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.

Wholesalers

Solar Products Wholesalers 

Wholesaling refers to buying some products or goods directly from its manufacturer usually at a discount and then reselling it to the retailers for a comparatively higher cost than the original. Basically, wholesalers handle products and package them in small quantities and then sell them to retail customers, either for commercial or personal use. 

Many industries have wholesalers, and that will not skip the solar industries. Nowadays, many solar wholesale stores/firms are operating across the globe, making it much easier for retailers to go solar. Sometimes retailers find it hard to reach direct manufacturers of solar products because some companies do not have their solar stores/shops in public, with that they are not also offering solar products per piece. Through wholesale solar stores/shops, these individuals can easily buy the solar products that they need to replace or maintain their solar systems. 

If you are in need of solar product suppliers for an individual purpose, you may visit some solar outsourcing marketplace to get an updated list of solar wholesalers near your location. There are many solar platforms that provide enough information and data about the solar industry in your region, including all the reliable solar wholesalers in town.

El-Salvador

Solar Market Outlook in El Salvador

Despite being the smallest country in Central America, El Salvador is one of the strongest proponents of renewable energy production in the region. This is part of the government’s commitment to reduce emissions and to increase energy efficiency while utilizing the country’s tropical climate. The hot and humid weather, along with the high rate of sunshine per year, makes it the best location to utilize solar energy and other renewable energy sources. The average daily solar radiation in El Salvador is measured at 5 kWh/m2.

The National Energy Policy mandate in El Salvador has helped to boost its renewable energy production. Currently, it accounts for over 60% of the country’s energy production, although solar sources only contribute to 4% of that.

This is set to change in the coming years, though, as El Salvador is focused on increasing its solar PV installation capacity. They have helped increase PV generation capacity through auctions since 2014. Still, it cannot be denied that the solar market in El Salvador is still in the nascent stage and the government is looking at investment incentives and other policies to encourage development of solar PV. 

Solar Energy Equipment Supply Capacity in El Salvador

There is currently a limited amount of domestic investments on solar generation plants in El Salvador. However, there are plenty of global suppliers and distributors that can be tapped at the moment for those looking to make solar installations.

Major Seaports & Logistics in El Salvador

The Port of Acajutla is the primary seaport in El Salvador that facilitates the handling and logistics of solar equipment and other goods (both import and export). This makes it convenient for anyone looking to order from top suppliers for solar installations. 

In addition to this, there are other smaller ports like Port of La Union and Port of La Libertad
