SolarEdge products ready to meet both NEC 2017 and Rule 21 Phase 3

 

SolarEdge

SolarEdge Technologies is ready for the implementation of both NEC 2017’s revision to the PV Rapid Shutdown System (PVRSS) requirements for 2019 and is prepared for the roll out of Phase 3 of Rule 21. The company offers solutions that comply with these regulations.

“By preparing our product lineup in advance of the soon-to-be implemented standards, we ensure that our installers can continue to meet installation demand without any delays or disruptions,” stated Peter Mathews, General Manager North America.

SolarEdge will continue to support increased solar proliferation with compliance to Rule 21 Phase 3. With the implementation in February 2019, some Rule 21 Phase 3 requirements will become mandatory. Accordingly, SolarEdge will provide an expanded feature set for smart inverters to support a more interactive and stable grid. Features like data monitoring, remote connection/disconnection, and max power controls will start to become the new industry standard.

All SolarEdge inverters sold in California will be certified for IEEE 2030.5, while already shipped SolarEdge inverters can be updated for compliance. To support the increasing need for cloud connectivity, SolarEdge will also offer a selection of flexible cellular data plans for all its inverters.

The newest provision of NEC 2017 (690.12), which reduces the shock hazard in PV arrays for enhanced firefighter safety, is set to go into effect in January 2019. Requiring no additional rooftop hardware, third-party vendor solutions, or changes to installation, SolarEdge offers residential and commercial power optimizers that meet the PV Rapid Shutdown System (PVRSS) 2019 requirements. SolarEdge’s fully integrated solution provides advanced safety compliance by controlling the system at the module level. Upon rapid shutdown initiation, SolarEdge’s power optimizers are designed to rapidly reduce the voltage inside and outside of the array.

Russelectric debuts new energy controller for distributed generation systems

russelectric distributed energy controller

Russelectric, a manufacturer of automatic transfer switches and power control systems and solutions, released a new Russelectric Distributed Energy Controller (RDEC). RDEC is a fully integrated controller for complex, mission critical distributed energy systems, ranging from back-up generation and demand management to fully functional microgrids. At the core of each RDEC is the ability of Russelectric’s transfer switches, switchgear, and power controller to provide seamless physical, data, and control integration of a facility’s onsite demand and generation assets.

RDEC has a number of features that improve business continuity and power quality. Facility integrated solar capabilities, priority-based load shedding, and permitted emissions optimization all enable RDEC to provide least cost, least emission business continuity strategies for both short and long duration outages. In addition, RDEC improves facility power quality, benefiting internal equipment and reducing utility power quality charges via dynamic islanding capabilities, fast and reliable decoupling, automatic black start of backup generators, seamless grid resynchronization, and more.

In addition to improving business continuity and power quality, RDEC reduces energy costs and green-house gas emissions. Features such as demand reduction and time of use asset optimization all allow RDEC to optimize a facility’s controllable demands, onsite storage and power generation to reduce energy costs and cost volatility. Furthermore, RDEC fully integrates onsite renewable generation resources into a facility’s distributed energy system, reducing a facility’s GHGs, making it easier to reach sustainability goals.

The RDEC base system includes Russelectric automatic transfer switches, switchgear, and a power control cabinet. Depending on power control needs, an optional SCADA and Electric Power Management System can be added. Russelectric can also provide storage systems or work with a user’s selected storage supplier.

ABB launches a few new eBOS components for 1,500 volt PV systems

ABB inverters

The shift to higher voltages is helping reduce the cost of utility-scale photovoltaic systems. Higher-voltage systems make installations more energy efficient, require fewer components and less wiring, and are less labor intensive to build. Most new solar plants have voltages of 1500V on the DC side and many are moving towards 800V on the AC side.

ABB is adding a new molded case circuit breaker (MCCB) for higher-voltage solar power plants to its Tmax PV range and launching the solar industry’s first fully optimized two-pole DC (OTDC) switch-disconnector for 1500-volt utility-scale plants covering 315-630A IEC and 250-600A UL current range.

Disconnector

The new design offers both a size reduction and an increase in efficiency and performance to help manufacturers of PV combiner boxes, inverters, and energy storage systems adapt to the industry’s rapid adoption of 1500V DC solutions.

The two-pole 1500V DC concept helps manufacturers improve system efficiency, reducing switch losses by up to 35 percent. Measuring just 150mm wide and 122mm high across the current range, the OTDC range of 1500V DC switches is also up to 30 percent smaller than conventional solutions. The compact size of the new OTDC range makes it possible for manufacturers to reduce the size of combiner boxes and inverters.

ABB’s unique design makes it possible to operate up to two 1500V DC strings with just one switch. In addition to the standard connections, the OTDC’s modular design also makes it possible for ABB to fulfil the non-standard requests that come from the quickly changing solar market.

Molded case breaker

The breaker, designed to protect combiners, switchgear and inverters up to 1500V DC, is the latest addition to ABB’s complete range of protection solutions for utility-scale solar plants.

For 1500V DC installations with rated current up to 1200A UL and 1600A IEC, ABB’s product range now includes MCCBs and switch-disconnectors. The SACE Tmax PV range makes installation faster and reduces wiring costs for more advanced solar plants, helping utilities and engineers save time. The SACE Tmax PV offers design engineers, panel builders and inverter manufacturers a single–brand solution for photovoltaic systems installed anywhere in the world. All integrate readily with the electrical and mechanical accessories developed for the SACE Tmax T MCCB range.

For systems using string inverters, the SACE Tmax PV range now offers circuit breakers for up to 800V AC, the industry’s first to be type approved to UL 489 specifications and compliant with IEC 60947-2 Standard. ABB’s compact circuit breakers can break short circuit currents up to 32kA.

“We believe 800V AC will be a significant trend in large-scale solar plants,” said Marco Carminati, Global Product Specialist for ABB’s low-voltage breakers. “The response from partners indicates that it will be central to many developments in this field. We are now planning further innovations to support the shift to 800V so that solar plants have everything they need to optimize their power production.”

Seaward improves PV testing range, uses new I-V curve algorithm

seaward solar i-v curver tracer

Solar test equipment manufacturer Seaward Group has relaunched the latest in its popular range of solar PV test equipment with new features to keep it at the forefront of the industry.

The new PV200/210 Complete Kit, which builds on the success of the original PV200 and 210 devices, has new functionality to boost performance and precision. Innovative new functions include a brand new I-V curve algorithm designed to produce higher resolution results.

Users will also find new messages that indicate if there has been a problem with the test – limiting occurrences of invalid tests and saving time on site. Even better, combiner box text leads and a mounting bracket are now included with every kit as standard – previously users had to purchase these separately.

Michael Middlemast, category manager at Seaward, said: “We had a fantastic response to the original PV200 and 210 devices – which provide an intuitive and cost-effective way to measure the I-V curve of PV modules and strings. The improved level of accuracy makes the devices even more efficient to use –limiting downtime and increasing energy production.”

Seaward also announced exciting updates to the PV200/210’s software, SolarCert Elements V2. The latest version of the software now simply called SolarCert, enhances the I-V curve reporting function, allowing users to quickly and easily generate a report for thousands of strings.
