12V/24V 40A/50A/60A LCD&LED MPPT Solar Charge Controller

12V/24V 40A/50A/60A LCD&LED MPPT Solar Charge Controller

Model NO.: QWM-1440CAP/ QWM-1450CAP/ QWM-1460CAP


MPPT principle:
The maximum power point is mainly affected by the ambient temperature and the intensity of sunshine. The intensity of sunshine being constant, the maximum output power decreases with the rise of the temperature. The temperature being constant, when the sunshine intensifies, the open circuit voltage of PV battery basically keeps unchanged. But the short circuit current
Increases substantially, thus the maximum output power increases substantially.

This MULTIFIT MPPT solar controller can intelligently regulate the working voltage of solar panels, letting the solar panels always work at Maximum Power Point of V-A curve. Compared with ordinary solar controller, this MPPT controller can increase the efficiency of PV modules by about 30%.

However, due to many different factors, such as the difference in solar panel making, the change the Sun illuminance, change in temperature, the efficiency of the controller etc, the actually available increased rate is 10%-30%

Description of funcitons:

1. The lcd controller is built on microcomputer chip ensures accurate control

2. Perfect protections: Over charge, overdischarge, reverse connection, PV cell panel reverse connection protection

3. The lcd controller adjusts itself automatically to 12V or 24V. It also has 36V, 48V, 72V and 96V DC input voltage.

4. The lcd controller protects the battery from being overcharged by the solar array and from being deep discharged by the Loads. The charging characteristics include several stages which include automatic adaptation to the ambient temperature

5. The mppt lcd controller has a number of safety and LED & LCD display functions for lcd controlelr.
