General
opinion over the last few years was that the Quasi-sinewave inverter
was dead, and the pure sine-wave inverters would rule the world
(an opinion not shared by Sterling) sales of quasi-sinewave inverters
have continued to out-grow sales of sine-wave, proving that there
is plenty of life left in this technology. The principle reason
is that most of the equipment such as mobile phones, TVs drill chargers
and all that type of equipment which used to have a problem working
with quasi-sinewave tends now work fine on quasi-sine as the effected
equipment now tends to use switch mode power supplies in there design
which works fine with quasi sine wave . This meant that rather than
the problems getting worse over the years the problems have diminished,
however this is not to say that the odd microwave, drill vacuum
cleaner would not work (if there is a thyristor control circuit
employed then this can still be a issue ) but there is no question
this is becoming more rare as the years go past, plus its still
usually a lot cheaper to replace a £ 35 microwave to a different
model which will work rather than spend £ 700 on a sine wave
model to make it work.
Sterling
has invested in a new range of quasi-sine inverters because they
are smaller, lower cost, offer better performance, are more efficient
and more reliable than sine-wave. At Sterling have always found
the quasi-sinewave inverter more than adequate for general requirements
in boats and vehicles. There is still the odd appliance, such as
washing machines, where quasi-sinewave inverters simply do not work,
but all in all they do a great job – especially considering
their cost. With this in mind, we have made a new range of DIGITAL
quasi-sine inverters called the Pro Power Q. The idea behind this
was to push forward this technology and bring in some new features.
The most obvious change in this new inverter is its style, tough
aluminum extrusion with great looking plastic end caps, euro and
British sockets are on all this range ,enabling the unit to be compatible
across Europe without problem. The new extrusion design has allowed
us to reduce the size of the 1000-2500 watt units by nearly 40%,
but still offer their full power and even better performance over
the previous models.
All Sterling
inverters are rated for continuous use with all the usual overload,
over voltage and low voltage cut outs. All the inverters come with
a DC cable and 24 kt gold connectors in order to prevent battery
terminal corrosion. Now with multi-speed fans for low noise. Inverters
of 1000, 1800 and 2700 watts come with a remote control.

Auto switch mean's, All you have to do is flick a switch and all
mains sockets work from the inverter. (this system is protected
so if you plug into mains there are no nasty shocks)
Available
