01 What is the photovoltaic system for grid-connected households?

Grid-connected household systems usually refer to the installation of photovoltaic systems on the roof of residential buildings or other buildings with a certain amount of space, and the system will be connected to the conventional power grid to undertake the power supply task jointly.

02 Working mode of grid-connected household photovoltaic system

When there is sunlight, the photovoltaic inverter can convert the direct current generated by the system into alternating current, which is used by the AC load in the household, and the remaining electrical energy can be input into the grid.

In case of insufficient sunlight at night or on rainy days, the photovoltaic system is in standby mode, and the load can obtain electricity from the grid, flexibly switch, and meet the household electricity demand.

03 Advantages of Grid-Connected Household Photovoltaic Systems

Firstly, the energy source of photovoltaic systems for grid-connected households comes from inexhaustible solar energy, which is free and environmentally friendly and does not pollute the environment. At the same time, the system is connected to the grid to ensure the stability and quality of the load power supply;

Secondly, it saves electricity costs and increases additional revenue. After the photovoltaic system generates electricity for household load, there is a surplus that can be fed into the grid to meet the electricity needs of one’s household, while also obtaining electricity sales revenue;

Thirdly, it has the characteristics of generating electricity nearby, connecting to the grid nearby, and using it nearby, effectively solving the power loss problem during boosting and long-distance transportation. It has the advantages of a short installation cycle, low investment, and simple grid connection.

04 Maintenance Techniques for Grid-Connected Household Photovoltaic Systems

Firstly, users should regularly inspect and record the operation of photovoltaic panels and energy storage equipment. Once any problems are found, contact after-sales service personnel promptly.

Secondly, regularly clean the dust and other debris on the photovoltaic panels. It is recommended to clean solar panels in the early morning or late afternoon when the temperature is low. Use a soft and clean cotton cloth or sponge as a cleaning tool, and do not use detergents containing alkali or acid.

In summer, it is advisable to avoid cleaning panels during the highest temperatures to prevent damage to photovoltaic modules due to thermal expansion and contraction; If there is heavy snow on the panel in winter, you should first use a soft tool to push it away, being careful not to scratch or damage the panel.

Thirdly, regularly invite professional personnel to check the operation of the power storage equipment and the use of batteries to avoid safety hazards.
