Inverter Load Notes (For Reference Only)
Resistive Load: Works through resistor-like components. Examples: Incandescent lamps, induction cookers, fans, computers, microwave ovens. (e.g., A 2000W induction cooker can be driven by a 2000W inverter).
Inductive Load: Uses electromagnetic induction (motors, compressors). Requires 3-7 times starting current. Examples: Refrigerators, washing machines, air conditioners, water pumps, electric tools.
Capacitive Load: Load with capacitance parameters where voltage lags current. Examples: Switching power supplies, energy-saving lamps, electric vehicle charging power supplies.
Pure Sine Wave vs. Modified Wave Inverters
Waveform Quality: Sine wave generates pure AC consistent with grid power (low harmonics). Modified wave is between square and sine wave (higher harmonics).
Efficiency & Cost: Modified wave is cheaper and highly efficient but generates more heat. Sine wave is more expensive due to complex circuitry.
Application Scope: Sine wave is essential for precision equipment and medical devices. Modified wave is suitable for general lighting and cost-sensitive household use.
Impact on Equipment: Sine wave provides high-quality power for sensitive electronics. Modified wave may cause high-frequency interference in communication and precision tools.
