Solar
street light operation is relatively simple, is a charge and discharge
process, the daytime solar panel power supply to the lamp holder at
night, the daily cycle of this process, but if the solar street lamp
failure, such as lighting time is shorter lighting is not bright , How can we quickly identify the reasons for it?
First
of all need to know whether the lamp lighting time is short or not
bright, if the lighting time is short that the configuration of the lamp
or the battery panel is not enough power generation, the reason may be
configured unreasonable configuration is relatively small, may be
attached to the battery panel A
relatively thick layer of dust, the situation in the river area is more
common, lighting in the winter lighting time is short, continuous
cloudy days short, out of this situation to clean the battery board can
be, according to the attachment degree of ground handling You can.
The
second is not bright, the lighting does not shine the situation is more
concentrated in the controller is broken or the battery is broken, led
lamp damage is relatively small, damage to the battery board is also
less, if the controller is a problem, Check
method is that we use the voltmeter to measure the voltage of the
battery plate and the battery voltage, if the sun in the day the
situation of the voltage of the battery panel 12v above description of
the battery is no problem, if the battery voltage is 10v or more battery
is normal of.
Then
we can consider for a new controller to see, after the replacement of
lamps in 1 to 2 days after the lighting is the description of the
controller problem, the general battery panels and batteries are normal
does not light the situation is relatively small, if we measured The
voltage of the battery plate in the day less than 10v, then we need to
detect whether the battery cable is good, if the wiring is intact, and
the battery or a low voltage, this may be a problem with the battery,
but Such a situation is very small, most of the situation is focused on the battery.
The
battery voltage is lower than 10v, the general situation is the first
choice for the controller problems, resulting in battery power loss and
can not be fully charged, the second is the battery quality times, the
use of long lead to internal resistance is too large, can not normal
charge Discharged.
In
short if the light does not shine we first have to consider changing
the controller, if the light is not found for a long time, then we
suggest that replace the battery (for a long time does not shine, the
battery is certainly damaged). Recommended reading: wind on solar street lamps have an impact?
