Grid-Tie With Battery Backup Systems

Grid-tie with backup systems are designed to function when the electric utility grid is unreliable or when the constant operation of some devices is essential. With this type of system, you’ll be able to move one step closer to total energy independence.

Typically, these systems use a bank of batteries paired with solar energy panels to supply power to the building whenever the electric utility grid is down.

For this type of system, DC power from the solar array travels to a charge controller that constantly monitors the level of charge to the batteries. When the batteries are low on charge, electricity passes to them. If they are fully charged, then the electricity is diverted to an inverter and then the electrical wiring of your structure.
