This system includes a 10kW inverter, 20kWh battery storage capacity, and a 10kWp solar panel array. It is designed to supply reliable solar energy for a typical residential home.
This configuration is ideal for U.S. households with moderate to high electricity consumption, providing enough energy for daily use and backup during outages.
Typically, 10kWp solar panels require about 600-800 square feet (55-75 square meters) of roof or ground space, depending on panel efficiency and layout.
Backup duration depends on household energy usage. With 20kWh battery capacity, the system can power essential appliances for approximately 8-12 hours on average.
Peak Shaving: Stores energy during low-cost off-peak times for use during peak hours, reducing electricity bills
