Due to the presence of about 20% harmonic distortion, it cannot carry inductive loads such as air conditioners, but can carry resistive loads such as lights. The rectifier sine inverter uses a non-isolated coupling circuit, which is simple to install and highly efficient. . How do inductive loads and power factor affect the sizing of your backup system in terms of battery capacity and inverter capability? Your refrigerator may draw 1 amp of current during operation, but only use 60 watts of power. This will. . Inductive loads are motor loads and magnetic (coils, electromagnetic) loads. An old style well pump is an inductive load which will require a great deal of power during start-up, while a newer "soft-start" well. . Almost any solar systems of any scale include an inverter of some type to allow the power to be used on site for AC-powered appliances or on the grid.
