Single unit microinverter HERF-300 / HERF-400 / HERF-500 is the perfect selection for PV system with an uneven number of panel numbers. As a smart, on-grid microinverter, the unit meets CA Rule 21 requirements and is inherent with NEC 2014/2017 (Rapid Shutdown). As with all other microinverters it is applicable for longer working hour and wider PV moduel applications, as its start-up voltage is very low (22V only) and DC input operating voltage range is extremely wide (16-60V).

“The world`s best daisy-chain 2 in 1 microinverter with reactive power control” is designed for two solar panels with dual MPPT, applicable for modules up to 540W, targeting high-power residential and commercial solar applications. With its groundbreaking design and features, the HERF-600 / HERF-800 / HERF-1000 augments your solar system with the highest peak efficiency on the market; lt is also applicable for MW size commercial PV stations (one of the world`s biggest microinverter projects using microinverter is 3.6MW).

The best in its class! The product is designed with reactive power control for 4 solar panels. It offers up to 250% faster installation time than traditional microinverters while with the highest peak efficiency on the market. HERF Series Microinverter has the best power density on the market, which means higher efficiency, greater durability and longer lifetime. In addition to the enormous benefits from industry`s most top warranty and higher production, higher safety with no DC high-voltage makes the microinverter system the best solar solution for residential and commercial applications.

HERF Series Array Level Rapid Shutdown has the functions of automatic power off and reclosing. On the basis of meeting the requirements of fast shutdown function required by NEC2014 690.12, it can ensure the power generation of photovoltaic power generation system to the greatest extent and improve the power generation rate. When the mains power is cut off, the HERF series array level rapid shutdown will automatically cut off the photovoltaic DC power, so that the circuit of the photovoltaic power generation system 10 feet (i.e. 3 meters) away from the photovoltaic array will fall below 30V in 10 seconds; When the mains power is restored to normal, the cascade Rapid shutdown of HERF series group will automatically reclose to restore the power generation of photovoltaic system.

HERF series module level rapid shutdown has automatic power-off and reclosing functions. On the basis of meeting the fast shutdown function requirements of nec217 & nec2020 690.12, it can ensure the power generation of photovoltaic power generation system to the greatest extent and improve the power generation rate. When the mains power is cut off or the emergency stop is started, the HERF series module level rapid shutdown will automatically disconnect the photovoltaic DC power, so that the circuit of the photovoltaic power generation system beyond 1 foot (i.e. 305mm) from the photovoltaic array will fall below 30V in 10 seconds, and the circuit within 1 foot (i.e. 305mm) from the photovoltaic module array must fall below 80V in 30 seconds after the quick shutdown start; When the mains power is restored to normal or the emergency stop is restored, the HERF series module level rapid shutdown will automatically reclose to restore the power generation of the photovoltaic system.
