Systems
which allows you to store your solar power in batteries for use when the power
grid goes down or if you are not on the grid.
Hybrid systems provide power to offset the grid power whenever the sun
is shining and will even send excess power to the grid for credit for later
use. Provides power for your critical loads when the power grid is down is
known as Off
Grid Inverter.
Solar Power System
is the use of the sun’s energy either directly as
thermal energy (heat) or through the use of photovoltaic cells in solar panels
and transparent photovoltaic glass to generate electricity .
Standard
photovoltaic solar panels are the most efficient application of photovoltaic.
However, photovoltaic glass allows generation from surfaces like building
windows that were previously incapable of anything but passive solar energy and
also enables other options, like color choices. Other technologies include
low-tech solar heaters created from recycled cans that provide an inexpensive
source of heat.
The
power source is PV, wind, hydro, fuel, or utility grid. Its purpose is to keep
your batteries properly fed and safe for the long term.
Charge Controller
basic functions are quite simple. Charge controllers block reverse current and
prevent battery overcharge. Some controllers also prevent battery over
discharge, protect from electrical overload, and/or display battery status and
the flow of power.
The
control of battery charging is so important that most manufacturers of high
quality batteries (with warranties of five years or longer) specify the
requirements for voltage regulation, low voltage disconnect and temperature
compensation. When these limits are not respected, it is common for batteries
to fail after less than one quarter of their normal life expectancy, regardless
of their quality or their cost. A good charge controller is not expensive in
relation to the total cost of a power system. Nor is it very mysterious. I hope
this article has given you the background that you need to make a good choice
of controls for your power system.
These
charge controllers give approx 30% more power than a PWM charger and you can
connect high voltage panels to lower voltage battery banks.
In
a normal charger the battery acts as a resistor reducing the amount of power
you can get out of the panels, these chargers use Multi Power Point Tracking
(MPPT) which keeps 2 separate circuits for the panels and batteries allowing
upto 30% more power to be collected from the panels.
Using
higher voltage on the panel side will also benifit by less volt drop and can
use thinner cables. On large arrays we
run everything at 100V - 150V that is MPPT Charge
