1.NK Series Working Principle
Solar home inverter working principle: when the normal work of the solar photovoltaic controller by inverter power supply, then the input dc inverter is transformed into the pure sinusoidal alternating current output. When abnormal PV input, battery to the inverter power supply. When the battery discharge into the low voltage point, system a battery low voltage signals, and then into the grid operation mode; When solar or battery voltage, dc voltage return to set up the system signal dc output is normal, and then into the inverter running mode.( Inside the machine has two 50A built-in solar controller)
2.Optional Solar & Wind Solar Inverter
Solar wind power All-in-one inverter working principle: when the solar & wind energy is normally working. It power the inverter through the photovoltaic controller and wind power controller, And charge the battery at the same time. Then the inverter converts the DC input to the pure sine wave AC output. When the photovoltaic & wind energy input is abnormal, battery supply the power to the inverter. When the battery pack is being discharged into the low voltage point, the system sends the signal of battery low voltage, then converted to the mains operation mode; when the wind solar power or the battery voltage is restored to the DC voltage point in setting, the system sends a normal DC output signal, then Switch to the operating mode of the inverter.
