Resistive load: Works through a resistor-like component (e.g., incandescent lamps, induction cookers, fans, computers). A 2000W induction cooker can be driven by a 2000W inverter.
Inductive load: Uses electromagnetic induction (e.g., motors, compressors). These require 3-7 times the starting current. A 150W refrigerator may need over 1000W to start.
Capacitive load: Characteristics where voltage lags current (e.g., switching power supplies, energy-saving lamps).
1. Waveform Quality: Pure sine wave is consistent with grid power, offering low harmonic content and high stability for precision equipment.
2. Efficiency & Cost: Modified wave inverters are cheaper and simpler but may generate more heat and interference.
3. Load Adaptability: Pure sine wave inverters support all AC loads, including sensitive medical and laboratory equipment.
