Solar panel over voltage protection phenomenon and solution
Over-temperature protection phenomenon and solution
Over-current protection phenomenon and solution
This video uses the MPPT series TD2307 controller as an example
Low voltage protection phenomenon and solutions
Over voltage protection phenomenon and solutions
In this video, we introduce the meaning of the TD75V series solar panel charging status indicator in different flashing modes
Battery overvoltage protection
The controller is now in overvoltage protection state
The battery is full and the warning sign flashes
This video uses MPPT series TD2307 to test how fast does the controller track the Max.power point when the sunshine changed
Before testing, we need to prepare a multi-meter and an ammeter to observe accurate data.
Before testing
We need to prepare solar power generation simulation system and electrical parameter tester
For more accurate observation data

Check the LCD screen, the warning icon and temperature icon flash
Press the up key/menu key to come to the temperature display interface
Check that the current controller temperature is 83°,more than 75°
Means that the controller is now over-temperature protected
