18W Solar Street Light

18W all in one

We have established ourselves as a leading name of superior quality Solar Street Light. These are raised light sources which are powered by photovoltaic panels generally mounted on the lighting structure or integrated into the pole itself. The Solar Street Light photovoltaic panels charge a rechargeable battery, which powers a fluorescent or LED lamp during the night. These lights turn on and turn off automatically by sensing outdoor light using a light source. Solar streetlights are designed to work throughout the night. Features: Automatic turn off and on. Photovoltaic panels. Raised light sources. Microcontroller based PWM charging with inbuilt solar street light with the following features: Constant Current Phase: all charging current available is used to charge the battery. Constant voltage Phase: Constant battery voltage towards end charge to present excessive gassing Float Stage (below gassing voltage to avoid electrolyte loss) Constant Current Driver. Driver efficiency > 90% Reverse polarity protection without the use of fuse to ease up installation in spite of the human error Battery charge indicator for different levels of the battery should be present on the fixture, indicating at least 4 levels of battery for easier maintenance. Apart from this, low battery and charging indicators should also be present Parallel backup LED pads with each LED should be present so as to replace the solar LED luminary easily in case one of them fails in future Applications: Street Lighting, Gathering and events, Corridors, factory Premises, Housing colony, Rural Village, Panchayat, Protections, Battery Over Charge, Battery Deep Discharge, Solar Panel Reverse Polarity, Battery Reverse Polarity, LED overcurrent watchdog.
