In recent years, smart home solar energy storage systems have become increasingly popular. It can continuously provide green power to households day and night. Through solar power generation, there is no need to worry about high-tiered electricity prices, saving electricity bills, and at the same time, it can better ensure the high quality of life of each family.

 

During the day, the home solar energy storage system absorbs solar power and automatically stores it for night load use. In the event of an unexpected power outage, the system can automatically switch to home backup power in time, ensuring the normal operation of lighting, electrical appliances, and other equipment systems at all times. During low electricity consumption periods, the battery pack in the home energy storage system can be recharged by itself to be used as backup power during peak power or power outages. In addition to being used as an emergency power source, the home energy storage system can also balance the electricity load, thus saving household savings. Electricity expenses. The smart home photovoltaic energy storage system is similar to a micro energy storage power station, and its operation is not affected by the city's power supply pressure.

 

What is a home solar energy storage system?

A home solar power station energy storage system is a system that combines a solar photoelectric conversion system with an energy storage device, which can convert solar power into storable electrical energy. Such systems allow home users to generate electricity during the day and store excess energy for use at night or in low-light conditions.

 

Classification of home photovoltaic energy storage systems

 

There are currently two types of home energy storage systems, one is the grid-connected home energy storage system, and the other is the off-grid home energy storage system.

 

Grid-connected home energy storage system

It consists of five major parts, including a solar cell array, grid-connected inverter, BMS management system, battery pack, and AC load. The system uses a hybrid power supply of photovoltaic and energy storage systems. When the mains power is normal, the photovoltaic grid-connected system and the mains power supply power to the load; when the mains power is out, the energy storage system and the photovoltaic grid-connected system jointly provide power. The grid-connected home energy storage system is divided into three working modes. Mode 1: Photovoltaics provide energy storage and the remaining electricity is connected to the grid; Mode 2: Photovoltaics provide energy storage and some users use electricity; Mode 3: Photovoltaics only provide part of the energy storage.

 

Off-grid home energy storage system

It is independent and has no electrical connection to the power grid, so the entire system does not require a grid-connected inverter, and photovoltaic inverters can meet the requirements. Off-grid home energy storage systems are divided into three working modes. Mode 1: Photovoltaics provide energy storage and user electricity (sunny days); Mode 2: Photovoltaics and energy storage batteries provide user electricity (cloudy days); Mode 3: Energy storage The battery provides users with electricity (in the evening and rainy days).

 

Whether it is a grid-connected home energy storage system or an off-grid home energy storage system, it is inseparable from the inverter. The inverter is like the brain and heart of the system.
