The charge controller employs an intelligent two step charging algorithm. In the initial stage the battery cells are charged from its nominal value to a boost level. On reaching
the boost level the solar module is disconnected. When the battery voltage falls below the required voltage, the solar module is reconnected & the charging process continues.
High Frequency Inverter The built in circuit has a high frequency inverter which inverts DC power available from battery into high frequency AC (alternate current) power to light the CFL.
Battery The battery is an essential component in the SPV system.
This is where the energy is stored during the day and used in the night. The type of battery used in the streetlight is low maintenance lead acid battery.
Compact Fluorescent/LED Lamp CFLs/LED are second & third generation lighting solutions for today & these are highly light effcient. These lamps have several advantages over conventional incandescent bulbs. CFLs/LED are energy efficient and long lasting (8000/40000hrs),and produce less heat.
