Bangzhao Brand 120V 200A High Power Intelligent Solar Charging Controller

Product Description:

The Bangzhao solar controller adopts a series pulse width modulation (PWM) method, with a wide range PWM adjustment of 0 to 99%, which can quickly and stably charge the battery under any system condition.

PWM charging method uses pulse current that automatically changes the duty cycle to charge the battery. This pulse charging can make the battery more safe and quickly fully charged. During the disconnection period, the waste gas generated by the chemical reaction of the battery has time to recombine and be absorbed, naturally eliminating concentration polarization and ohmic polarization, thereby reducing the internal pressure of the battery and allowing it to absorb more electricity. The pulse charging method allows the battery to have sufficient reaction time, reduces gas evolution, and improves the battery's acceptance rate of charging current.

Solar off grid power generation system

The off grid solar power generation system is mainly composed of main components such as solar panels, photovoltaic lightning protection combiner box, solar charging controller, battery pack, off grid inverter, etc. Using solar panels to convert solar energy into electrical energy under illumination, the DC load is powered by a solar charging controller, while the battery is also charged; In cloudy weather or when there is no light, use the solar charging controller

The battery pack supplies power to the DC load, while the battery directly supplies power to the off grid inverter. Then, the off grid inverter converts the DC power of the battery into AC power, which is used by AC electrical equipment.

The Bangzhao series solar charging controller is an intelligent photovoltaic controller designed specifically for off grid photovoltaic power generation systems. LCD liquid crystal display screen, easy to operate and other good operating performance, and can automatically control the disconnection and connection of solar cells according to changes in battery voltage. This controller enables the full utilization of solar cell resources and maintains battery safety.

In order to meet the needs of different photovoltaic off grid power stations, our company has the research and production capabilities of various specifications of photovoltaic controllers. According to the different voltage levels of the battery pack, controllers with a rated current of 30A~300A can be provided. According to the different voltage levels of the battery pack, they can be divided into series of voltages such as 24V, 48V, 96V, 120V, 192V, 220V, 240V, 360V, 384V, 480V, 492V, and 600V to meet the design needs of different solar power plants.
