AC - DC Sine Wave Inverters
The technology of using an inverter to obtain
a 230V or 115V power supply from a battery is not new. Until now,
however, the results were less than perfect as most inverters could
only produce an output voltage that was not sine wave formed and
the efficiency of the products were low. Power conversion manufacturers' have optimised the
inverter technology, resulting in the availability of a superb range
of high efficient sine wave inverters.
Our product range of pure sinewave inverters are a special
breed of power inverters which produce a clean sinewave equal or
better in quality than what you would expect from wall mains. Regular
power inverters only approximate what you would get from wall mains,
and this could result in damage to sensitive equipment.These inverters
are suitable for critical applications such as servers and timers
which depend on a consistent 50 Hz or 60Hz frequency, and professional audio
equipment which can be susceptible to the buzz in standard inverters.
The Solenttech range of Inverters series consist of pure sine wave inverters that convert
battery voltage to AC voltage for all AC devices.
We also provide modified sinewave inverters
for less critical applications. These Solenttech inverters allow
you to operate 230 volt AC or 115AC equipment almost anywhere at anytime.
All you need is a DC power supply or battery. This range of inverters
use switch mode technology, the battery DC voltage is converted at
high frequency, regulated and rebuilt as 50Hz AC OR 60Hz mains voltage.
This technology makes the product compact, lightweight and affordable,
as no heavy transformer is required. The range starts from 100w through to 40KW.
Inverter Chargers
Solenttech Inverter chargers incorporate a powerful pure sine wave inverter, a sophisticated battery charger (with adaptive charge technology), a solar panel regulator and a high-speed AC transfer switch all integrated into a single compact enclosure.
The pure sine wave output of the Inverter Charger means it will safely power all types of equipment, PC's, Laptops, Stereo's, DVD's, LCD TV's, etc...
In the event of a grid failure, or shore/generator power being disconnected, the inverter is automatically activated in less than 20 millisecond and takes over supply to the connected loads allowing them to continue to operate without disruption.
The battery charger can draw considerable power from the generator or shore supply and therefore the power sharing control is incorporated to automatically reduce the charger power when other loads are in use, thus preventing shoreline overload trips.
Battery Chargers
& Charging Equipment
There are many types of chargers available today.
They are usually rated by their start rate, the rate in amperes
that the charger will supply at the beginning of the charge cycle.
When selecting a charger, the charge rate should be between 10%
and 13% of the battery¦s 20-hour AH capacity. For example,
a battery with a 20-hour capacity rating of 225 AH will use a charger
rated between approximately 23 and 30 amps (for multiple battery
charging use the AH rating of the entire bank). Chargers with lower
ratings can be used but the charging time will be increased.
As a rule we recommend using a 3-stage charger.
Also called "automatic" or "smart" chargers.
These chargers prolong battery life with their well programmed charging
profile. These chargers usually have three distinct charging stages:
bulk, acceptance, and float.
Charging batteries properly requires administering
the right amount of current at the right voltage. Most charging
equipment automatically regulates these values. Some chargers allow
the user to set these values.
The majority of our range of chargers will provide
Short Circuit Protection, Reverse Polarity Protection, High Temperature
Protection, Constant Current Bulk Charge, 3 Stage Charging and a
Constant Voltage Float feature to hold the battery at peak charge without overcharging!
Even the best batteries will suffer a reduction
in output or ultimate life if inferior systems are used for essential
routine charging and maintenance.
We offer a large range of chargers designed for
traction batteries and traction 2Volt cells. Nominal output voltages
include 12v, 24v, 36v, 48v, 72v, and 80v, with this choice and current
outputs between 10A and 180A all you charging requirements can be
catered for.
Solar Technology
Solar technology and the environment: Solar power technology is the energy technology
of the future. Through supply of solar power technology we can give
people all over the world the opportunity of producing and consuming
clean electricity. Solar energy helps to reduce carbon dioxide emissions
into the environment and will conserve resources of fossil fuels.
Electricity is produced from sunlight using what
are known as Photo-Voltaic Cells. These cells are thin glass-like
plates of silicon material that produce electricity between the
front and back surface when sunlight falls on the front surface.
The electricity is produced from the visible portion of sunlight,
not the heat part. The more intense the light the more electricity
it produces. Even under cloudy condition's electricity can be produced
although in lesser quantities. The electricity that the solar panel
produces is placed into storage batteries for later use.
There are three basic types of solar panels:
monocrystalline, polycrystalline, and amorphous. All three types
of panels are made up of an array of individual cells.
Monocrystalline Cells: Made using cells saw-cut from a
single cylindrical crystal of silicon, this is the
most efficient of the photovoltaic (PV)
technologies. The principle advantage of
monocrystalline cells are their high efficiencies,
typically around 15%, although the manufacturing
process required to produce monocrystalline
silicon is complicated, resulting in slightly
higher costs than other technologies.
Multicrystalline Silicon:
Made from cells cut from an ingot of
melted and recrystallised silicon. In the
manufacturing process, molten silicon is cast into
ingots of polycrystalline silicon, these ingots
are then saw-cut into very thin wafers and
assembled into complete cells. Multicrystalline
cells are cheaper to produce than monocrystalline
ones, due to the simpler manufacturing process.
However, they tend to be slightly less efficient,
with average efficiencies of around 12%., creating
a granular texture.
Thick Film Silicon: Another multicrystalline
technology where the silicon is deposited in a
continuous process onto a base material giving a
fine grained, sparkling appearance. Like all
crystalline PV, this is encapsulated in a
transparent insulating polymer with a tempered
glass cover and usually bound into a strong
aluminium frame.
Amorphous Silicon Cells:
Composed of silicon atoms in a thin homogenous
layer rather than a crystal structure. Amorphous
silicon absorbs light more effectively than
crystalline silicon, so the cells can be thinner.
For this reason, amorphous silicon is also known
as a "thin film" PV technology. Amorphous silicon
can be deposited on a wide range of substrates,
both rigid and flexible, which makes it ideal for
curved surfaces and "fold-away" modules. Amorphous
cells are, however, less efficient than
crystalline based cells, with typical efficiencies
of around 6%, but they are easier and therefore
cheaper to produce. Their low cost makes them
ideally suited for many applications where high
efficiency is not required and low cost is
important.
Other thin films:
A number of other promising materials such as
cadmium telluride (CdTe) and copper indium
diselenide (CIS) are now being used for PV
modules. The attraction of these technologies is
that they can be manufactured by relatively
inexpensive industrial processes, certainly in
comparison to crystalline silicon technologies,
yet they typically offer higher module
efficiencies than amorphous silicon. New
technologies based on the photosynthesis process
are not yet on the market.

developments in the photovoltaic field.Even today the design life
