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.

OEM

Custom Made Solar Products OEM

OEM stands for Original Equipment Manufacturer which is commonly referred to as a company that manufactures and offers parts and accessories of items that are used as components of a product from another company. To sum it up, OEM commonly manufactures specific items on behalf of brands. Though OEM typically operates in the computer and technology industries, it also works in the solar industry.

Factories for White Label Solar Products

In the case of the solar industry, most solar companies work with solar OEMs to build and design their own solar products such as solar panels, cells, modules, etc. OEM becomes their outsourcing partner that helps them in assembling and reproducing their solar products.

Nowadays, a huge number of solar companies, particularly those large solar manufacturing companies, are partnering with outstanding solar OEMs to deliver the best quality solar products to their solar customers. Mainly, the reason is, these solar OEMs help solar manufacturers cut down their production costs since they no longer have to operate their own factories, purchase needed materials and hire labour to produce their solar products.

As a solar manufacturing company, the first thing you need to consider is to find the most reliable solar OEM in the market. One of the biggest perks of the internet these days is you can now easily find these OEMs even in the comfort of your home. With the help of a solar outsourcing marketplace such as SolarFeeds.com, you can easily find the most reliable and right OEM partner for your solar company. Solar outsourcing marketplace helps solar industry professionals gather accurate and timely information about solar including the list of most trusted Solar Original Equipment Manufacturers.

Portugal

An Analysis of Portugal’s budding solar market

During the forecast period 2020-2025, it is expected that the solar market in Portugal will grow at an annual rate of more than 8 %. Rising energy demand, efforts to reduce our reliance on fossil fuels, and declining costs of solar PV and associated systems are among the primary drivers of the market.

The solar energy market is also driven by factors such as rising demand for renewable energy, rising investments in solar farms, and government policies. In the coming years, the market for wind energy will likely be restrained by the increasing adoption of an alternate clean power source like the wind.

The Portugal solar market is expected to grow at a significant rate due to ongoing efforts by the Portuguese Government and their future policies.

Portugal’s solar equipment production and supply capacity

The Portuguese market is home to several suppliers and manufacturers of solar equipment. Solarfeeds is the best place to buy solar equipment.
