10, My Meind Power Inverter will not run my appliance, even though the listed power requirement

10, My Meind Power Inverter will not run my appliance, even though the listed power requirement of the appliance is less than the inverter size.

Electrical appliances can be separated into three load types by the way they draw energy (current) from their power supply. The 3 load types are "Resistive", "Inductive" and "Capacitive". Some appliances may draw all three types of power, in which case all should be considered.

Resistive Loads – A standard incandescent light (wire filament) always draw aconstant power (watts) from the power supply, that is a 100 Watt lightwill draw approximately 100 Watts from the power supply at all times.Larger resistive loads, such as electric stoves or heaters, may require upto 6 times more power. Please make sure you select the correct Meind Inverter to suitthe application you need in order to power the appliance continuously.
Inductive Loads – TV's and stereos (any device with a coil or a transformer in it)require more current to operate than a resistive load of the same powerrating. Induction motors (motors without brushes), as well as sometelevisions, may require 3 to 7 times their power rating to start up. Thiscondition may require repeated “ON/OFF, ON/OFF, ON/OFF” switching of thepower switch on your Meind Inverter in order to get them started. The mostdemanding are those that start under load, i.e. compressors and pumps.Since motor and television characteristics vary widely, onlyexperimentation will determine if a specific load can be started and howlong it can be run. A fridge (electric motor) requires a large surge ofpower (surge current) to start and then typically draws consistent poweronce running. Inductive load appliances contain coils of wire such asmotors, transformers, ballasts and solenoids. When the power is firstturned on these coils of wire draw a large surge current which allows forthe formation of the magnetic field or flux required for these appliancesto work. The magnetic flux is in effect, stored energy. Most commoninductive appliances are: fridges, air compressors, transformers, pumps,power tools & fluorescent lights. These types of appliances can drawbetween 3 and 7 times their normal running power at start up. For example,to start a 200 Watt fridge you may need anything from a 600W to a 2000 Watt Meind inverter.
Capacitive Loads – for example CRT TVs, may require a large surge of current to start,especially if they have not been turned on for a while. This is often dueto large capacitors in the power supply that must be quickly charged whenthe appliance is turned on. If the appliance is not used for several daysthese capacitors slowly lose their charge. Resetting the inverter a coupleof times may overcome this problem and allow you to run these appliances.

Note 1: Some appliances such as large refrigerators, air conditioners or other pump driven appliances, have extremely high demand for start-up current due to an inductive motor which must start under load. Appliances of this type are not recommended for use with an inverter. They should be powered by an engine driven generator.

Note 2: There are no standards for "surge power” partly because it cannot be simply represented by a single sample number. Even though our Meind Inverters can provide up to double the listed continuous power (on initial start-up) for a short period, experimentation is the only method of determining whether it can handle the surges generated by a particular load.
