How It Works

An accurate load audit is the foundation of off-grid system sizing. List every appliance, its wattage, and daily usage hours. A refrigerator runs its compressor about 8 hours per day at 150W. LED lighting uses 80% less than incandescent. The average off-grid home uses 5-15 kWh per day compared to 30 kWh for a grid-connected home.
