Power System Major Components
stand-alone photovoltaic (PV) systems, charge
controllers regulate the current from the PV
array in order to protect the battery from being
overcharged. In addition controllers regulate
the current to the load, thereby protecting
the battery from deep discharges. The charge
controller is therefore the energy manager in
a stand-alone PV system, ensuring that the battery
is cycled under conditions which do not reduce
its ability to deliver its rated capacity over
its expected lifetime.
procures charge controllers
from world class manufacturers like Digital
Solar Technologies (DST) USA, Morningstar Corporation
USA, Steca Germany etc. Each of the Controllers
address the needs of very specific requirements.
Solar Technologies (DST) specialize in microprocessor
based power system controllers and supply innovative
control solutions for PV/hybrid and grid tied
power systems. DST controllers range from stand
alone PV applications needing advanced controls,
to multiple power source systems requiring varied
I/O monitoring and control needs including data
logging with remote monitoring.
Corporation is a world-leading supplier of photovoltaic
(PV) controllers using advanced technology.
Morningstar's TriStar, ProStar, SunSaver, SunKeeper,
SunLight, SunGuard etc. brands of controllers
have been recognized in the international PV
markets as the most advanced and of highest-quality
controllers have the following characterisitcs
as noted below:
Exceeds all other PV controllers for protection
against lightning surges and the harsh operating
temperatures common to remote PV systems.
Charging: Advanced PWM, constant
voltage, pulsing charge algorithm results
in an increase in battery capacity and operating
Competitive in price with lowest cost controllers
in the industry. The low cost structure, coupled
with advanced features and performance, make
Morningstar's controllers the highest value
products in the industry.
Steca range of charge controllers are ideal
for small and medium solar PV applications.
