Most dimmer switches lose their ability to dim the lights when used with an

inverter and operate only in the fully ON or OFF position. Newer dimmer

switches controlled by microprocessors tend to work better in inverter

applications.

Some devices cannot be detected by the inverter's load sensor and will not

operate. Small fluorescent lights are the most common example. This can usually

be solved by plugging in an additional load.

If the battery-bank cannot deliver the necessary amperage to operate a heavy

load, the inverter will shut down. The battery voltage will then slowly rise back

above the low-voltage threshold causing the inverter to resume operation. This

cycling of the inverter will continue until the heavy load is reduced or an

additional source of power is added.

Microwave ovens are sensitive to peak output voltages. The higher the voltage,

the faster they cook. Since the inverter's peak output voltage is dependent upon

battery voltage and load size, the microwave's cook time may need to be

increased.

Most inkjet type printers work well in inverter applications. Laser printers,

however, require a high current for their fusing circuit and are not recommended

for use with an inverter.

When first using a rechargeable device, monitor its temperature for 10 minutes to

ensure it does not become abnormally hot. Excessive heat will indicate that it is

incompatible with the inverter.

If the power consumed by a device is less than the inverter's search mode

circuitry threshold, it will not run. This can usually be solved by plugging in an

additional load such as a 100-watt light bulb.
