solar energy Robust DC link capacitors TDK Corporation has extended its portfolio of EPCOS film capacitors for DC link applications with the robust new B3277*M series. The new types are suitable for extreme environmental conditions at 185°F (85°C), 85% relative humidity with a rated voltage applied for 1000 hours. The capacitors of the new series are designed for rated voltages of between 450VDC and 1600VDC and offer capacitance values of between 0.33 μF and 120 μF. The maximum operating temperature of these RoHS-compatible components is 221°F (105°C). Depending on the voltage and capacitance, the lead spacings are 27.5mm, 37.5mm and 52.5mm, and a 2-pin or 4-pin version is available for each lead spacing. The service life of the self-healing capacitors is 50,000 hours at the rated voltage and an operating temperature of 185°F (85°C). Typical applications include DC links of converters for photovoltaic plants, as well as frequency converters and power supplies for industrial applications. The series is qualified in accordance with AEC-Q200. TDK Corporation /// www.tdk-electronics.tdk.com Turnkey solar resource assessment solution A new and complete solar resource assessment (SRA) solution has been introduced to the US market via a collaboration between ArcVera Renewables, NRG Systems (NRG), and Harness Energy. This end-to-end offering will provide solar project developers with the design, manufacture, shipping, installation, and operation of their solar measurement systems, including the delivery of independent campaign monitoring and finance- grade resource assessment reports. The ArcVera-NRG-Harness collaboration promotes independence in the three main areas of a solar energy assessment: equipment procurement, installation and maintenance, and data analysis. NRG supplies its highly integrated and standardized solar met stations for a repeatable measurement result; Harness Energy provides the installation and ongoing operations, including the maintenance of mission critical pyranometers; and ArcVera Renewables provides independent technical advisory services, ensuring the met stations are generating the quality data required to deliver accurate, bankable assessment reports. Each provider focuses on delivering excellence in their respective domains and when these offerings are combined, there are considerable benefits to customers.

Recessed into the frame of the solar module, the integrated micro-inverter, designed by LG Electronics, allows for the NeON R ACe to be a solution for both installers and homeowners, saving time, space, and money. This integrated design eliminates the need for a separate inverter, thereby reducing clutter from outside walls and rooms within the home. Requiring only two types of accessories, it provides straightforward logistics and reduces the time needed for preparation and installation. The new LG NeON R ACe provides a premium, clean, and sleek aesthetic for residential and light commercial applications. The elimination of electrodes from the front of the module and relocation to the back creates a seamless array of panels. LG’s 25-year limited warranty for products, parts, and performance applies to the NeON R ACe and covers both the panel and the inverter, giving homeowners and installers a great degree of investment security from a brand they can trust. For added convenience, the LG NeON R ACe provides a user-friendly app- based monitoring service system called EnerVu. Through this app, installers and homeowners can monitor the system's energy flow from any location and, if a technical issue arises, alert LG customer service to help address it remotely.

The SMT77 comes preinstalled with device configuration software and device library, so it is ready to go, right out of the box. The device enables plant asset management in Class 1 Div 1 hazardous areas. The Field Xpert device library has more than 2700 pre-installed device and communication drivers, allowing it to work with many different instruments from a wide variety of vendors. It can connect to field instrumentation devices directly via a USB or Bluetooth wireless modem, or via a gateway, remote I/O, or multiplexer to a bus system. The tablet PC has Windows 10 Pro software installed. It comes with an 10.1" LCD Multitouch HD display, 2x bonded Gorilla Glass, a 5MP auto focus camera, a 2MP front facing camera, and up to 128GB storage. Communication ports and supported networks include USB, Ethernet, HDMI, Wi-Fi, and Bluetooth, with 4G LTE and GPS available as an option. The battery runtime is five hours. The SMT77 comes in a general purpose configuration as well hazardous area configuration for Class 1, Div 1 and meets all the legal requirements of the relevant EU directives and is IP65 compliant.
