This 12kW system is ideal for a household of three to four people, providing 10 kW of power from the inverter. It is quite similar to the power supplied by grid providers, with a maximum demand of 40A, approximately 10 kW. The system can generate over 20 kWh per day on average during winter, potentially reducing or eliminating the need for generator use. The battery bank is sufficient to last about 24 hours.
