programmed to accept the correct solar input and charge voltages and amperages for the correct battery type. Thankfully the management software make it very easy to choose the battery type and then auto-sets all the charge parameters, but it is also flexible enough to allow for a custom configuration if so desired. For my current test solution I am using a single rigid 100W Solar Panel that outputs about 20V in open circuit and maxes out at about 5-7A in full direct sun. I connected the solar panel through this controller to a 40Ah LiFePo 12V battery that charges during the day and provides power for landscape lighting all night while using about 50W right now, but which I plan to grow. Since my lighting works with either AC or DC from 12v to 24v, the controlled Load output of the Echo-Worthy allowed for a much simplified and easier to control setup, as the controller has a feature to turn the Load ON at night and OFF at daybreak automatically! The battery SOC reported is not very accurate since there is no shunt in place, but that is not critical to this controller and I do plan to grow my solar panels count/input and battery capacity, possibly go to a 24V battery system to use thinner wires and less efficiency loss, as the higher the voltage the more efficient the system and thinner the wiring, so this controller will allow me to do that all the way to 48V batteries without having to replace it anytime soon. Overall I am very happy with this Echo-Worthy 30A MPPT Charge Controller given it was a lot less expensive than other brands for the feature-set and connectivity options, and it is working really well for me, but I will be sure to provide an update to this review should that change…

The ECO-WORTHY Solar Charge Controller has been a solid addition to my DIY solar power bank, offering reliable performance with a few areas for improvement that are mostly for other folk without a BMS. After some testing, I've found that it effectively regulates and protects my custom battery system. The controller’s 30A capacity handles multiple solar panels with ease as I have 4 100 watts, and I’ve consistently seen efficient charging and stable voltage levels. I have not gotten it to 30A via Solar yet though, but everything has been in the green so far. One of the features is the user-friendly interface. The screen's values are very close to accurate. The LCD screen provides clear readings of voltage, current, and battery status, which I can see as very helpful if you don't have a battery management system of some kind. However, the included instructions could be more comprehensive. During setup, I had to rely on online resources to fully understand the correct settings for my battery type, which at least to me, added some unnecessary complexity. In terms of build quality, the controller feels robust, but I did notice that the mounting holes are quite small, requiring precise alignment during installation. I was just making a small DIY power bank with this, so this made the setup a bit fiddly, especially in the tight spaces. On the positive side, the controller comes with essential protections against overcharging, short-circuiting, and reverse polarity, which have worked in my testing. In my tests, I only used LiFePO4 batteries which it does support. In fact, it supports various battery types, but it’s crucial to ensure the settings are correctly configured to avoid potential issues! During my tests, I observed that it maintained a stable charge and effectively prevented overcharging, even under varying sunlight conditions. (From Rain to Heatwave) Overall, this Solar Charge Controller is a dependable choice for managing a small solar power portable system. While the setup could be more straightforward, and the instructions more detailed, its performance and features make it a worthwhile especially for my DIY Power Bank. If you’re prepared to spend a little extra time on installation and configuration, this controller offers excellent value and reliability.

It works but it is very "light", made from plastic, so I question it's durability. Question if it can withstand much stress as others handling this power are larger/heaver. Hasn't caused me any issuse yet but I'm not challenging it. Otherwise it appears to serve its purpose. If it holds up, I'll be impressed.

So far so good, easy install wifi and blue tooth work well

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.

This will not act as an on/off switch unless you have a 12V battery hooked up to it. If you turn it off when you’re done with your appliance (a pump to water the garden in my case) the appliance will turn off, but when the sun goes down the controller dies, and in the morning your appliance will come on. I should have just purchased a switch at the hardware store for my needs. The interface is not easy, and the double tap feature confuses double taps with two single taps. It works, but it could be better

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

This device didn’t work from day 1, trips every 2-5 minutes, then resets, repeats. Factory issue. Don’t buy it. Replaced with different make, happy now.

fait son travail a la percfection quoi de mieux pour le prix

For solar panel with my motorhome. Good sturdy, well built. Had some trouble understanding how to get to a certain area on monitor.
