IMPORTANT:
To avoid risk of injury, DEVDEEP SOLAR strongly recommend
the services of a qualified
professional who is trained in occupational health and safety procedures, to clean solar
electricity panels.
Introduction
Congratulations on the purchase of your solar electricity system. Not only are you protecting
yourself from current and future price rises of electricity, you are also saving significant CO2
emissions which helps reduce global warming and climate change.
Your system is designed to meet all Indian Standard conditions, regulations and codes. Although
it is very low maintenance, it must always be remembered that the system generates electricity and
we strongly recommend that you do not attempt to service it yourself unless you are suitably qualified.
Your safety is our primary concern .
Owner Safety for Maintenance
For your safety, we recommend that you do not attempt any servicing yourself unless you are
suitably qualified.
The solar panels work best when clean. Regular rainfall or washing with a hose will maintain their
cleanliness. If they do become excessively soiled they can be cleaned with cold water. DEVDEEP
SOLAR strongly recommend that you avoid climbing onto the roof and use the services of a qualified
professional who is trained in occupational health and safety procedures.
Shading of the solar panels will affect efficiency and performance. Plant and tree growth that may
cause shading at various times of the year, should be monitored and dealt with as required. Likewise,
leaves, bird droppings and other debris coming to rest either on or around the solar modules should
be carefully removed.
If you notice your system is not operating correctly, please check the TROUBLE SHOOTING
chapter on page 7 and if necessary call 9726879009 immediately and we will help you to diagnose
your problem and can arrange to send a technician to resolve it if necessary. If you need to shut
down the system, please follow these steps in this order –
1. Switch OFF the Solar Supply Main Switch in the Main Switchboard or Meter Box
2. Switch OFF the AC Isolator and DC Isolator adjacent to the Inverter
Following these steps will safely isolate the solar array. To switch it back on, you simply reverse the
procedure.
Always remember that your system will be generating electricity during daylight hours and care
should always be taken to eliminate the risk of electric shock. Refer to the OPERATING INSTRUCTIONS
on page 5 for more information.

How Your DEVDEEP SOLAR System Works
The following illustration and narrative explains how your solar electricity system works –
1. The solar electric modules are usually fitted to the roof. The number of modules will depend on
the nominal size of your system and, collectively, they are known as the solar array. The solar
array converts sunlight into direct current (DC) electricity.
2. The DC electricity is fed to the Inverter which is normally accessible at ground level. The Inverter
converts the DC electricity to Alternating Current (AC) electricity which is compatible with the
electricity supplied to your house from the grid. Most Inverters have a digital readout so you can
monitor information such as the amount of solar electricity produced, etc. Refer to the separate
Inverter owner’s manual for more information.
3. Depending on Local Regulations, Your Solar system may be connected to the grid on a Net
Metering System. With Net Metering, only the Electricity not First consumed by the House will be
Exported to the Grid .
If you have an Old Electro - Mechanical Meter (with the spinning disk), this will need to be replaced
with a Bi- Directional Meter able to record the electricity you both import and export.
Your Electricity Retailer will read your Meter monthly and Bill you for your electricity consumption.
Credit will be paid for Electricity exported to the grid at the rate of ₹3.24 per Kwh . This is known as a
Feed-In Tariff.
System Performance
During daylight hours, your system will be generating electricity at varying rates depending on the
amount of sunshine. The more sunlight falling on the solar array the more electricity is generated,
variable factors such as cloud cover, seasonal solar angle variations, shading or soiling of the solar
array will have an effect on the electricity output. Note that you do not need to change your energy
usage lifestyle to correspond with your solar system. Your energy consumption will be supplied by
both solar and the grid.

IMPORTANT NOTE:
Disclaimer of Liability: Despite the Instructions and Recommendations provided in this Manual,
the Actual use and maintenance of the Solar Power System is beyond the control of DEVDEEP
SOLAR. Therefore, DEVDEEP SOLAR does not assume any responsibility and expressly
disclaims Liability for Loss, Damage or Expense associated in any Way with the Installation,
Use, or Maintenance of the Solar Power System.
Operating Instructions
Your solar electricity system is designed for automatic operation without need for user
intervention. There are no moving parts or need for the owner to interact with its operation.
In the case of Mains Grid Supply Failure the Inverter will immediately and automatically be
disabled. This is known as “anti-islanding” and it protects linesmen from an electric shock from
your system when they assume the grid is “dead”. Once the grid power has been restored, the
Inverter will be automatically re-enabled.
If you notice your system is not operating correctly, please check the TROUBLE SHOOTING
chapter on page 6 and if necessary call 9726879009 Immediately and we will diagnose your problem
and send a technician to resolve it if necessary.
Operating Safety Instructions
• Do not Attempt to Service the system unless you are Fully Qualified to do so. To service any
Electrical connection you have MUST be a Licensed Electrician.
• All Service work must be carried out in strict compliance with all Local and National Electrical
Regulations and Standards.
• Review and follow all Safety Instructions supplied with all components of your DEVDEEP
SOLAR electricity system. Further information can be found at
http://www.devdeepelectricals.com
• Do not Attempt to Clean or Come in contact with the surface of a solar module with broken
glass. This could result in a Dangerous Electric Shock.
• Be Aware that power may be present at any point in Electrical Circuits despite the Opening of
Circuit Breakers or Isolators.
• Circuit Breakers can trip Automatically if problems occur. If the circuit breaker is switched
back to the closed or “on” position and it immediately trips back to the open or “off” position
there is a problem.
• Appropriate Precautions must be taken when working on rooftops or at heights in accordance
with Local and National occupational health and safety regulations.

Trouble Shooting
The Inverter displays LED lights and/or screen displays to monitor the normal operation and fault
conditions of the system. The occurrence of a problem within the system will usually be indicated by
the Inverter. The Inverter user manual contains a trouble shooting chapter which will explain these
lights and displays.
Please Read the Trouble Shooting Chapter carefully and then precisely follow the Instructions
Given. If these fail, please call 9726879009 immediately and we can assist to Locate a Qualified
Technician to Resolve your Problem .
