EFFICIENCY.
Any inverter is totally reliant on batteries to provide the
DC Input, a power source which is not endless. So it makes
sense that you can extract every last possible watt from your
batteries in the most ecomonical fashion. The batteries which
will support your Everest will in some cases be worth a lot
more than your inverter, so it makes sense to preserve them.
Clever use of microprocessors allows the printed circuit board
(PCB) component count to be kept as low as possible, the PCB
which is manufactured using the latest in surface mount technology
is extremely small, minimising any unnecessary losses.

Many
inverters have a very small overall efficiency, but can still
claim high peak efficiency. Thr Everest range can do both, for
example the SEAP-48-3K8 achieves an amazing 91% at just 5% of
load and has a peak efficiency of a staggering 95%.
The power stage of the Everest utiliseslow RDS ON mosfets to further
reduce switching losses, whilst a very efficient torodial transformer
maintains maximum power transfer to the output.
If monitoring features recommend some of the very good and cost
effective independent monitoring units availabletoday, these can
be connected into your system without upsetting the critical reliability
and efficiency of your inverter and overall system.
They say rules are made to be broken, the SEAP-12-2K0 is evidence
of that. There are times when a load such as a kettle or a large
microwave oven just run from 12 volts, but rather than say it
can't be done we've found a way to do it. By use of a super heavy
wiring and massive bus bars both internally and externally Solar
Energy Australia can provide you with 2000 watts of continous
sinewave power from 12 volts, but be warned, your batteries have
to be up to it.
FIELD
SERVICEABLE.
In the unlikely event that something goes wrong and a repair is
required, simply contact your local authorised dealer who in most
cases can repair your Everest quickly and without costly freight.
The Everest range of DC to AC inverters from Solar Energy Australia
are amongst the most practical and functional inverters available
today. This range of inverters may not have a fancy array of flashing
lights and bells and whistles, and may not be the best looking
inverteres available, but it is the features that are hidden that
make the Everest range of inverters truly attractive solution
to your remote power needs.
Practicality is considered the No 1 design criteria of these products,
to make sure your inverter delivers the goods when it really counts.

PROTECTION
AND SAFETY.
To ensure the safe reliable operation at all times, all SEA
inverters are protected against battery voltage out of range,
AC overload or short circuit and thermal overload. |

The SEAP-12-2K0, SEAP-24-3K0 and SEAP-48-3K8 also have a set of
contacts which will close just before the inverter shuts down on
the low DC volts, this output can be used for starting an auto start
generator or sending an alarm.
SIMPLE
AND FUNCTIONAL INSTALLATION.
Mounting of an Everest inverter could not be easier, don't waste
time building shelves, the 3mm all aluminium chassis mounts simply
onto any suitable vertical surface, using the mounting templete
provided and 4 holes on the chassis.
That word 'practicality' comes to mind again when we talk about
wiring an Everest inverter. Glands are provided to access the internal
din rail, 3 terminal blocks are provided to simply hard wire straight
into. To further improve the installation flexibility, the hard
wire terminals can be replaced on site with AC breakers or RCD safety
switches, there is an even changeover contactor on the din rail.
Simple pole fillers can be pushed out of the front cover to allow
the AC breakers or RCD to penetrate the lid.
BATTERY
DRAW - how long does my battery last?
SEA Inverters are extremely efficient, and therefore use very little
power to run their internal circuits. An SEA inverter will only
use as much power as the appliance needs.
Here
is a simple formulae to help you work out how long your fully charged
battery will last.
In this formulae the following is assumed:
o ACWatts = figure written on
the rating label of the AC (240) appliance.
o Watts = Volts x Current(Amps)
o AH = Ampere Hour capacity
of the battery.
o DC I = DC Current drawn
by the appliance
o Only 50% of the batteries
capacity will be used to allow it to recover.
For
example, a 16 inch TV running on 130AH battery
has an AC draw of 67 watts.
If
you recharge your battery during this time, with solar panels or
driving the vehicle then this time will be extended.
* Use a figure of 20 if your battery voltage is 24v DC.
