MNRE Model 1-4 (CFL)
A solar home lighting system (SHS), converts solar energy into electricity and provides a comfortable level of illumination in one or more rooms of a house. There are several SHS models featuring one, two, or four CFLs (Compact Fluorescent Lamps). The system could also be used to run a small DC fan or a 12-V DC television along with the CFL (s).
The SHS consists of a PV module of 18, 37 or 74 Wp capacity, a lead-acid battery (of 12 V and 20, 40 or 75 AH capacity respectively) and CFLs of 9 W or 11 W rating. The system is designed to work for three to four hours daily, with an autonomy of three days i.e. the system can function for three consecutive cloudy days. A PV module is usually mounted on the roof of the house or any other convenient place so that it is exposed to direct solar radiation throughout the day, avoiding any shadow. The module converts incident solar radiation into electricity, which, in turn, charges the battery. The battery is placed inside the house. The battery provides power to the CFLs, and/ or the television/ fan as required. A charge controller prevents overcharging and deep discharge of the battery.

Electronic Protections |
 |
Adequate protection is incorporated under no load i.e. when the lamps are removed and the system is switched ON. |
|
The system has protection against battery overcharge, deep discharge condition. |
|
Fuses are provided to protect against short circuit conditions. |
|
Protection for reverse flow of current through the PV module(s) is provided. |
|
Electronics have proper temperature compensation for proper charging of the battery throughout the year |
|
|
Other Features |
The system is provided with 2 LED indicators: a green light to indicate charging in progress and a red LED to indicate deep discharge condition of the battery. The green LED glows only when the battery is actually being
charged (It stops glowing when the battery is fully charged). |
