Solar Home Systems
A Solar Home System
consists of a Solar charge controller, a battery, a solar module and
the load. The load is always a DC load is always a DC load in standard
Solar Home Systems. The charge controller is connected directly to
the battery. The module and the load are connected directly to the
charge controller terminals. Charge controllers regulate the complete
energy flow within the system. The battery is charged by the current
from the solar module. If the battery is full, the charge controller
limits the current to the battery to protect the battery from over
charging. If the load discharges the battery, the controller also
cuts off the load before the battery is empty, in order to prevent
a dangerous deep discharge of the battery. Charge controllers also
have an integrated intelligent battery monitoring system. The optimal
charging strategy will be chosen depending on the need of the battery.
In Solar Home Systems the charge controller is the central device-all
functions of the system are influenced by this controller.
