Modified sine wave inverters should avoid "inductive loads". In layman's terms, high-power electrical products made by applying the principle of electromagnetic induction, such as motors, compressors, relays, fluorescent lamps, etc. Such products require a much larger starting current (about 5-7 times) than the current required to maintain normal operation when starting.

The MPPT solar controller should be more complicated, and the cost is higher. The price is usually several times or even dozens of times of the PWM solar controller. The greatest energy. The MPPT controller can detect the power generation voltage of solar panels in real time and track the maximum voltage current value (VI), so that the system is charged to the battery with a maximum power output.

The electrical structure of the PWM solar controller is relatively simple, mainly consisting of a power main switch, a capacitor, one drive plus a protection circuit, actually equivalent to a switch, connecting the components and batteries together, the voltage of the component is pulled down A voltage close to the battery pack.

The solar controller is mainly used in the solar access mesh power generation system, which can automatically control the multi-channel solar panels to charge the battery, coordinate the solar panel, battery, load operation, monitor the charging state, showing the solar panel to charge the battery.

Ningbo Kosun New Energy Co.,Ltd is located in Ningbo,the main seaport in China and had developed every quickly in this field. With the powerful technology and high quality support,kosun products has exported to many regions and countries.(China DC to AC inverter)

The PWM solar controller refers to the control of the analog circuit in digital output with the microprocessor, which is a method of digitally encoding an analog signal level. Control the analog circuit in a digital manner, it can greatly reduce the cost and power consumption of the system. Many microcontrollers include a PWM controller.
