① Ensure stable power supply: When the power grid fails or has a blackout, the energy storage battery can serve as a backup power source to meet emergency power needs and keep key household devices such as refrigerators and routers running.
② Improve the utilization rate of photovoltaic power: The photovoltaic power generated during the day that is not consumed can be stored for use at night. This not only reduces dependence on the power grid but also lowers electricity bills.
③ Optimize energy allocation: It intelligently schedules photovoltaic power, the power grid, and the energy storage battery, supports functions like peak - shaving and valley - filling, enabling efficient energy use and refined management of household electricity bills.

① Backup mode: When the power grid fails, the system gives priority to using the battery to power critical loads to ensure the normal operation of electrical appliances.
② Self - consumption mode: It preferentially uses photovoltaic power to supply power to the household and charge the battery, minimizing dependence on the power grid.
③ Advanced mode: It dynamically adjusts the battery charging and discharging strategy according to peak and off - peak hours to maximize electricity cost savings.
④ Peak - shaving mode: When the power consumption exceeds the set value, the energy storage inverter provides the excess power to avoid an increase in electricity bills due to high peak loads.

Yes! It can be connected seamlessly to the existing photovoltaic inverter through AC coupling without the need for redesigning or replacing hardware devices. This design not only reduces the upgrade cost but also allows you to enjoy the multiple benefits of a photovoltaic - energy storage system.

The installation involves electrical wiring and other operations, which is rather complicated. It must be carried out by professional electricians or trained installers to ensure the safe and stable operation of the system.

It is very convenient. The system can automatically charge and discharge without manual operation by the user. Through the mobile APP, users can monitor the system status, power usage, etc. in real - time and remotely set the charging and discharging strategy.

In daily life, you only need to keep the equipment clean and well - ventilated. Generally, no special maintenance is required during the battery's lifespan, and regular inspections by professionals are sufficient. The main maintenance cost is battery replacement. If you choose reliable products with a long battery life, the overall maintenance cost is controllable.

Regular products are equipped with multiple safety protections, such as over - charge, over - discharge, and over - heat protection, which can effectively reduce safety risks. As long as it is installed, used, and maintained correctly, the possibility of explosion is extremely low.

The battery is the main influencing factor. High - quality lithium - ion batteries can have a cycle life of several thousand times. Calculated based on 1 - 2 charge - discharge cycles per day, it can be used normally for about 10 years. Other equipment such as inverters have an even longer lifespan.
