A battery backup system provides the best features from grid-tied solar and off-grid solar.
During times where the utility power grid is up and running, your solar array will act just like a normal grid-tied system saving you money by providing power to your house during the day.
When a utility power outage occurs, your solar battery backup system will automatically switch over to battery power to provide you with the electricity you need. The switching is instantaneous and automatic.
You can also use batteries to provide power during certain times of the day when grid power is more expensive to offset high demand charges. This can help to reduce your electricity bill even further and still have backup power available during electricity outages.
If you already have an existing grid-tied solar electric system, you can retrofit battery backup systems into your existing system no matter how long it has been in service. If you would like to explore your options for battery backup, please read more about batteries or contact us for more information.
