PN series SOLAR/WIND POWER STREET LIGHT CONTROL SYSTEM
Overview
The controller is the most important component of this street light
control system, its reliability decides the amount of maintenance
work, the performance of the controller effects the life time of
the system directly, espacially, the life time of the battery.
Overcharge and depth of discharge both will damage the battery. As
a result, the cost of the system maintenace would be increase
rapidly as the battery is changed frequently. "All functions of
this system would be effected by it, that is way the controller
must have optimal performance." Our controller is designed by
adopting the micro-computer chip and non-contact control
technologies, can precisely control the process of battery
chraging/discharging, so that the life time and performance of the battery
is maxiimised. It also has various protecting functions.
According to the compositon of the system or mean of access the
energy it can be divided into:
- PNS series solar power street light controller is applied in solar
PV system, coordinating the solar penels, battery and load.
- PNW series wind turbine street light controller is applied in wind
power generating system, coordinating the wind power, battery and
load.
- PNWS series wind-solar complementary street light controller is
applied in solar panels and wind turbine complementary system,
because the wind and solar resources are distributed differently in
differrent areas, seasons and weather conditions.
Applications
Applicable for areas without power grid that is using solar power
lighting and the control of the bateery discharge system in urban
multi-functional powers. Street lights, landscape light, grass
lights, viewing lights, traffic lights, bus stop lighing and
outdoor advertisement lighting.
The PCS solar power charge controller is the device that charges
the energy from solar power into battery. By adopting the
micro-computer chip and non-contact control technologies, with
various protecting functions, its controlling ability effects the
battery's life time and system efficiency directly.
