2. About Solar charge controller:-
You must buy a solar charge controller if you are buying a solar
power system because it will help the system battery to extend
its life. Solar charge controller controls the electricity flow and
also works on stabilizing the voltage of the device. Thus it as
important device you must buy to increase the health of the
battery of solar power system.
3. Regulating the electricity of solar charge
controller:-
At the time of over discharging when a 12 volt
battery drops below the 11 volts. The low voltage
disconnected circuit gets disconnected loads. It
just reconnects the loads only the time when the
charge is being accumulated. Photovoltaic panels
work on the mechanism of pumping the current
into the reverse direction which results in slight
discharge from the battery. It is easily preventable
with the help of a charge controller. In most of the
controllers charge current passes through the
semiconductor as it helps to pass it only one
direction.
4. Working of a PWM controller:-
For the PWM charger working mechanism which
is two stages regulation the controller initially
holds the voltage to the unit of safe maximum
point until the battery gets fully charged. After
that it drops he voltage lower for sustaining the
trickle or finish charge. Two stage regulations
are very important for the battery which is used
now a day. It maintains full charge but
decreases the loss of water and stress.
5. Metering and display of the charge
controllers:-
Solar Charge controllers come in various kinds of
displays. The range starts from single red light
displays to digital displays which are used for
displaying the unit of voltage and currents.
These displays are useful for monitoring the
battery charges. This display is also used in the
car which shows the amount of power in and
out of the system. It also indicates the
approximate charge of the battery of your car
and the limit results.
6. Electronic protections provided by this controller
are:-
Overcharge protection is enabled in the battery at the end of
the charge voltage
For boosting the charge voltage deep charge protection is
used.
Reverse polarity for the load is protected with module and
battery reconnection voltage.
It has a deep discharge protection with an automated
electronic fuse.
Less risk of short circuit as the module and load are
protected.
Circuit is protected without the battery.
The degree of overload protection is high.
Battery is over the voltage shutdown
Module input is protected from the over voltage protection.
7. Specifications of this product:-
