How does a utility meter connect to a solar panel?
There is an ALTERNATIVE UTILITY CONNECTION called a “Supply or Line Side" connection. This connection is made BEFORE the main breaker. A junction box is added between the utility meter and the main service panel. Then the wires from the utility meter, the main breaker panel, and the PV solar are connected in the junction box.
How do you connect a solar inverter to a utility meter?
A junction box is added between the utility meter and the main service panel. Then the wires from the utility meter, the main breaker panel, and the PV solar are connected in the junction box. An adequately sized PV service disconnect box must be used prior to making the connection between the junction box and the solar inverter.
How do you use a voltmeter on a solar panel?
Measure the voltage between the +ve and -ve terminals by connecting the negative contact from the voltmeter to the negative on the panel and the positive contact on the voltmeter to the positive on the panel. Angle the solar panel towards the sun. Ensure that the multimeter is set at 10A, at least to start with.
How do I connect solar panels to the grid?
To connect solar panels to the grid, you need to install a bi-directional meter on your home. This allows energy produced by your solar panels to be fed into the grid when you’re not using it, and for you to draw energy back from the grid when you need it.
Why should a solar PV system be connected to the grid?
For financial benefit. Connecting your solar PV system to the grid allows you to take advantage of the FIT, which gives you a fixed amount of money for each kWh of electricity you generate. On top of these payments for energy generation, you also receive a sum of money for feeding any surplus energy into the grid.
