Off-grid systems are similar to grid-tied systems, but rely on batteries to store energy for night and cloudy days. To design off-grid systems, a very thorough load analysis is required, and decisions must be made about how long you want to run in cloudy periods, what energy-saving appliances you will need, what kind of well pump you can have, what size and kind of back-up generator, and other considerations. It’s exciting, but pretty involved. Empowered Energy Systems has installed a number of solar systems for homes and cabins. Contact us to start planning an off-grid system.
