Different types of inverter connected to the meter method

2024-12-20

The connection between an inverter and a utility meter depends on the type of system and the specific application, but here’s an overview of the most common setups:

Grid-Tied Solar Systems

Grid-connected inverter refers to the direct current emitted by solar panels (or other solar power generation equipment), converted by the inverter into mains alternating current, and connected with the mains power grid, through the grid to provide power to users, while the excess power is reversely transmitted to the grid, through compensation to obtain benefits.

Wiring method

The AC output of the inverter is usually connected to the mains, so it can be directly connected to the meter, without the need for additional conversion equipment, the specific connection method is as follows:

Step 1: Connect the AC output of the inverter to the "inlet" position of the meter.

Step 2: Connect the "exit" position of the meter to the power interface of the mains grid via a wire.

Precautions

Before connecting the meter, ensure that the inverter is working properly, so that the meter reading can be accurately obtained.

Off-Grid Systems

Off-grid inverter means that the direct current emitted by the solar panel is stored in the battery, converted into alternating current through the inverter, and provided to the user, and does not need to be connected to the mains alternating current grid.

Wiring method

Since the off-grid inverter does not need to be connected to the mains AC network, it is necessary to set up an independent circuit for connecting the meter, the specific connection method is as follows:

Step 1: Connect the AC output outlet of the off-grid inverter to the battery.

Step 2: Connect the battery's DC output to an ammeter.

Step 3: Connect the AC outlet of the ammeter to the entry position of the meter

Step 4: Connect the outlet of the meter to the outlet of the ammeter by wire.

Precautions

An ammeter needs to be added to the off-grid inverter to convert direct current to alternating current and accurately measure the power data.

Hybrid Systems

Hybrid systems with batteries follow a similar connection path but may include additional equipment:

Step 1: The inverter manages power flow between solar panels, batteries, loads, and the grid.

Step 2: AC power flows from the inverter to the electrical panel, which connects to the meter.

Additional Component:

A battery management system (BMS) may control when to send or store power, potentially influencing the meter's reading.

Wiring Considerations

Compliance: Wiring must comply with local electrical codes and standards.

Safety: Connections should only be made by a licensed electrician to ensure safety and proper operation.
