I believe I am guilty of promoting free energy on the off grid homestead, and during the summer months it appears that way. However, during the winter months cloudy skies make solar energy creation improbable, and it's the battery bank that keeps the home's electricity going from day to day. When the fog and inversion … Continue reading Off Grid electricity is NOT free.

To take the batteries from 35% of discharge to 100% full is about four hours of generator time on our 6,800 watt Rigid generator from Home Depot. … Continue reading Electricity: When the backup generator is called upon…
