Sunpower Generator
OPERATION MANUAL
Lifeway solar Sunpower Generator is a
unique and innovative product running on
solar energy - sunlight. A German
Technology indigenized to suit our climate
in India.
Today Generators are running either on
diesel, petrol or kerosene. Lifeway Solar's
Sunpower Generator will run on Sunshine
and having advantages of zero noise
pollution, no air pollution etc. Sunpower
gives you clean green energy from the
nature itself. Sunpower generators are
easy to keep inside the room; the
photovoltaic modules which are fitted on
the rooftop will harness the sunlight. DC
power produced from the panel is
transmitted through thick copper cable to
charge controller then to the tubular
batteries for storage. During day time or in
the night according to the demand this
energy is drawn either as DC or convert
in toAC through sinewave Inverter which
givesthesufficientpowertotheutilitieslike
lamps, fans, refrigerators, T.V etc.

Components of the
Generator
Solar Panel:
Solar photovoltaic panel will harness sun
light and produce DC electricity.
Solar Charge Regulator:
Thechargeregulatorwillcontrolthebattery
and recharge the battery with the power
from the solar PV module.
Solar Battery:
The battery will get charged during the day
time and provides the energy during night.
Sinewave Inverter:
If there is a need for AC power, then an
inverter is needed to transform / convert
the DC power into AC power.
Consumer/ Equipments:
Fan, Lamps like CFL or LED Luminaries,
Television, Fridge, Washing Machine etc.
Sunpower Generators are available in
various capacities 500VA, 1 KVA, 2 KVA,
4 KVA. Other than 12V/ 500VA, 1 KVAand
2 KVA are in 24 V and 4 KVA in 96 V.

Cable from Panel to Battery:
For photovoltaic system 12 V and 24 V
systems, the maximum Voltage drop on a
cable should not be more than 0.7 V.
Therefore this table can be used to
dimension the length of a DC cable.

Warrantee
Lifeway provides one year guarantee for
manufacturing defects and four years warrantee on
entire system. 10 years for Photovoltaic modules
andtwoyearsforExide battery.AMCwillbeginfrom
the second year onwards. Annual maintenance will
be provided by our local distributors to the clients.
As a thump rule Solar irradiation over India is 1900
KWH/M2 /peryear.Howeveritchangesdepending
on the climate change. From 10 A.M to 4 P.M is
considered as the harnessing time. When we are
calculating a day's power production then we have
to monitor that particular day's weather
condition also.
Maintenance and Operation Phase
1. WashPVarray,duringsummerdays,whenthere
is a noticeable buildup of dust, tree leaves on it.
2. Periodically inspect the system to make sure all
wiring and supports stay intact.
3. On a sunny day near noon, review the output of
the system (assuming the array is clean) to see
if the performance of the system is close to the
previous year's reading. Maintain a log of these
readings so you can identify if the system
performance is staying consistent, or declining
too rapidly, signifying a system problem.

OPERATION MANUAL
Before starting PV system testing
1. Check that non-current carrying metal parts
are grounded properly. (array frames, racks,
metal boxes, etc. are connected to the
grounding system)
2. Ensure that all labels and safety signs
specified in the plans are in place.
3. Verify that all disconnect switches (from the
main AC disconnect all the way through to
the combiner fuse switches) are in the open
positionand tageachboxwithawarningsign
to signify that work on the PV system is in
progress.
4. Verify that all combiner fuses are removed
and that no voltage is present at the output
of the combiner box.
5. Visually inspect any plug and receptacle
connectorsbetweenthemodulesandpanels
to ensure they are fully engaged.
6. Check that strain relief's / cable clamps are
properly installed on all cables and cords by
pulling on cables to verify.
7. Check to make sure all panels are attached
properly to their mounting brackets and
nothing catches the eye as being abnormal
or misaligned.

8. Visually inspect the array for cracked
modules.
9. Check to see all wiring is neat and well
supported.
10.Check home run wires (from PV modules to
combiner box) at DC string combiner box
to ensure there is no voltage on them.
11.Recheck that fuses are removed and all
switches are open.
12.Connect the home run wires to the DC string
combiner box terminate in the proper order
and make sure labeling is clearly visible.
Verify that the only place where the AC
neutral is grounded is at the main service
panel.
13.Ck the AC line voltage at main AC
disconnects is within proper limits (220 - 230
Volts AC).
LIFEWAY SOLAR SUNPOWER
GENERATOR START UP TESTS
1. Be sure that the system is off before
proceeding with this section.
2. Test the continuity of all DC fuses to be
installedintheDCstringcombinerbox,install
all string fuses, and close fused switches in
combiner box.

3. Check open circuit voltage at DC disconnect
switch to ensure it is within proper limits
according to the manufacturer's installation
manual.
4. If installation contains additional DC
disconnect switches repeat the step 4
voltage check on each switch working from
the PV array to the Lifeway sun power
generatorDC disconnectswitchclosingeach
switch after the test is made
5. At the point consult the Lifeway Sun power
generator manual and follow proper startup
procedure.
7. Confirm that the operating voltage is within
properlimits according tothemanufacturer's
installation manual.
8. After recording the operating voltage at the
Lifeway Sun power Generator close any
open boxes related to the system.
9. Confirm that theLifeway Sun power
Generator is producing the expected power
output on the supplied meter.
10.Provide the house owner with the initial
startup test report.

ACCEPTANCE TEST
Ideal testing conditions are midday on cloudless
August through May however cloudy and rainy
daystobeavoided.Thistestprocedureaccounts
for less than ideal conditions and allows
acceptance tests to be conducted on sunny
summer days like in March,April and May. Due
to climate change 2008 we had summer shower
continuously in April 2008. So this fact also we
have to consider in the coming years.
1. Check to make sure that the PV array is in
full sun with no shading whatsoever. If it is
impossibletofindatimeduringthedaywhen
thewholearrayis in full sun,only that portion
that is in full sun will be able to be accepted.
2. Ifthesystemisnotoperating, turnthesystem
on and allow it to run for 15 minutes before
taking any performance measurements.
WARNING: IF POLARITY OF ONE SOURCE
CIRCUIT STRING IS REVERSED, THIS CAN
START A FIRE IN THE FUSE BLOCK
RESULTING IN THE DESTRUCTION OF THE
COMBINER BOX AND POSSIBLY ADJACENT
EQUIPMENT.
