Pure Sine Wave Inverter With AC Charger

TDS series :pure sine wave hybrid solar inverter with AC charge 

      In the household off-grid system, photovoltaic or wind energy is generally used as a micro-source. When the light and wind are sufficient, in addition to meeting the power demand of the household load, the surplus power is stored in the battery at the same time. In no light or at night, the load is powered by the battery. However, due to the influence of environmental factors on the micro source, the DC side voltage fluctuates; in addition, since most household appliances have inductive motors, there will be shocks at the moment of startup, resulting in line fluctuations, resulting in unqualified power quality output from the inverter , The voltage supplied to household appliances is unstable, which affects household appliances and reduces their service life. 

     Therefore, in order to make household appliances run stably and normally in the household off-grid system, the control technology of the inverter is the key. However, there are few researches on inverters for residential off-grid systems. When the DC side voltage fluctuates within a certain range, the inverter can still output good power quality, thereby reducing the requirements for the input DC bus voltage. Through Matlab software simulation in Simulink environment, the control research of household off-grid inverter is realized.
