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.

Distributors

Solar Products Distributors

Distributors are those companies working as big warehouses that served as the middlemen between the consumer/customer and the manufacturer. Typically, in distribution, a company is handling the sourcing, stocking and logistics but nowadays they are also helping manufacturers in product designing and solving other business conflicts. 

Aside from other industries, distributors also play a vital role in the solar industry. Solar distributors become long-term partners of solar manufacturing companies and even solar contractors. They are not only serving as warehouse facilities but partners that also provide strategic solutions to help solar companies achieve their desired outcomes. Solar distributors assist solar manufacturing companies by storing. handling and shipping their solar products to their buyers. On the other hand, they help solar contractor companies in outsourcing high-quality solar products. 

These solar distributors are the ones who deal with homeowners who want to go solar, businesses that work with the solar industry and solar installers who offer solar system services to both residential and commercial customers. But on top of that, the solar distributor’s main role is to maintain its commitment to outsourcing and handling high-quality products and delivering them to customers at a good value. 

Up to these days, many solar distributors have been operating and helping many solar companies in distributing their products. So, if you are looking for the most trusted and reliable solar distributor, you can easily find one by checking out solar outsourcing companies that provide easy access to reliable information, news, data and a list of solar suppliers and distributors near you.

Kazakhstan

Kazakhstan: A review of solar market performance

Five years ago, the Republic of Kazakhstan embarked on an ambitious transition towards renewable energy particularly, solar and wind. The goal was to ensure that 50 % of the nation’s energy generation stems from renewables. Nearly a decade down the line, Kazakhstan has recorded outstanding success. Some solar industry experts argue that the country is currently central Asia’s solar superpower.

According to the IREA, Kazakhstan’s installed solar capacity stands at approximately 500 Megawatts. This is a substantial accomplishment considering that the country’s solar capacity was pretty negligible five years ago. What are some of the reasons behind this unprecedented success?

Well, the Kazakhstani government has taken various actions aimed at attracting investments to its solar market. Some of these actions include the implementation of feed-in tariffs and conducting renewable auctions for upcoming projects. It has also aligned with several prominent financial institutions to finance various projects. It is also worth noting that the Eurasian Development Bank (EDB) plans to invest $600 million in Kazakhstan’s solar market. This means that the market will continue to grow and generate opportunities for solar installers and solar professionals.

Does Kazakhstan have the capacity to supply solar equipment?

Kazakhstan boasts of several solar equipment suppliers. Consequently, it is accurate to say that it can supply different categories of solar equipment. Still, you can easily import any locally unavailable solar equipment. There are several ports in Kazakhstan through which you can receive your solar equipment. Also, there are several dependable logistics companies that can help transport the solar equipment to the project site.
