Grid Tie, Wind, Solar PV Hybrid System
Hybrid Systems - Utility Connected with Battery Backup: A
combination of grid tie, solar PV
and wind turbine system with
battery bank, these applications have the advantages of both.
They are connected to the utility grid in case the weather is
insufficient for the solar or wind system, but they also have batteries
to store electricity in case the utility grid goes down
as well. The
design and installation of these systems is more complicated and
but they are the most effective in providing constant, reliable electricity.
Typical grid tie, wind, solar PV hybrid diagram:
Wind / Solar PV Hybrid Systems Include:
1. PV Array: A number of PV panels connected in series and/or in
parallel giving a DC output
out of the incident irradiance. Orientation
and tilt of these panels are important design
parameters, as well as
shading from surrounding obstructions.
2. Wind turbine: which is installed on top of a tall tower, collects
kinetic energy from the wind and converts it to electricity that is
compatible with a home's electrical system.
3. Solar controller: control battery bank charge and discharge
reasonable and safety.
4. Wind controller:
5. Battery bank: can be a single battery or multiple batteries
connected together to create essentially one large battery of the
required voltage and amp-hour capacity. In some ways
configuration and capacity are the most important electrical power
make, and a wise choice can help guarantee a steady supply
of electrical power as well
as a system that is simple to operate and
6. Inverter: A power converter that "inverts" the DC power from the
panels into AC power.
7. Loads: Stands for the network connected appliances in the building
that are fed from the inverter (AC loads), or from the battery bank (DC
