DC Grounding:
The Sine Wave Inverter has a lug on the rear panel labeled
Chassis Ground. This lug is used to connect the chassis
of the inverter to your DC ground as is required by
regulations for some installations. Depending on where
the Sine Wave Inverter is installed, follow the
instructions below that correspond to your installation
location.
3. Sine Wave Inverter Operation
This section details how the unit functions as an inverter,
provides information on the control panel, and describes
operating limits for inverter operation.
3.1 Principles of Operation
The Sine Wave Inverter converts power from the batteries
in two stages. The first stage is a DC-to-DC converter,
used to raise the low voltage DC input to high voltage
DC. The second stage is the actual inverter stage, taking
the high voltage DC and converting it to a precise, true
sine wave AC output.
The DC-to-DC converter stage uses modern high
frequency power conversion technology that eliminates
the bulky, low frequency (50/60 Hz) based transformers
found in inverters using older technology. The inverter
stage uses advanced power semiconductors that provide
excellent overload capabilities.
3.2 Output Waveform
The AC output waveform of the Sine Wave Inverter is a
“true sine wave” with typically 1% Total Harmonic
Distortion (THD). Figure 6 illustrates the output
waveform from the inverter. This waveform is nearly
identical to your utility-supplied power and in some
cases where utility power is poor, the Sine Wave Inverter
delivers cleaner, more precise AC power.
There are many advantages of true sine wave over other
wave forms delivered by other inverters:
• AC powered equipment is designed to operate with
true sine wave. Many loads will perform better when
connected to the Sine Wave Inverter.
• motor loads start easier
• reduced stress on surge protection circuitry within
the equipment means potentially longer equipment life
Many advantages of true sine wave are also due to the
absence of the sharp-rising edges of waveforms prevalent
in either modified sine wave or square wave inverters.
Some of these advantages are:
• reduced interference in audio or electronic
equipment, especially those that use less complex
internal power supplies
• significantly reduced in-rush current into capacitive
loads and reduced stress on the output devices of
the inverter, potentially lengthening equipment life
• motor loads generally operate cooler and quieter
without the extra harmonic distortion generated by
a modified sine wave.
