SOLAR STREET LIGHT :
SED POWER Solar Street
Lights are immensely useful as stand alone source of light on streets
and in premises, gardens and industrial
complexes.
- These conform to MNES
specifications.
- It is a packaged solar powered
outdoor lighting system which provides easy and quick way of tapping the
solar power.
- The systems are very easy to
install needing no special skills, tools or expertise.
- They provide a steady source
of light in areas where conventional sources of mains utility are
erratic, unreliable or unobtainable.
- They are independent and
self-contained and hence need no extra wiring or cables.
- They save on costly
transmission losses

SOLAR LANTERN
:
A Solar
Lantern from SED is an excellent solution for light at homes where mains
utility is unavailable. Based entirely on MNES specifications, it has
the following salient features.
|
SALIENT FEATURES:
Entire
electronics housed on a single PCB with connectors for easy
replacement without any need of desoldering.
It contains a high frequency,
27KHz, pure sine wave inverter to drive 4-pin, 7 W CFL with pre-heat
technique to avoid the blackening of ends.
Inverter is protected against
accidental short or open circuit conditions.
Charge
controller is shunt type regulating with temperature compensation.
Very low drop
out voltage to utilize the full potential of solar panel is achieved
by a Schotkey diode which also prevents reverse current from battery
to panel at night.
Protections are provided
against reverse battery connection, over charge and deep discharge of
battery and short circuits.
Idle current is less than 1 mA
for prolonged shelf storage.
Lumen output is constant over
entire operating range of battery voltage.
Two indicators are provided to
show the charging state and battery low condition by two LEDs.
Sealed maintenance free
battery of 12V /7 Ah is fitted inside to give over 4 hours of backup
every day.
10W solar panel with suitable
cable for connection is provided.
Over 90 % of rated Lumen
output is guaranteed after 1000 cycles of operations with 2 minutes on
followed by 4 minutes off period as is mandatory by MNES.
CFL is fitted in base down
configuration with 360 degrees orientation.

SOLAR HOME LIGHTING:
In standard package, two
fans and two CFL of 11/9W supplied as electrical gadgets. 2x37W SPV
panels for charging 70Ah/12V battery. The system can be custom made as
per requirement by employing solar grade inverter of very high
efficiency upto 1KW capacity. The number of batteries and panels
depending upon the individual load requirement and back-up time desired
on daily basis. Very useful for places where mains supply is erratic or
unavailable.A SOLAR
UPS (pdf) operating
entirely on solar energy and suitable to drive the loads like PCs,
Lights, Fans, TV and such gadgets is also available in different
capacities.
