Hybrid solar systems combines the best from grid-tied and off-grid solar systems. These systems can either be described as off-grid solar with utility backup power, or grid-tied solar with extra battery storage.
Advantages of Hybrid Solar Systems
- Less expensive than off-gird solar systems
Hybrid solar systems are less expensive than off-grid solar systems. The capacity of your battery bank can be downsized. Off-peak electricity from the utility company is cheaper than diesel.
Equipment for Hybrid Solar Systems
Typical hybrid solar systems are based on the following additional components:
Solar Array
Charge Controller
Battery Bank
DC Disconnect (additional)
Battery-Based Grid-Tie Inverter.
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.
