Very effective mppt controller!
I use these to power solar Meshtastic LoRA Nodes. I have a 5v6w solar panel and 3 21700(4500mAh) cells in parallel. Output to the Meshtastic node. It has been up on my tower for 3 weeks and it has kept the batteries fully charged even during sub freezing Temps and multiple days of cloudy conditions. Very happy with the DFRobot controller. I have bought 6 of these now and would buy more.👍

Need a larger solar panel
With my 1/2 amp solar panel going through this device, no charge gets to a 5000ma lithium battery at half charge.Guess it takes a bigger solar panel to work. Connecting the solar panel directly to battery charges fine.

Efficient
This board is extremely efficient with a 5 watt panel and a RAK 4631. I charges the battery up to 4.21 volts and manages to keep it peaked on very overcast days. Great combo with a 6,000 mAh battery.
