Review: 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.👍
Review: Good buy, quality item. - Worked well for what I needed. I used this for a solar project for my son. It has all the connections that you would need and is very well made. Good price for a good item.

## Questions & Answers

**Q: if no power is going through the solar panel, can this be set to automatically turn on?  In other words does the 5v auto turn on when it gets dark?**
A: It automatically turns on when power is supplied from the panel. In the interim it draws from the battery.

**Q: How do i mount the cooling fin? is that what the 3m tape is for? and i it suppose to have direct contact?**
A: That is a good question. I didn't put on my unit and it is working fine.

**Q: what is the minimum voltage from solar panel needed? my location is partialy shaded so I get 5.5 in direct sunlight in morning and 3.5 in afternoon**
A: The minimum voltage required from the solar panel is 4.4-6V. In your case, you could connect a 3.7V Lipo battery at the BAT IN side. When the sunlight is not strong, the device can be powered by the lithium battery. When the sunlight is intense, the solar panel can power the device and also charge the lithium battery.

**Q: Open circuit voltage is 7.2V operating is 6 volts on my solar panels will this work with solar power manager 5 volt 6 volts max**
A: I had a little trouble with one of mine that had open circuit voltage above 6v. I opted for installing a step down circuit to drop it to 5v and it works like a champ.

### ⭐⭐⭐⭐⭐ Very effective mppt controller!
*by S***S on February 8, 2025*

### ⭐⭐⭐⭐⭐ Good buy, quality item.

Worked well for what I needed. I used this for a solar project for my son. It has all the connections that you would need and is very well made. Good price for a good item.

### ⭐⭐⭐⭐ Good, but doesn't restart if battery dies
*by P***L on March 23, 2021*

Good product, works as advertised. Fully charges the battery from solar, and the reverse indicators are nice to have, just in case. Only con is that if the battery fully dies, the circuit won't restart outputting power to the load. It will recharge the battery, but I have to disconnect and reconnect the load in order to get power to flow again, which is obviously not ideal for applications where the circuit is less accessible. Paired with a large enough battery though, this shouldn't be a concern.
