1.0 Introduction

How this Inverter Works
There are two modes of operation associated with the CSW3012-X inverter:
• Inverter Mode:
When the inverter is properly connected to batteries and turned on, the
direct current (DC) from the batteries is transformed into a pure sine wave
alternating current (AC). This AC is similar to the voltage provided by
your utility and is used to power any electrical appliances (i.e., AC loads)
connected to the inverter's output.
• By-Pass (pass-through) Mode:
When an external source of AC power (i.e., utility power or generator) is
connected and qualifi ed on the inverter's AC input, it operates in By-pass
mode. In By-pass mode, the unit automatically closes an internal AC transfer
relay that passes the incoming AC power directly to the inverter's output to
continue powering the connected electrical appliances.

Advantages of a Pure Sine Wave Inverter
Today's inverters come in three basic output waveforms: square wave,
modifi ed sine wave (which is actually a modifi ed square wave) and pure sine
wave (see Figure 1-4).
Modifi ed sine wave inverters approximate a pure sine wave form and will run
most appliances and electronics without any problems. These inverters are
less expensive, and therefore, off er a viable alternative to more expensive
pure sine inverters.
The output of the CSW3012-X inverter—which is pure sine wave—is equal to,
or in many cases, better than the utility power used in your home. Virtually
any electronic device will operate from a pure sine wave inverter. Motors
run cooler, microwaves usually cook faster, and clocks keep better time just
to name a few examples. Without compromising quality or performance,
the CSW3012-X provides you with all the advantages of a pure sine wave
inverter at a much lower cost than many on the market.
