PWM 30A Dual USB Solar Panel Battery Regulator Charge Controller 12/24V LCD (30A PWM solar charge controller)
Description:

Solar panels are a clean and ecological source of electricity.

Obtaining this energy, however, poses a number of challenges for device designers. The amount of energy produced by the panel is strongly dependent on the angle of incidence and the intensity of the light falling on the surface of the cells. This, in turn, leads to unstable power supply parameters at the output, as even shading a small part of the panel may drastically reduce the efficiency.


The optimal solution to the above-mentioned problems is the use of a set consisting of a solar panel, a battery and a charge controller. Such a set allows to ensure constant parameters of power supply to receivers, and also to store energy produced excessively for later use.


The 30A-PWM-LCD solar charge controller allows you to connect panels connected to each other both in series and in parallel - remembering not to exceed the permissible values of current and voltage at the input of the device. Due to the operating characteristics of the PWM controllers, it should be remembered that when the panels are connected in series, the rated voltage at the output for charging the battery is 24V.

PWM stands for Pulse Width Modulation. PWM charge control devices can be explained as an electrical switch between batteries. The switch can be quickly switch on and switch off. Therefore, desired voltage can be obtained to charge the batteries. The charge current will be slowly decreased as the batteries charged.
