Hybrid systems are usually a combination of photovoltaics
with wind turbines and/or generators running on diesel
or biofuels. Power generated by the PV array during
the day is stored in the battery bank through an
energy manager, which controls the complete system.
How It Works
The SunTechnics wind generator starts generating
power when wind reaches the cut-in speed of
3m/s and the output is stored in the battery
bank.
This energy is drawn by the electrical loads
through the inverter, which converts DC power
into AC power. The inverter has in-built protection
against short-circuit, overheating, low battery voltage and overload.
The battery bank is designed to feed the loads
up to a certain number of days with no sun or
wind, depending upon the system requirement.
The wind turbine is self-regulated with a patented
pitch control mechanism which guarantees a stable
energy output during strong winds. It also ensures
storm protection and is much lighter than conventional
small wind turbines.
During very windy periods, the excess energy
is dissipated through a dump load, which can
be used for heating purposes.
