Sunrun chooses SMA America as a key supplier of residential PV solutions.
In part two of our three-part series, we covered the support features that our Sunny Tripower three-phase inverters and Sunny Boy single-phase inverters have that implement proactive responses to grid requirements. Frequency Ride-Through and Voltage Ride-Through in particular are crucial for the definition of operation ranges of the inverters and the expected response for different levels of anomaly in the voltage or natural frequency of the grid.
Penetration of distributed energy resources (DER) such as PV has increased rapidly over the past few years resulting in concerns about grid reliability.
California’s Investor owned utilities (IOUs), through California Electric Rule 21, are now requiring that inverters come equipped with several new safety features and advanced grid functionalities. The new rule establishes specific requirements for generation facilities to be connected to a utility’s distribution system. This regulation has been in effect since September 2017, and although it only applies to California, other states across the nation are expected to adopt measures like this in the future.
Fortunately, smart inverters like the Sunny Boy-US contribute to the stability of the grid and use unique autonomous functions that allow you to fully comply with UL 1741 SA standards.
Watch this Tech Tip to learn how to utilize these grounbreaking functionalities! You will see how easy it is to use a single file package to configure the Sunny Boy to be in full compliance of CA Rule 21’s phase 1 requirements.
SMA is the top O&M supplier in North America in the inverter-based provider category.
If you didn’t cash in on your $50 rebate for Power+ installations, you still have time.
The diesel generators have fallen silent. No longer is the idyllic island of St. Eustatius tarnished by their drone and black diesel soot. And gone, too, is the need to buy expensive diesel fuel. In November 2017, this Caribbean island – a “special municipality” of the Netherlands – became that little bit more special thanks to the launch of a diesel-free daytime electricity supply.
