1500 watt power inverter starting performance

General inductive loads , such as motors, refrigerators, air conditioners , washing machines, high-power water pumps, etc. , at the start , the power may be 5 to 6 times the rated power. 4000w power inverter‍ Therefore, typically inductive load starting , the inverter will withstand large transient power surges . The inverter should ensure reliable starting at rated load , high-performance inverters can be done repeatedly without damaging the starter full load power devices . Small inverters for their own safety , and sometimes requires the use of soft- start or limit start .

( 5 ) harmonic distortion

When independent inverter output waveform is a square wave and modified sine wave , the output current of the inverter , in addition to the fundamental but also have high harmonics , harmonic current will generate additional losses in the eddy and other inductive loads , resulting in part severe fever , 12v pure sine wave inverter‍ is not conducive to the safety of electrical equipment. Square wave inverter harmonic distortion of around 40% , generally apply only to a resistive load ; modified sine wave inverter harmonic distortion is less than 20% , suitable for the majority of the load ; sine wave inverter harmonics distortion is less than 3% , the waveform quality than the quality of the electricity grid fortunately , can be applied to all of the AC electrical loads.

( 6 ) the ability to output voltage stability

It refers to the ability of the regulator output voltage of the inverter . PVS independent solar battery terminal voltage in the charging and discharging process volatile, often lead-acid battery terminal voltage fluctuations of up to about 30% of nominal voltage , the inverter which requires a better performance of the regulator , in a relatively wide DC input range guaranteed to work properly. Capacity due to the use of high-frequency inverter and secondary secondary -width-modulated regulator technology , so the relative frequency inverter has a AC power inverters‍ better stability of the output voltage.
