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 expensive,
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
the battery configuration and capacity are the most important electrical power decision to
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 maintain.

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 loads).
