Designing a residential wind or solar power system requires many engineering considerations. One of the biggest decisions is whether to design a grid-tied (GT) or off-the-grid (OTG) system. This decision is a prime motivator in design of the battery storage system. A professional can design and install an appropriate system for each unique situation.
A typical GT system feeds excess electricity back into the power grid, running the consumer’s meter backwards. If the grid is available, it is also used to supply power to the home if necessary. OTG systems rely totally on themselves and backup generators to supply electricity needs. Either system may use batteries to store energy, but going OTG requires battery storage.
