Problem Loads
The inverter can drive most loads, however, there are special conditions that can cause a load
to behave differently than expected. The following describes some of the common problems
encountered when using an inverter.
Ceiling Fans
Most large diameter, slow turning fans run correctly, but generate more noise than when
connected to utility power. High speed fans tend to operate normally.
Cell Phones
Some cellular telephones experience interference in the form of a clicking sound.
Computers and Sensitive Electronics
Some computers and sophisticated electronics have power supplies that do not present a
load until correct line voltage is available. When this occurs, each unit waits for the other to begin.
This can usually be solved by plugging in an additional load (such as a lamp) to bring the inverter
out of its search mode. Also, when using a computer, avoid starting large loads.
Consumer Electronics
AM radios tend to pick up inverter noise, especially on the lower half of their band.
Inexpensive tape recorders are likely to experience noise as well. When using sensitive
electronic devices, avoid starting large loads.
Clocks
The inverter’s crystal controlled oscillator keeps the frequency accurate to within a few
seconds a day; however, external loads in the system may alter the inverter’s output waveform
causing clocks to run at different speeds. There may be periods where clocks keep time and then
mysteriously do not. This is because most clocks do not draw enough power to trigger the load
sensing circuit. In order to operate, especially with no other loads present, the inverter’s load
sensing circuit will have to be defeated. Refer to the Operation/Search Mode Watts.
Decreasing Loads
If the amount of power a load draws decreases after it has been switched on (such as with a
small motor) and its current draw becomes less than the load sensing threshold, it will be turned
alternately ON and OFF by the inverter. This can usually be solved by plugging in an additional
load (such as a lamp).
Dimmer Switches
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, microprocessor controlled dimmers tend to
work better in inverter applications.
