Solar Backup for Whole House with Battery

Battery Backup for the House

“Reasonably” priced systems to power your house or gear.  Keep in mind a WHOLE solar system can run many $50,000 to $90,000 and that is NOT our goal. Choose your level of comfort.

EVERY HOME should have 1-3 of these small units.

Your PHONE is a critical part of information and communication, but usually goes dead in hours. We use these small chargers almost every day.

How did you determine the amount of backup batteries for your home? I can look at my max usage and my solar panels. Can these units be continually charged by solar and discharge at the same time with night time recharge from the grid? If so, how did you do that?
