TD75V series LED indicator meaning under charging status

In this video, we introduce the meaning of the TD75V series solar panel charging status indicator in different flashing modes

Overvoltage protection situation and solutions

Battery overvoltage protection

The controller is now in overvoltage protection state

The battery is full and the warning sign flashes

LDSOLAR MPPT Real-time Tracking Function Test

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.

PWM VS mppt

Before testing

We need to prepare solar power generation simulation system and electrical parameter tester

For more accurate observation data

Over-temperature protection phenomenon and solution

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
