Prepare in advance
To connect the solar panels to the grid, you need to prepare other equipment including inverters, metering devices, protection devices, etc. You will then need to obtain a grid access license from the local authority. Then you need to obtain a grid access license from the local authorities, usually the manufacturer of the installed solar panels has this kind of grid access license.
Installation steps
(1) Installation of solar panels
You need to choose the right individual solar panel power according to your demand for electricity and then lay a reasonable number of solar panels, and then choose a suitable place for the installation of solar panels and batteries.
(2) Organize the wiring.
According to the power of solar panels and the type of inverter to determine the series or parallel connection, and arrange to connect the various solar panels of the line laying. When choosing fiber optic cable, it should be combined with the power generation, not hot and easy to cause accidents.
(3) Connect the inverter.
The inverter is the core of the entire line, when choosing the location of the inverter should be convenient for maintenance and view, while the installation location should be relatively safe. Solar panels produce DC power, and the inverter converts this DC power into AC power.
(4) Connect the meter.
The meter is convenient for calculating the converted real-time power and viewing the total power generation of the solar panels, which is conducive to the comprehensive testing of the power generation capacity of the solar panels.
(5) Connect the circuit breaker.
The connection of the circuit breaker is very necessary to prevent electrical short circuits caused by various reasons, and the resistance wire can cut off the circuit in a very short time, avoiding fires caused by electrical short circuits.
(6) Connect the grounding wire.
In addition to the circuit breaker, to ensure that the solar system is connected to the ground, the occurrence of short-circuit ground can quickly lead the electric body into the ground, to a certain extent, to prevent the occurrence of electric shock.
(7) Connected to the grid.
According to the user’s power generation scale to choose the connection method, the grid needs to be connected to the staff to develop a rigorous planning and repeated debugging, in order to prevent the occurrence of accidents and the user’s interests are maximized to ensure.
The method of connecting solar panels to the grid
(1) Load-side connection. This connection is simple and inexpensive, load-side connection is through the load side of the photovoltaic power generation system and electric service providers connected to each other, but this connection is not high power suitable for lower power photovoltaic system.
(2) Line/power side connection. Line-side connection is the PV system in the main service panel and meter increased junction box, the connection is more complex, allowing higher PV system connection.
Solar panel loading
To cope with special situations we generally choose to load suitable solar cells, a decision that proves necessary in case of power outages and low power.
Grid connection What do I need to know?
(1) Grid-connected customers can choose to earn a fee for the excess power that is delivered to the grid after it has been used for household purposes.
(2) Do not modify and add solar panels privately, solar panels into the grid is strictly regulated by staff, private modification will lead to accidents
(3) When the photovoltaic power generation system appeared abnormal immediately contact the staff, not their own direct maintenance.
Summarize
The solar panels connected to the grid can provide users with the convenience of electricity to save the residents of electricity can also bring certain economic benefits, the grid needs to be carefully connected to do a good job of the basic protection of electricity
