Inverter load notes (for reference only)
Resistive load: Ordinary household appliances such as incandescent lamps, induction cookers, fans, computers, microwave ovens, etc.
Inductive load: Motors, compressors, relays, etc. These require 3-7 times larger starting current. Examples: refrigerators, washing machines, air conditioners, water pumps.
Capacitive load: Loads that conform to voltage lag current characteristic. Examples: switching power supplies, energy-saving lamps, electric vehicle chargers.
Key Differences:
Waveform Quality: Sine wave generates pure AC consistent with the grid; modified wave contains more harmonics.
Efficiency: Modified wave is cost-effective but may generate more heat under specific loads.
Adaptability: Sine wave supports all AC applications including precision medical and laboratory equipment.
Equipment Impact: Sine wave provides high-quality power; modified wave may cause interference in sensitive communication devices.
