Selection of Power inverter: 

When selecting a power inverter you should know about the following facts.

Resistive load: Selection of inverter for resistive load (such as heater , toaster , etc..) is simple , the continuous rating of inverter should be considered greater than the maximum power of the load.

For Non Resistive load:  All Television Sets, Monitors, Notebooks, Coolers, Pumps, Machine Tools and many further inductive devices have an extremely high short term starting current. In such cases it is important to consider the following terms and definition for calculation of the required inverter power:

The actual current drawn by the motor depends upon the driven load and on the operating voltage at the motor terminals. If the load increases, the current also increases. If the motor operates at a voltage below its nameplate rating, the operating current will increase. It’s helpful to also understand:

• Motor-starting current. When voltage is first applied to the field winding of an induction motor, only the conductor resistance opposes the flow of current through the motor winding. Because the conductor resistance is so low, the motor will have a very large inrush current (in some cases up to 15 times the rated current).

• Motor-running current. Once the rotor begins turning, there is an increase in counter-electromotive force that increases the impedance and thus reduces the current from the starting amperage to running amperage.

• Motor locked-rotor current. If the rotating part of the motor winding becomes jammed so it can’t rotate, no counter-electromotive force will be produced in the motor winding. This results in a decrease in conductor impedance to the point that it’s effectively a short circuit. What’s the result? The motor operates at locked-rotor current, often six times the full-load ampere rating, depending on the motor Code Letter rating. This will cause the inverter or motor winding to overheat and be destroyed if the current isn’t quickly reduced or removed.

Example:

If your TV equipment indicated an output of 150 Watt, the starting current can be up to 10 times. This would mean that you must select a Power Inverter, which can accept a short term maximum performance of 1500 Watt.
