What’s the difference between off-grid, grid-tied, and hybrid solar systems?

Off-grid systems operate independently from the utility grid. Grid-tied systems connect to the grid. Hybrid systems combine both for flexibility and backup.

How does solar energy flow through my system?

Sunlight hits your solar panels, which send power to your inverter. The inverter converts it to usable electricity, which is stored in batteries or used directly.

Can I monitor my system’s performance?

Yes. OffGrid Power systems include monitoring tools that show energy production, battery levels, and generator cycles.
