1. The system configuration and Con-inverter package automatic switch function:
When the power grid without electricity, photovoltaic energy transformation after machine directly for the use of the load, excess power automatically stored in the storage battery;When lack of photovoltaic (pv), by the battery to load with photovoltaic power supply;
2. The system according to the daily power consumption 15 kWH calculation;
3. The average effective sunshine 4.9 h/d;
4. The system peak capacity in 4kW.
5. The battery is full of 50.4 kWh energy storage;
6. Total power load is not more than 4 kw (more than 4 kw, the system will automatically switch to the mains supply lectricity load).
