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:
- 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.

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.
Solar Market Outlook in Turkey
The outlook is good for Turkey’s overall renewable energy industry, with the exception of hydropower. In 2020, the country’s renewable energy production reached 19.07 GW. The country is projecting a total energy production from solar energy and other renewable sources to 49.31% by 2030. This results in a compound annual growth rate of 10%, which is very promising for the country’s solar energy efforts.
The solar energy sector is one of the best performing among its renewable energy market. In 2018, it has already achieved its 2023 target of 5 GW solar PV capacity. They are hoping to increase that to 15 GW by 2027. Given the annual growth rate of the solar energy sector, they can easily meet that target, as long as they can sustain growth.
The Renewable Energy Law in Turkey has been an effective tool to facilitate the government’s efforts to achieve its solar energy target. The government also believes that the privatization of the power distribution in the country has contributed to boosting the level of competition and subsequently growing the solar capacity in the country.
Solar Energy Equipment Supply Capacity in Turkey
There is a good mix of local and foreign suppliers and distributors of solar power equipment in Turkey. This makes it easy to promote solar PV capacity in the country, whether for residential and commercial installations.
Top Major Seaports & Logistics in Turkey
Turkey’s logistics and trade activity is facilitated through one of its many commercial seaports. The following are some of the busiest ports that you can take advantage of to transport solar equipment and supplies:
- Port of Haydarpasa,
- Port of Mersin,
- Port of Eregli,
- Port of Izmir,
- Port of Gemlik,
- Port of Ambarli.
