Electrical Disconnect

Wholesale Disconnects for Solar Systems

Essentially, safety disconnects allow users to rapidly shut down the system in case of an emergency. For this reason, disconnect switches are required to comply with electrical codes and pass inspection. 

A solar PV system usually has two safety disconnects. The first is the PV disconnect (or array DC disconnect). This kind of disconnect allows the DC current between the modules (source) to be interrupted before reaching the inverter. 

The second disconnect is the AC disconnect. The AC disconnect is used to separate the inverter from the electrical grid. In a solar system, the AC disconnect is typically mounted to the wall between the inverter and utility meter. This kind of disconnect may be a breaker on a service panel, or it may be a standalone switch. Additionally, it is sized based on the output current of the inverter. 

How to Size an AC or DC Disconnect?

Generally speaking, sizing refers to equipment, components, and connectivity (wiring) throughout a solar system as it relates to NEC requirements. The following terms are used to determine component output: 

  • Voltage
  • Circuit load
  • Amps or breaker size
  • Wiring or cables
  • Sizing and Protection of the AC Disconnect

NEC 690.10 stipulates that the circuit conductors between the inverter output and the building or structure disconnecting means shall be sized based on the output rating of the inverter. These conductors shall be protected from overcurrents in accordance with Article 240. The overcurrent protection shall be located at the output of the inverter. 

Important Features to Look For in Disconnect in Bulk?

Disconnects are incredibly useful for solar systems, and so, it is important to get the best possible disconnect for your own solar system. The following are the core features to look for in a disconnect: 

  • Offers bi-directional functionality, which breaks the arc regardless of normal or a reverse current flow
  • Includes all required components to meet NEC 690 requirements, including jumpers and labels
  • Guards against accidental contact with live parts with clear polycarbonate dead fronts
  • Available with modifications that allow customization to meet any application need
  • Sizing of Module Interconnection Conductors and DC Overcurrent Protection

According to NEC 690.80, where a single overcurrent device is used to protect a set of two or more parallel-connected module circuits, the ampacity of each of the module interconnection conductors shall not be less than the sum of the rating of the single fuse plus 125% of the short-circuit current from the other parallel-connected modules.

Manufacturers

In the simplest terms, manufacturing is the process of producing actual goods or items/products through the use of raw materials, human labour, use of machinery, tools and other processes such as chemical formulation. This process usually starts with product designing and raw material selection, turning them into an actual product output. 

Solar Products Manufacturers and Factories

In terms of solar, manufacturing encompasses the fabrication or production of materials across the solar market chain. The most common product being manufactured by solar companies are the solar photovoltaic (PV) panels, which are made with several subcomponents such as solar wafers, cells, glass, back sheets, and frames. Before a solar panel comes into life, it will undergo a lot of processes, from designing, modelling, choosing what raw materials to use and then assembling them all to make the final product.

More Than Just Solar Panels

Aside from the solar panels, solar companies have many other manufactured products that are required to make solar energy systems work smoothly, like solar inverters, batteries, combiner boxes, and racking and tracking structures.

Having a solar manufacturing sector makes a big difference in supplying affordable solar energy in different areas. Aside from maintaining the rising domestic and global demand for cleaner and renewable energy, they also help the economy grow, particularly the solar industry. If you are in search of a reliable solar manufacturing company, checking out our solar outsourcing company, SolarFeeds, would help you get easy access to reliable information, news, data and a list of solar manufacturers that can help you with solar products.
