Hybrid Solar PV System
Basics
A hybrid solar power system is combination of on grid solar system and off grid solar system. It has battery backup in it to store power and it also have the ability to feed surplus electricity into main grid.
Hybrid system is fully automatic, programmable and custom engineer system. This allows a smart hybrid combination of all energy sources to you.
- Solar panel will run your connected load.
- Meanwhile extra electricity will be stored in the solar battery.
- Surplus electricity will be fed back to the electricity grid by hybrid solar inverter.
System Components:
Though a hybrid system is a combination of On Grid and Off Grid systems, there are two major components.
- Battery Bank:
Similar to the Off grid system, once the battery bank is fully charged, it will stop receiving power from the solar system. The energy from the battery can then be discharged and used to power your home, usually during the peak evening period when the cost of electricity is typically at it’s highest.
Battery-Based Grid-Tie Inverter:
Hybrid solar systems utilize batter-based grid-tie inverters. These devices combine can draw electrical power to and from battery banks, as well as synchronize with the utility grid.
Currently, for the vast majority of homeowners, tapping the utility grid for electricity and energy storage proves to be significantly cheaper and more practical than using battery banks and/or backup generators.
- The meter and electricity grid:
Depending on how your hybrid system is set up and whether your utility allows it, once your batteries are fully charged excess solar power not required by your appliances can be exported to the grid via your meter. When your solar system is not in use, and if you have drained the usable power in your batteries your appliances will then start drawing power from the grid.
