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.

Egypt

Solar Market Outlook in Egypt

The future is bright for the solar energy sector in Egypt. Until the government took serious steps to promote and expand the renewable energy market in the country, the government budget on electricity subsidies exceeded that which were allotted for healthcare, education, and social welfare. In 2018, the government collaborated with the World Bank to reform the country’s power sector and to invite private investments into the country. 

This helped to facilitate the installation of 6 million solar panels in what is now known as the Benban Solar Park. Installed in the Egyptian desert, it spans a total land area of 36 square kilometers. It spans more than 32 contiguous solar projects in one.

This solar park is set to become known as the world’s largest solar installation with the capability of producing over 2,000 MW of power. If that pushes through, it is capable of lighting thousands of homes and businesses in Egypt.

Solar Energy Equipment Supply Capacity in Egypt

As one of the top proponents of solar energy production in Africa, Egypt leads the way in terms of solar equipment distribution. However, the majority of the solar equipment supplies in the country are from foreign and online suppliers. 

Top Major Seaports & Logistics in Egypt

There are plenty of ports in Egypt that will serve as gateway for the transport of solar power equipment and supplies such as the following:

• Port of Abu Quir,
• Port of Al-Tour,
• Port of Alexandria,
• Port of Tig Marina,
• Ain Sukhna Terminal,
• Port of Adabiya,
• Port of Berenice, 
• Port of Damietta.
