Solar Charge Controllers
The basic objective of charge controllers for solar panels is
to regulate the flowing electric charge to a battery group from
the photovoltaic cells. Different kinds of charge controllers
are available in the market. With the help of an efficient charge
controller, one can control DC electricity while they can also
charge a group of batteries from solar panel at the same time.
AC Charge controllers are also available in the market that will
facilitate the charging of batteries from an AC circuit or household
circuit current. If you are using wind turbines for generating
electricity, you will have to use diversion load controllers that
will also help you monitor micro-hydro systems and their battery
charging process. However, a suitable temperature sensor will
be needed to facilitate better and optimal performance of battery
charging.
Each type of charge controller can be used for different possible
applications. The following list will explain more about solar
charge controllers for PV panels:
Solar Charge Controllers: these are mainly used to control
and optimize the flowing charge from solar panels while providing
security for batteries in solar electric systems against any possible
mistake that may cause problems.
Solar Lighting Controllers: these are advanced devices
that can offer a programmable controller for lighting along with
proper solar charge controller. These controllers can be used
to significantly eliminate the requirement of a load controller
or timer. They can simply put an off to the solar lighting system
at a pre-scheduled time.
AC Charge Controllers: A DC battery bank can be directly
charged up by using these charge controllers as they can efficiently
use an AC source like a homely circuit or a petrol generator.
There is a wide range of models of AC charge controller that may
allow swiftest possible charging and may also offer different
voltage outputs and inputs.
Constant Voltage Regulators: these electrical devices
can be used to offer a stable output while taking a variable input
DC voltage. Depending on the type and efficiency of converter,
the output voltage can be higher or lower in comparison with the
input voltage.
Dump Load Controllers: these charge controllers can either
be solar charge controllers or they may also act as a DC load
controller or they can be used as a diversion load controller.
However, they can perform only one of those any tasks at a time.
The Role of Temperature
Sensors
The temperature sensors of a battery can be used with a charging
source such as charge controller for solar energy to gather information
about temperature of the battery. This offers a better protective
system for battery while facilitating appropriate charging in
accordance with the battery temperature. Almost all manufacturers
of charge controllers for solar panels also produce temperature
sensors and offer them separately in market.
Every renewable energy resource system offers continuous service
to collect power while storing it in batteries. This is the reason
why it is necessary to use appropriate charge controller with
each system. A charge controller for solar energy is used to provide
better security for your batteries against the chances of being
overcharged while blocking any incidence of reverse current and
will also protect the system against hazardous high temperatures.
Thus, solar charge controllers can be used to protect the whole
solar energy system. However, suitable temperature sensors should
be used with all solar panel charge controllers or other continuous
resources.
