The energy storage system can play a backup and transition role in the case that the photovoltaic power generation cannot operate normally, such as at night or in cloudy and rainy days when the battery array cannot generate power. The amount of energy storage capacity depends on the demand of load. Enough energy storage systems can ensure the quality and reliability of power output. The EBULENT solar energy storage device at home can save money on electricity bills and "cut the peaks and fill the valleys". At the same time, the equipment has an emergency power supply function, to ensure users from sudden power failure.

The project adopts "solar photovoltaic off-grid power generation" technology and off-grid photovoltaic power generation mode. This project requires a 10KW photovoltaic power generation system with a matching 25KWh battery energy storage system. Based on the installed capacity of 10Kwp, the average effective sunshine time is 6 hours, which can be calculated to generate about 1200 KWH of electricity per month and about 14,400 KWH of electricity per year.
The project adopts off-grid power generation and relies on energy storage batteries for energy storage. During the day, solar panels convert solar energy into electricity and store it in the energy storage battery. At night or when there is no sun on rainy days, the energy storage battery supplies the load. Off-grid solar power station is mainly composed of solar panels, busbar, DC box, inverter, energy storage battery, steel support structure and wire.
Specific working principle:
During the day, under the irradiation of sunlight, the direct current generated by the solar cell module is transferred to the AC220 alternating current through the off-grid inverter to supply power to the household load. The excess power is stored in the energy storage battery for the power supply at night, cloudy and rainy days. Under special circumstances: when photovoltaic and energy storage batteries do not meet the power supply requirements, the mains supply can be supplemented to ensure uninterrupted power consumption.
1, photovoltaic module: the light energy into direct current energy, through the all-in-one to charge the battery, or directly inverter into AC power supply to the load.
2. Mains or generator: The AC input terminal is connected to supply power to the load and charge the battery at the same time.
If the mains or generator is not connected, the system can run normally. In this case, the load power is provided by batteries and photovoltaic modules.
3. Battery: The role of the battery is to ensure the normal power consumption of the system load when the solar energy is insufficient and there is no mains electricity.
4, household load: can access a variety of household, office load, including refrigerators, lamps, TV, fans, air conditioning and other AC load.
