MEASURING THE AC VOLTAGE
This inverter's AC output is a modified sine wave (MSW) 115 volts AC. Your
household AC output is pure sine wave. The comparison of modified sine wave and
household AC is shown in the figure below.
(Pure sine wave)
This modified sine wave has a root mean square (RMS) voltage of 115 volts. Most
ordinary AC voltmeters are calibrated to read "average" voltage and assume that
the AC waveform will be a pure sine wave. These meters will not correctly read
MSW voltage, and will display about 20 to 30 volts too low. Any multi-meter
identified as "TRUE RMS" will accurately read MSW correctly.

User's Manual—Read before using this equipment
BASIC OPER ATION
• Turn ON the power switch that is located at the front of the inverter, and
the green LED indicator will light up as an indicator that the unit is working.
• Plug your appliance(s) into the AC socket(s) at the front of the inverter.
PL ANNING THE INVERTER SYSTEM
Any large wattage inverter system requires planning before installation. There are
several steps to the planning process so the user must determine the following:
• Maximum inverter wattage required.
• Operating time (run time) needed between battery recharges.
• Battery bank capacity in amp-hours.
• Charger requirement to charge batteries within a practical time.
• Distance between battery bank and inverter.
DETERMINING M A XIMUM APPLIANCE WAT TAGE
Maximum AC Appliance Wattage is the first factor in planning battery and
charging systems. Some background:
Large microwave oven specifications list cooking power (watts) and appliance
power. Appliance power is the AC load the inverter has to supply.
Most other electrical tools, appliances and audio/video equipment have labels
that list the unit's power requirements in watts. If the tool or device is rated in
amps, multiply the amps by 115 (115V AC) to determine the watts. For example,
a power tool rated at 4-amps will draw 460 watts.

Determine the wattage of each appliance you need to simultaneously operate.
Add all of the appliance wattages to obtain an estimated "total watts" number.
Remember to consider the start-up surge that motorized appliances will cause.
