Wellsee solar light controller Fetures:


1. It can prevent the battery from over-charging and over-discharging.

2. It can prevent reverse charging (the battery charges the solar panel).

3. It can prevent reverse connection of the battery and solar panel.

4. It will start up the lighting system in the evening automatically according to the intensity of the light.

5. It will shut down the lighting system according to the time setting or shut down automatically when it is dawn.

6. It has a LET indicator of the working condition of charging and discharging

We produce different kinds of 12V/24V/48V 6A-60A solar charge controllers including:
WS-C series PWM solar controllers for PV system
WS-MPPT series solar controllers  for PV system
WS-L series PWM solar controllers for solar lighting system
WS-AL series solar light-adjusting controllers for solar lighting system
WS-ALMPPT series solar high efficiency controllers for solar lighting system


Solar light controller (Street light controller)

Solar light controllers

 are smarter versions of the mechanical or electronic timers previously used for street light ON-OFF operation. They come with energy conservationoptions like twilight saving, staggering or dimming. Also many street light controllers come with an astronomical clock for a particular location or a Global Positioning System (GPS) connection to give the best ON-OFF time and energy saving.


Some intelligent solar light controllers also come with Global System for Mobile Communications (GSM), Radio frequency (RF) or General Packet Radio Service (GPRS) communication, user adjusted according to latitude and longitude(low cost type), for better street light management and maintenance. Many street light controllers also come with traffic sensors to manage the lux level of the lamp according to the traffic and to save energy by decreasing lux when there is no traffic. America, Canada, India and many other countries have started introducing street light controllers to their road lighting for energy conservation, street light management and maintenance purpose.


Solar light controllers can be expensive in comparison with normal timers, and can cost between $100 and $2500, but most of them return the investment between 6 months and 2 years. As the equipment's lifetime is 7 to 10 years it saves energy and cost for some years.
