Pure Sine vs. Modified Sine Wave Inverters
Both photovoltaic modules and batteries use direct current (DC)
power. We need an inverter to change the direct current to alternating
current (AC) in order to utilize the power being generated in a home. In
order to maximize energy output, it is important to select an inverter
with the following characteristics:
- High efficiency
- Low standby losses
- High surge capacity
- Low harmonic distortion
One way of classifying inverters is to distinguish the AC output waveforms - these are
pure sine wave and
modified sine wave.
All
grid tied inverters are pure sine (true sine) inverters, hence the
grid, by nature, is a pure sine wave electricity source. The importance
of pure sine wave or modified sine wave inverters may be apparent
especially for off grid applications such as RV, boat or cabins. Off
grid inverters are used for connecting a battery source or a solar PV
system to an AC load such as a home applicance, a laptop charger, a TV.
Pure sine wave inverters
are used to operate sensitive electronic devices that require high
quality waveform with little harmonic distortion. In addition, they have
high surge capacity which means they are able to exceed their rated
wattage for a limited time. This enables power motors to start easily
which can draw up to seven times their rated wattage during startup.
Virtually any electronic device will operate with the output from a pure
sine wave inverter.
Modified sine wave inverters
(modified square wave or step wave) approximate a pure sine waveform.
Modified sine wave inverters are designed to satisfy the efficiency
requirements of the photovoltaic system while being less expensive than
pure sine waveform inverters. These inverters are capable of operating a
wide variety of loads; electronic and household items including but not
limited to TV, VCR, and satellite receiver, computers, and printers.
