A Hoymiles has launched its latest RSD (rapid shutdown) solution for rooftop PV systems. Comprising HRSD-1C, HRSD-2C and Transmitters, the product is now available in North America, Southeast Asia and the Greater China region.
“Our module-level shutdown devices are designed to be connected with one or two panels. When installed and receiving a 'permission to operate' signal from the Hoymiles Transmitter, the HRSD initiates proper operation of the system,” the company said in a statement.
“In the event of an emergency, the plant will enter rapid shutdown mode by simply disconnecting the transmitter's AC power or using an external initiator, bringing the PV system to safety in 30 seconds,” they explained.
The HRSD supports an input operating voltage range of 8V to 80V and is compatible with almost all PV modules. Furthermore, it operates within -40 to +85℃ and has a 25-year warranty. “Our HRSD product line will soon see new members with module-level monitoring function,” they emphasized.
Hoymiles microinverter is listed on INMETRO
O microinverter Hoymiles HM-1800T-S was listed in INMETRO (National Institute of Metrology, Quality and Technology). “This ultra-economical model is expected to become one of the main products we offer in Brazil and Latin America in general”, highlighted the company in a statement.
According to the company, it comes with an innovative 4-input design that maximizes efficiency and reduces costs, is ideal for 182mm and 210mm photovoltaic modules and has an MPPT efficiency of 99,8%. The equipment also has a Sub-1G wireless solution, which allows stable communication under complex environmental conditions, and is suitable for commercial and industrial settings.
An answer
My dear thinkers... quick shutdown in 30 seconds? Any turtle is faster. Any circuit breaker will do for quick manual shutdown. That's talking about manual speed. Now, when it comes to shutdown at the module level, the question remains: if the module is on fire, what will it shut down? If you think about protection against electric shock, the correct device is not the MANUAL quick shutdown. Caracas... since when does the fire department understand electrical energy to regulate electrical systems? They're trying to eliminate ABNT in every way. It's better for manufacturers to manipulate an agency that doesn't understand anything about the subject.
