PV inverter is complemented with cloud-based monitoring apps

Tue, Dec 10, 2019

At EnerGaia 2019 in Montpellier, France, Delta Electronics will highlight the M70A solar PV inverter and PV monitoring apps.

The M70A solar PV inverter offers 77kVA maximum AC apparent power for ground-mounted and commercial solar rooftop systems.

The company has also developed MyDeltaSolar Cloud and PV monitoring apps for remote setup, monitoring, and control of solar photovoltaic systems.

The M70A is a three-phase string inverter with 77kVA maximum AC apparent power for ground-mounted and commercial solar rooftop systems. The design is compact and lightweight, making it easy to transport and install. There are six MPP trackers with three pairs of connectors each to allow system planners flexibility in arranging module strings and maximising yields. Module rows for ground-mounted systems require only minimal spacing as a result. Smart allocation of the MPP trackers can compensate potential shadowing, added Delta Electronics.

Even complex rooftop systems that have multiple sections with different alignments are easy to implement with the M70A, continued the company. If the system uses two strings per DC input, it does not require external string breakers.

Peak efficiency for the M70A is 98.8 per cent and it has a broad input voltage range from 200 to 1,100V DC. It can accommodate up to 18 strings via Amphenol connectors and string monitoring includes measurement of the I-V curve data at each individual string.

There are Type 2 surge protection devices pre-installed on the input and output sides and the inverter is supplied in a robust aluminum housing with IP65 protection.

The cloud monitoring service with free app for iOS and Android, MyDeltaSolar Cloud works with all Delta inverters and allows operators and installers to quickly set up and manage multiple systems and inverters. The system is available free of charge for five years with the purchase of a Delta solar inverter.

Users can monitor the performance of their Delta inverters in the MyDeltaSolar Cloud including current and voltage data. They can also see daily, monthly, and annual PV yields. No cabling is required to connect a wireless-enabled Delta inverter to the new Delta DC1 data collector. Delta’s M6A, M8A, and M10A inverters all ship with wireless communications pre-installed and Wi-Fi is an optional feature for the M70A.

Alternatively, installers can connect to the MyDeltaSolar Cloud via the inverter´s RS485 interface. Delta hosts the cloud software on its own secure servers to guarantee maximum data security and protection against external threats.

Anritsu launches PCIe option for Gen5 testing

Tue, Dec 10, 2019

To support the Gen5 Base Specification stressed receiver test, Anritsu has released a PCI Express )PCIe) test solution which uses its MP1900A signal quality Analyzer-R series, which offers automation software for base specification calibration and bit error rate (BER) measurement software supporting the SKP filter. Customers can use it to configure a measurement environment for early-stage development of Gen5 IP and devices, to accelerate the introduction of PCI Express 5.0.

The MP1900A offers all the pattern generation, error detection, jitter generation and noise generation functions required for PCI Express tests in a single unit. Gen1 to Gen5 transmission speeds can be supported by upgrading the equipment via software, for cost-efficient PCI Express testing.

Technologies, such as IoT and artificial intelligence (AI), are expected to see rapid growth as commercial rollout of 5G services make high speed transmission of the required large volumes of data feasible.

Data centers supporting these technologies require increasingly faster processing and greater data handling capacity. This means that data-centre transmission equipment, servers, and storage devices need internal interfaces able to support faster, higher-capacity data transmissions. Base Specification 5.0 of the next PCIe Gen5 standard has been completed and increases data transfer speeds to 32GTerabytes per second. It is evident that equipment needs to be developed to support this standard, said Anritsu.

This release allows Anritsu to support Gen5 Rx tests for IP and inspection of devices in the early stages of standardisation and development, offering all-in-one Gen1 to Gen5 measurement support. Expansion of measurement functions to meet new emerging standards and trends will also help customers design inspection times.

The signal quality Analyzer-R MP1900A series is a multi-channel BER tester meeting the design and verification requirements for high-speed bus interfaces, such as PCI Express 4.0/5.0, USB3.2/4 and Thunderbolt, as well as next-generation network interfaces such as 200G/400G/800G Ethernet. The MP1900A series incorporates a built-in pulse pattern generator for generating high-quality waveforms with what are claimed to be best-of-class levels (e.g. intrinsic jitter of 115 fs rms) and a high-input-sensitivity error detector, as well as a high-accuracy jitter generation source (SJ, RJ, SSC, BUJ), CM-I/DM-I/white noise source, link training function and support for LTSSM analysis.

These features make it suitable for compliance tests, margin tests and troubleshooting. The signal quality Analyzer-R MP1900A series also supports PAM4 evaluation of PAM4 devices, including optical modules and NICs, used by 200G/400G/800G Ethernet in data centres.

Prototyping board simplifies IoT end point development

Fri, Dec 06, 2019

For rapid product development, Renesas has introduced the RL78/G14 Fast Prototyping Board. This inexpensive, function-rich board is designed to enable rapid product development for IoT endpoint equipment. Quicker development prototyping and lower costs allows users to respond to rapid changes in technology and market needs, and reduces the time to market window for new products, says the company. Renesas also introduced the RL78/G1D BLE Module Expansion Board, which users can combine with the new prototyping board to easily add Bluetooth Low Energy wireless communication functions.

The new prototyping board is based on the RL78/G14 microcontroller, which provides the richest set of functions in the low-power RL78 family. It is suitable for motor control in portable equipment and IoT sensors as well as a wide range of IoT endpoint equipment, such as home appliances, industrial equipment, building automation and healthcare equipment.

Previously, the RL78/G14 starter kit and target boards required an external emulator. There were additional costs associated with high performance versions. The RL78/G14 Fast Prototyping Board is priced to be affordable, says Renesas and has an on-board emulator circuit with the same functions as the E2 Emulator (E2 Lite), so the user does not have to purchase additional debugging tools. The board provides access to all of the RL78/G14 signal pins and includes Arduino and Pmod interfaces for easy functional expansion.

By combining a Semtech SX1261 or SX1262 LoRa transceiver with this prototyping board, it is possible to prototype for IoT sensor devices using wireless communication based on LoRa with extended period battery drive, advised Renesas. The company also provides circuit diagrams, parts lists and user manuals necessary to jump-start development, in addition to sample code and application notes related to these products.

The RL78/G14 is the most powerful microcontroller in the RL78 family, achieving a numerical processing performance of 51.2DMIPS at 32MHz. It includes up to 512kbyte of flash memory and up to 48kbyte of RAM. It provides functions such as timers and 8-bit DACs. In particular, it achieves the industry’s lowest levels of current drain, 66 microA/MHZ, when the CPU is operating and 240nA in standby mode. This microcontroller is optimal for battery-powered portable equipment and IoT sensor terminals, as well as a wide range of IoT endpoint equipment.

Both boards are available now.
