1. There are 2 LED lights on the MPPT controller, which are red and green. The red light means the battery is dead. The green light means it is fully charged. Real-time monitoring of load charging current, longer battery life.

2. Real-time tracking power is different 

The traditional solar charge and discharge controller is a bit like a manual gearbox. When the engine speed increases, if the gear of the gearbox is not increased accordingly, it will inevitably affect the speed of the vehicle. That is, the traditional solar charge and discharge controller cannot track the maximum power point of the solar energy in real time.

But for the MPPT solar controller, the charging parameters are set before leaving the factory, that is to say, the MPPT controller will track the maximum power point in the solar panel in real time to exert the maximum effect of the solar panel.

3. Different efficiency

Compared with the traditional solar system, the solar system with MPPT controller will increase the efficiency by 30-50%.

Due to the influence of external factors such as light intensity and environment, the output power of the solar cell changes, and the light intensity produces more power. The inverter with MPPT maximum power tracking is to make full use of the solar cells to make it run. at the maximum power point. That is, under the condition of constant solar radiation, the output power after MPPT will be higher than that before MPPT.
