   I got the 60A model to run my 40A trolling motor, and charge with a 50w solar panel. Charging worked fine, and it did work with the trolling motor for a couple hours. But it starting giving weird volt readings right before my camping trip, so I panicked and bought one more, plus a new battery. During the trip both charge controllers burned out completely while running the trolling motor. So it claims to be 60A, but can’t even handle 40A. Fortunately I was able to return one of them with no hassle.

   01/10/2021 – I purchased this and a RICH SOLAR 30 Watt 12 Volt Monocrystalline Photovoltaic Solar Panel (https://www.amazon.com/gp/product/B07FN84C9K/) to keep a 12 Volt, 7 Amp-Hour battery charged and to supply power from one of its two USB ports to operate a Wyze V3 camera mounted on a tree outside by a bird feeder; thus making a homebrew solar-powered bird-watching system.My initial system requirements calculations include the following known parameters:The Wyze V3 camera consumes 1.575 Watts of power with night vision IR LED turned off and camera power LED off.MPPT Solar Charge Controller draws 15 mA of current on standby connected to the 12V battery with no external loads.Total power consumed by the camera and controller is 1.755 Watts.Based on these measurements, just over 42 Watt-hours of power would be consumed from the battery every 24 hours. Assuming a new battery is in use, a total of 84 Watt-hours of power would be available so the best-case operation time of the camera with no recharging from the solar panel would be two days.To keep the battery charged would probably require an average of 50 Watt-hours per day from the solar panel due to losses in the battery chemistry when charging and losses in the 50 foot 12 AWG wire (https://www.amazon.com/gp/product/B077Z28343/) from the solar panel and losses in the SUNYIMA 30A MPPT Solar Charge Controller. That would imply the necessity of at least 1.66 hours of sunlight per day on the average. Because my solar panel location can only see the sun for probably 2 hours per day of direct sunlight and maybe another 2 hours per day of partial sunlight due to tree shading I’m hoping the battery will maintain its charge.I did notice the SUNYIMA 30A MPPT Solar Charge Controller voltage display was about two-tenths of a volt higher than what my expensive Fluke meter was measuring at the battery but that’s better than 2% accuracy.I’ll update this review after my system has had some time to operate over varying conditions of solar power output and time in the environment.UPDATE after two days of operation: We’ve had two days of solid rain and no direct sunlight and the battery voltage has dropped to 11.5V which is still sufficient to operate the Wyze V3 camera since it was installed two days ago. Hopefully the sun will shine again tomorrow and get the battery voltage back up to above 13V. The good thing is even when it is raining and no sunshine there is enough light getting thru the overcast rainy skies to raise the battery voltage about 0.2V during the day and power the camera too.UPDATE on third day of operation: Well, two days of solid rain with no sunshine allowed the battery voltage to drop below the default 10.8V cutoff value programmed into the SUNYIMA 30A MPPT Solar Charge Controller and the camera stopped receiving power. Today the sun came up with no cloud cover and around 11:34 AM the voltage on the battery reached the factory default programmed value of 12.6V and restored power to the USB port for the camera. The panel was shaded in the early morning by trees in the east so that’s why it took so long for the voltage to rise from the 10.8V cutoff value to the 12.6V power restore value. I’ve added a screen capture of an Excel spreadsheet that I’m using to record voltage values displayed on the charge controller and weather conditions. So far the charge controller is doing what it is advertised to do!Update 01/16/2021 – Updated Excel spreadsheet image

   Just buy it. It’s a common Chinese tactic to copy hot market trends and sell it for a cheeper price with a feature misleading name. However sometimes they strike gold and outperform the original and this product does just that. This device replaced for me 3 others that each cost more independently and loving the ability to set automatic load on/off times.

   Will update this with a much better quality unit. Wiring connectors are too small. A 12 gage wire is all that will fit. For something that claims to accept 100 amps, it’s not much. No heat sink, the body is plastic and when running 16 amps it got hot. Minimal info on screen except for voltage readings.

   It is a PWM controller, not MPPT. Got about 10 A from two 100 W panels in parallel. However, putting two 100 W panels in series killed the controller, although the maximum input voltage is 50V per its label.It appears the best among several charge controllers within the same price range. It allows a lot of parameters to be adjusted. The adjusted parameters will not be reset after disconnecting it from power. Unfortunately, the floating voltage is the same as the voltage at the absorption stage. It’s a PWM controller and may control the gassing very well by PWM but I don’t have time to test whether it will fry batteries or not.

   I bought this figuring that it was not really an MPPT (the claim about it using amperage was a “clue”, as was that it only operated 12 and 24v) – but a PWM type controller – but if I got lucky, then great.I was setting up a 12v system for experimentation and eventually migrating it onto my RV, or replacing it or other parts as needed. My set up will push a maximum of just under 30A at the controller, so I felt the 60A unit would be a good safety margin choice… remember that the warmer the temperature on the panels, the lower the voltage, but the higher the amperage. Always factor for those max/mins.So far, it has held up well even with an overheated space I am storing it and the batteries in. It does work well, it does report the voltage, amperage and temperatures fairly accurately, and it does work. So as a nice little PWM controller, it’s fine.I held no illusions of it being an MPPT unit, but a lot of people will… so don’t be fooled. It’s OK, but know what you are buying. For the money, it’s a decent little PWM unit, but no, definitely NOT MPPT.

   The first concern is that it states it is a 60 amp charge controller, but the largest wire size you can use is a 10 gauge 30 amp wire. That is for the solar connection, for the battery connection, and the load connection. The load connection is limited to 25 amps. Other than not being able to use wire rated for 60 amps and the load limited to 25 amps, it works good.

   Made my own generation station for my work and yard battery tools. I have all Ryobi tools 40 volt and 18 volt. I have two 100 watt solar panels attached to this controller. That leads to two marine batteries that go to an an A/C inverter. This controller tells you the amount of sun, voltage levels, current direction and all sorts of other things I do not use. I really like the Smile face emoji that tells you everything is working fine. On sunny days I can charge 2 each 18 volt batteries and 1 40 volt battery at a session. Really have not maxed the system but am happy with what it does.

    I purchased a solar panel kit on Amazon which included a cheap controller which would not have likely supported the current draw of my ham radios. This has been a good replacement for that controller.It has more than enough settings, and while using the USB ports to charge my Samsung phone and tablet, both have no trouble charging in fast charge mode. This is a great controller for your ham radio go box.
