About The photovoltaic panel output line can be connected to a circuit breaker

The most common is a "LOAD SIDE" connection, made AFTER the main breaker. The alternative is a "LINE OR SUPPLY-SIDE" connection made BEFORE the main breaker.

The National Electric Code allows for a few different ways to interconnect PV systems to utility systems. In two editions of Code Corner, Ryan Mayfield with Mayfield Renewables, explains busbar, load side interconnections in 705.12 (B) (3) (1) and (2), and then supply side connections in 705.11 (C) and (D). Mayfield Renewables Code Corner .

How can you connect your solar PV system to a standard circuit breaker box (utility service panel). We will walk through a step-by-step process of making a load side connection of a.

A backfeed breaker can be used to connect a solar PV system to the load-side of a service. There are several different ways this can be done per the NEC but the most common method for solar residential installs is by connecting it to the end of a busbar using the 120% rule (705.12(D)(2)(3)(B)).

Circuit breaker connection: The AC wires from the inverter connect to the electrical panel through a circuit breaker. This is the most common type of connection with residential systems and is always allowed by utilities. It is also used with commercial applications whenever the main panel can accommodate the PV backfeed current.

6 FAQs about [The photovoltaic panel output line can be connected to a circuit breaker]

Can a backfeed breaker connect a solar PV system?

What is a PV backfeed circuit breaker?

This is the most common type of connection with residential systems and is always allowed by utilities. It is also used with commercial applications whenever the main panel can accommodate the PV backfeed current. The overcurrent protection devices are the main circuit breaker and the electrical panel's PV back feed circuit breaker.

How do inverters connect to electrical panels?

Can a solar circuit breaker be a load-side connection?

Both rules must be satisfied to meet Code when using a load-side connection. Known as the 120% rule, the solar circuit breaker can be no more than 20% of the main electrical panel rating. The electrical panel rating Amps (A), or Busbar rating, is the manufacturer rating typically found on a label.

Where should a PV breaker be located?

Example on that last point of being able to put the breaker anywhere you want, with this PV breaker located actually at the top of the busbar: In this case, 160 amps x 125 = is 200 amps. “So, it’s not the rating of the breaker for the PV system, it’s a 125 percent times the continuous output current.

Which side of a PV system meets the utility metering requirements?

b) The AC side of the PV system (between the inverter and the utility meter) meets the utility's safety requirements (labeling, location of equipment, connection to electric panel). c) The power and energy generated meet net metering program requirements.
