To display the output wattage demand from all equipment connected to the power inverter, set the display switch
to WATTS. The output wattage draw information provided in this display mode is very useful in determining if an
additional piece of equipment can be powered by the inverter without exceeding the rated output of the inverter.
Assessing the Capacity of Your Power Inverter to Power a Specific Device
When you first switch on a powered tool or appliance that utilizes a motor, that device requires an initial surge of
power. This initial surge of power required to start the device is referred to as the "peak power". After initial start-up,
the device then requires less power to operate, which is referred to as its "continuous power".
It is important that you determine both the "peak power" and "continuous power" demands of any device you plan
to operate using your power inverter. The power demands of any particular device are usually stamped or printed
on the device and are usually expressed in either Wattage (Watts) or Amperes (Amps). If this information is not
indicated or the device, reference that device's owner's manual or contact the manufacturer to ensure that it is
compatible with a modified sine wave power source.
To determine the power needs of a particular device, use the following formulas:
Amps Indicated x 115 (AC Voltage) = Watts
(This Wattage amount is roughly equivalent to the "continuous power" demand
Watts x 2 = "Peak Power"
(This is roughly equivalent to the initial "peak power" demand of the device at start-up)
In most cases, the "peak power" demand of the device is the determining factor in whether your power inverter has
the capacity to power that device. To determine whether your inverter has the capacity to power a specific device,
test that device using your power inverter. Your SOLAR power inverter is designed to automatically shut down in the
event of a power overload. This feature protects the inverter in the event that you attempt to power a device with a
power demand exceeding the inverter's capacity.
In the event the automatic shut down protection occurs or the inverter sounds a continuous audible alarm, turn off
the power inverter immediately. Do not restart the power inverter until the source of the problem has been identified
and corrected.
Powering High Surge Loads
Some types of equipment that utilize an induction motor require extremely high peak power to meet the initial surge
demand of that motor. In some cases, this equipment cannot be powered by the inverter even though the power
requirement of that equipment falls within the operating range of the power inverter.
If a specific piece of equipment that utilizes an induction motor is unable to be started when connected to the power
inverter, set the power display to Voltage Mode and observe the input voltage to the power inverter while trying to
start the equipment. If the voltage indicator nears or goes below 10.5 Volts, this explains why the equipment is failing
to start. Check the state of charge of your power source battery(ies) and all connections to ensure power is being
properly delivered to the inverter. If such a check does not reveal any problems, you may need to upgrade to a larger
battery or group of batteries.
Suggestions When Using Your SOLAR Power Inverter to Power Television and Audio Devices:
Although your SOLAR power inverter is shielded and filtered to minimize signal interference, some interference with
your television and audio equipment may be unavoidable, particularly when they have weak signals. Here are a few
suggestions to improve your reception under these circumstances:
1. Make sure the television/audio antenna on the device produces a clear signal under normal operating
conditions (when plugged into a standard 110 Volt AC outlet). Also, ensure that the antenna is properly
shielded and of good quality.
2. Change the positions of the power inverter, antenna, and tv/audio power cord to see if a change in their
relative positions improves your reception.
3. Isolate the television/audio device, its power cord and antenna cables from the power inverter and 12 Volt
power source by running an extension cord from the television/audio device power cord to the inverter.
4. Coil the television power cord and the power cables running from the 12 Volt power source to the power
inverter.
5. Attach a "Ferrite Data Line Filter", available at most electronic supply stores, to the television/audio device
power cord. More than one filter may be required.
