Solar Inverters
Emerson Introduced Grid connected Solar Inverters ( Liebert Energy Export Unit (EEU) , which be Synchronized to grid. It is now available up to 100Kw as a single unit. Solar bi-directional Inverters with battery back up is also available (Liebert Energy Storage Unit). DSP based MPPT design ensure most efficient use of the solar panels used along with it. Liebert ESU is single / three phase output, bi-directional inverter system. ESU operates in parallel with the grid utility. Solar Photo voltaic panels convert solar energy into electrical energy as DC power. This DC power is used to charge the batteries through a charge controller and also used for the load through inverter.
Liebert EEU is single / three phase output inverter, with Grid interactive feature. Solar Photo voltaic panels converts solar energy into electrical energy as DC power. This DC power becomes input for the EEU inverter. The inverter converts it into conventional AC power, and with its state of the art Grid
synchronization design, this AC power is fed to the supply grid.
LEDs are another option to save /generate Power, where power is already available.use of LEDs can help in utilizing the power efficiently for lighting applications
Introduction
to LED Luminaries
Power
LEDs are the latest addition to the various
type of Luminaries available for lighting
purposes,
LEDs are having
many unparalleled features and benefits over
other luminaries available in the market. LEDs
are solid state lights called Light Emitting
diodes, which converts current in to light
directly. In all other types of light sources
, light is produced through some process.
With Incandescent lamps current is used to
heat the filament ( as a space heater) to a
great temperature and light emits (as a
byproduct) when the temperature goes very
high. In Tube lights and CFL lights light is
produced when the electrons falls on some
special materials coated on the surface of the
tube. But in LEDs light is produced directly
from Electric current.
Since
lights are one of the biggest power users we
must pay close attention to what kind of
luminary we use. If all the lights are
replaced with efficient versions, lot of power
will be saved and it will solve the scarcity
of power to a greater extend.
Use
of LEDs for lighting purposes makes the use
of Photo Voltaic Panels a viable proposal as
the size of PV panels and Batteries can be
small for same a system of same capacity.
LEDS
are having the following features and
advantages
- LEDs
Luminaries are highly efficient light
sources. LEDs consumes atleast 50% less
power compared to existing luminaries.
Power Saved is the Double the power
generated. And that is the foremost reason
why we must use LED luminaries. When we use
LEDs we produce power and give to
Electricity board free of cost .
- Very High
Efficiency .Power saving which can be
achieved by using LED Lightings is about 40%
to 80%, depending on the applications
- LED can be
used for selective lighting, only the
required area will be lit, which in-turn
increases the efficiency at the same time
improve the ambiance
- LEDs are
best suitable for Theam lightings
where we can control brightens, direction
and colors as per the situation/
requirements
- Life of LED
are very high in comparison with other
luminaries and it goes above 50000 hours.
- LEDs are best
suitable where back up is required for
lighting. The size of Inverter and Battery
can be Halved and the re coring cost on
batteries can be saved if we convert all the
important and continuously required
luminaries in to LEDs
- LEDs work on
DC power and hence LEDs can be put on
batteries directly with out any inverter
increasing efficiency flexibility in the
usage of power.
- Maximum
saving is possible , if we replace all the
Luminaries which work all the 24 hours. The
more we use , the more we save. Best
suitable for Flood Lights, Street Lights,
Factory shop floor lightings. Factories,
Hospitals, Bus stations/ Railway stations,
Aerodrams etc are the places where 24hr
lighting is required.
- LED contains
no toxic elements , disposal is easy .
Unlike other type of luminaries , which
contains mercury and pollute the
environment.
- Use LEDs ,
Save power and can help to reduce the
global warming
We can give LED lighting
for the following categories. A wide range
of innovative LED lighting for a variety of
applications, including indoor, outdoor and
handheld lighting.
