Grid Tie Solar System With Battery Backup
In a normal grid-tied solar system, if the grid goes down for any reason, so does your solar system. We also know that in an off-grid solar system, we can power our entire home with a bank of deep-cycle batteries. Want the best of both worlds? The solution is a grid-tied solar system with backup power, or more commonly known as a "hybrid solar system." Backup power can come from a battery bank, or some type of backup generator. The battery bank does not need to be as large as in the case of an off-grid system, since it can be set up to only power "critical" loads, such as your refrigerator and lights. Here is the general layout of a hybrid solar system:
The benefits of hybrid energy systems over on-grid systems is that they can provide for energy when your system is not producing energy. In order to meet safety compliance standards, all on-grid solar energy systems turn off in the event of a power outage, some people are surprised to find out that their solar energy system cannot provide them with power in these situations.
