Hybrid
These types of solar systems generate power in the same way as a common grid-tie solar system but use special hybrid inverters and batteries to store energy for later use. This ability to store energy enables most hybrid systems to reduce peak loads where the customer has billing demand charges and to also operate as a short term backup power supply during a blackout.
Advantages of Hybrid Solar Systems
1. Less expensive than off-grid solar systems
Hybrid solar systems are less expensive than off-grid solar systems. You don’t really need a backup generator, and the capacity of your battery bank can be downsized using Off-peak electricity from the utility company when power is cheaper.
2. Smart solar holds a lot of promise
The introduction of hybrid solar systems has opened up many interesting innovations. New inverters can let homeowners take advantage of changes in the utility electricity rates throughout the day.
​
Solar panels happen to output the most electrical power at noon – not long before the price of electricity peaks. Your home and an electric vehicle can be programmed to consume power during off-peak hours (or from your solar panels).
​
Smart solar holds a lot of promise. The concept will become increasingly important as we transition towards the smart grid in the coming years.

Equipment for Hybrid Solar Systems
Typical hybrid solar systems are based on the following additional components:
-
Charge Controller
-
Battery Bank
-
DC Disconnect (additional)
-
Battery-Based Grid-Tie Inverter
-
Bi Directional Power Meter (provider by wire service provider)
Battery-Based Grid-Tie Inverter
Hybrid solar systems utilize battery-based grid-tie inverters. These devices combined can draw electrical power to and from battery banks, as well as synchronize with the utility grid.
