Description:

1.Basic Structure

The home photovoltaic energy storage inverter is mainly composed of the following parts:

DC Input Terminal: It is connected to the photovoltaic modules and receives direct current (DC).

Inverter Module: Converts direct current into alternating current (AC).

AC Output Terminal: Outputs alternating current for use by household electrical appliances or for grid connection.

Energy Storage Module: Connected to the energy storage battery, it enables the storage and release of electrical energy.

Control Unit: Responsible for the monitoring and control of the system to ensure the coordinated operation of each module.

2.Working Process

The working process of the home photovoltaic energy storage inverter can be divided into the following steps:

Photovoltaic Power Generation: The photovoltaic modules convert solar energy into direct current, which is transmitted to the inverter through the DC input terminal.

Electrical Energy Conversion: The inverter module converts direct current into alternating current, which is supplied to household electrical appliances through the AC output terminal or used for grid-connected power generation.

Electrical Energy Storage: When the power generated by the photovoltaic system exceeds the household electricity demand, the energy storage module stores the excess electrical energy in the energy storage battery.

Electrical Energy Release: When the power generated by the photovoltaic system is insufficient, the energy storage module releases electrical energy from the energy storage battery to supplement the household electricity demand.

3.Intelligent Control

The home photovoltaic energy storage inverter is usually equipped with an intelligent control system. It can monitor the power generated by the photovoltaic system, the status of the energy storage battery, and the household electricity demand in real time, and automatically adjust the conversion and storage of electrical energy to improve the efficiency and stability of the system. For example, when the electricity price of the power grid is high, the system can preferentially use the electrical energy in the energy storage battery to reduce the electricity cost; when the electricity price of the power grid is low, the system can feed the excess electrical energy into the grid for power generation to increase the revenue.
