overview
Hybrid solar systems generate power in the same way as a common grid-tie solar system but use special hybrid inverters and batteries to store energy for later use. This ability to store energy enables most hybrid systems to also operate as a backup power supply during a blackout, similar to a UPS system.
Some people who are interested in solar power gravitate towards the idea of being completely removed from the grid. However, remaining connected to the grid and investing in a battery backup system will actually provide more benefits.
