Introduction 

 

Congratulations! You have purchased one of the most sophisticated and reliable power inverters on the market today. 
Incorporating some of the latest technological developments, it will give years of trouble free operation for your truck, boat, R.V. 
or other. 
 
In order to get the most out of your inverter, the installation procedure must be followed carefully and it must also be properly 
used. Please thoroughly read this manual before installing and using your new inverter. 

It is important to pay special attention to 

the CAUTION and WARNING statements in this manual as well as on the inverter.

 Should the inverter be exposed to rain, 

moisture, or strong impact, have it inspected by a qualified technician before use. 
 

WARNING!  

The electrical current at the entrance and exit of your inverter may cause severe personal injury; 
make certain that you have read and understand all the parts of this manual before installing and 
using your inverter. 

 
WARNING! 

The inverter produces an electrical current similar to that found in most North American homes, with 
all the accompanying dangers. Be sure to install the product out of the reach of children. 

 

1.1

 

Disclaimer 

Electrical codes vary depending on location and the type of installation. Electrical installations must meet local and national wiring 
codes and should be performed by a qualified electrician. 
 
The inverter’s specifications are subject to change without notice. 
 

1.2

 

Output waveform 

The AC output of your inverter is regulated to 120 volts and its waveform is called a “Modified Sine Wave.”  It is a stepped 
waveform, suitable for most AC loads, designed to have characteristics similar to sine waves delivered by utility power. Note that 
our modified sine wave output power is much more efficient than the “square wave” generated by other inverters on the market 
today. 
 
The modified sine wave generated by your inverter is designed to have an RMS (Root Mean Square) voltage of 120 volts, the 
same voltage as that coming out of standard household power. Most AC voltmeters are sensitive to the average value of the 
waveform rather than the RMS value. They are calibrated for RMS voltage assuming the voltage waveform is “ pure sine wave.” 
These meters may not read the modified sine wave correctly; they will read about 2-20 volts lower. To read the voltage correctly, 
you must use a true RMS reading voltmeter.

FRONT PANEL 

 
ON/OFF switch: 

The ON/OFF switch turns the inverter’s control circuit ON and OFF. 

It does not disconnect power 

from the inverter; you must disconnect the AC (120 volts) and DC (24 volts) power before 
working on any circuits connected to the inverter.

  When the switch is on but no power is being 

supplied to a load, the inverter draws less than 500 mA. This is a very low current draw but left in this 
state the inverter will eventually drain your batteries until its automatic shut down at 22 volts (see 
4.3). 

 
AC Outlets: 

The maximum output of your inverter is assumed to go through the two AC outlets. HD Models are 
also equipped with one hard wire outlet which can be used as the only output socket.  

 
 

CAUTION! 

Leave in the OFF position during the installation.
