A beautiful little controller that works well and is more than affordable. The two USB ports are my favorite feature. I use one to drive a 24x7 meshtastic transceiver and the other as a phone charger.I paired this with a simple 25 watt solar panel and a 10Ah battery and am really happy with my whole setup.

Great price, perfect for small 300W solar system

We are in sunshine most everyday in the desert and our 200watt portable panel charges our 100ah LiFePo4 battery to make our life easier. Glad I got this before our winter trip. I'd buy this without hesitation.

The unit broke within an hour of use and will not display anything now. Everything was configured perfectly fine according to the instructions, which were very minimal by the way. Within an hour, the unit fried, and there was only one solar panel hooked up to it.

Easy to connect. Should be waterproof as likely location to set up is outside by the solar panel, which is what I did and it fogged up and had water in the display. Still worked.Instructions suck. Quick search found a video on line that was great. Super simple to set and use.I would recommend.

I bought this unit to use in a test environment to figure out basic solar energy electronics.The instructions are confusing but the unit seems to work as advertised.The screw terminals are not of robust quality as after a few tries they stripped and the wires could no longer be secured in the unit. Other MIC Amazon electronics seem to share this quality. I ended up (carefully) removing the terminal block and hard-soldering some wires to board itself via the remnants of the screw-terminal block and put on heat-shrink tubing.I added some quick-connect crimp fittings and it works fine now with the Renology 100W panel.The next step is to actually use it as a power source for some 12V lighting projects.

When I look at the specs, they all appear to be the same dimensions, 30A , 60A or 100A MPPT, so I thought I'd add the weight of the small unit, which was 248g, however the manual said 300.I'm not convinced/ can't comment at this time if it's an MPPT controller or a PWM, however I can say that the connectors worked well. The display isn't super bright, but it does track Ah in and out. In my case, my load is coming off the battery, so it's not tracking that, but still, that was why I went with this controller over the other similar ones at this price point - even if it's not MPPT.According to my measurements, it draws 22 mA when running in the daylight, although the manual calls is 10 mA.You can change your load on/off points so that at 11.5(max) it will shut off the connected load to save your battery and it will turn on again at 12.6 (max). At 12.3V a battery is 50% discharged - not accounting for the "load", so I would ideally set it to 12.0V to shut off my load and not turn it back on until the battery was at 12.9V - showing a reasonable charge based on my 120W panel. I didn't check the minimums, but at least 10.5 for the shutting off as that's the default. As far as max charge it starts at 14.2V, and will only go down as far as 13.7. I'm more afraid of cooking a battery than undercharging it, so I would've went to 13.4 or something. I don't mind putting an actual charger on it occasionally to top it right up - again I'm more concerned with battery health than anything, but I might be alone in that.Lastly, something I didn't realize about it is you can program your load to only come on during daylight hours, or to only stay on 1-15 hours after daylight ends. Or you can manually on/off, but you can't say turn a load on automatically at 7 pm and go to 3 am or anything. Still it could be a useful feature to some. Otherwise if you don't use these settings a quick button press changes you from on and off. The 30A controller allows 10A draw on the load side.

This is straight-forward, no nonsense charge controller. I'm using it with a 50Ah LiFePO4 battery and a ~80W solar panel.It's easy took wire up and works well. The display is easy to read and the included USB ports is a nice touch.If you're not building a permanent setup and the battery will be disconnected often then be aware of the device connection order as shown in the product photos. I'll most likely place a switch in-line to the solar panel.Great value for the price.
