How Power Inverters Work
Power inverters utilize a two-step method to convert 12 Volt direct current (DC) power into 115 Volt AC power. In
the first step, the power inverter uses a DC to DC converter to increase the DC voltage from the original 12 Volts
DC to 145 Volts DC. In the second step, the power inverter converts high voltage DC power into 115 Volt AC power
using advanced micro-circuitry which we refer to as Sonic Compression technology.
It is this Sonic Compression technology that enables SOLAR power inverters to accommodate strenuous "peak
power" and "continuous power" demands, while at the same time, providing the assurance of automatic overload
protection.
The modified sine wave produced using our Sonic Compression technology has a root mean square (RMS) voltage
of 115 Volts. Most AC voltmeters are calibrated to measure the RMS voltage of a pure sine wave. For this reason,
most voltmeters will not measure the output voltage of your power inverter correctly, typically showing an output
about 20-30 Volts below the actual output. To accurately measure the output voltage of your SOLAR power inverter,
use only a voltmeter identified as a "True RMS" reading voltmeter.
Things to remember when operating your SOLAR power inverter:
Loose connections can result in a severe decrease in voltage and may cause damage to the wires and insulation in
the power inverter. Always check that all connections are correct and secure prior to powering the inverter and any
device connected to it.
Failure to make a proper connection between the power inverter and the 12 Volt power source can result in a
reverse polarity condition. A reverse polarity condition will blow the internal fuse(s) of the inverter and may cause
permanent damage to the inverter. Damage caused by a reverse polarity condition is not covered in the warranty.
When making the connection between the Positive terminals of the power inverter and the 12 Volt power source, it
is possible that you may create a spark. For this reason, it is critical that both the power inverter and the 12 Volt
power source not be positioned in the vicinity of flammable fumes or gases.
When attempting to power any device using your inverter, monitor the temperature of the device for approximately
10 minutes. If the device being powered becomes abnormally warm, disconnect it from the power inverter
immediately.
When using an automobile or marine battery to power the inverter, start the vehicle's engine every 30 to 60 minutes
and let it run for approximately 10 minutes to recharge the vehicle's battery. We recommend that the device being
powered by the inverter, as well as the inverter itself, be turned
When your power inverter is not in use and turned
when connected. As a result, we recommend that you disconnect the power inverter from the 12 Volt power source
when not in use.
Use of an extension cord between the SOLAR power inverter and the device being powered will not significantly
decrease the power generated by the power inverter. For best results, do not use an extension cord longer
than 50 ft.
SOLAR Power Inverter Safety Features
Your SOLAR power inverter is equipped with automatic shut off protection which will be activated if any of several
unsafe operating conditions exist. In the event that any of the following conditions occur, the Fault Indicator light
will turn on and the power inverter will shut down:
1. The power input from the 12 Volt power source drops to 10.0 Volts. (When the power from the 12 Volt power
source drops to 10.5 Volts, an extended audible alarm will sound, warning you that your power source is low.)
2. The power input from the 12 Volt power source exceeds 15.0 Volts.
3. The "continuous power" demand from powered devices exceed the power rating of your inverter.
4. The "peak power" demand from the powered device exceeds the peak power rating of your power inverter.
5. The circuit temperature within the power inverter exceeds 149˚F (65ºC).
In the event the automatic shut down protection occurs or the inverter sounds a continuous audible alarm, turn
the power inverter immediately. Do not restart the power inverter until the source of the problem has been identified
and corrected.
