The most commonly observed type of residential solar solution, grid-tied home solar systems operate without batteries. These systems are both cost-effective and straightforward to design and install, as they consist of minimal components and are user-friendly, making them highly favored.

However, the absence of a battery poses a limitation, as homeowners cannot store excess solar power. Stored energy serves crucial purposes during emergencies or blackouts, as well as during periods when solar panels are inactive, such as nighttime. Without a battery, the primary backup source remains the local grid.

Excess electricity generated is typically directed back to the grid, and when needed, homeowners draw power from the grid instead of relying on a battery. Net metering proves beneficial in this setup, allowing homeowners to receive bill credits for surplus power sent to the grid, which can be utilized to purchase power when solar production is insufficient.

In the event of a grid outage, users of grid-tied home solar systems will experience power loss. To ensure safety, inverters automatically disconnect from the utility grid when power outages occur.
