That is Enphase’s first microinverter powered by gallium nitride (GaN) expertise and designed for three-phase 480-Y/277-V grid configurations, with out utilizing exterior transformers.
The IQ9N-3P is designed for 480-V business tasks. It makes use of GaN expertise within the energy conversion stage as an alternative of silico to extend the system’s effectivity to 97.5%. It could possibly handle a steady DC present of 16 A and ship as much as 427 VA of peak output energy, supporting photo voltaic panels as much as 600 W.
“Now we have rigorously vetted the Enphase IQ9N-3P Microinverter and are excited to put in it on many business tasks over the subsequent a number of years,” mentioned Jon Wedel, co-owner and VP of business at Namaste Photo voltaic, a seasoned Colorado-based employee-owned cooperative. “Due to the brand new 480-V resolution, we are able to pursue many extra easy purposes and set up these techniques extra effectively. The U.S. manufacturing and home content material qualification makes navigating the present market a lot simpler whereas delivering a top-quality, reliable resolution for our shopper base.”
The brand new microinverter is compliant with grid requirements together with UL 1741-SB and IEEE 1547-2018, and options fast shutdown, section balancing, voltage/frequency ride-through and loss-of-phase detection for grid security and system reliability. Enphase business techniques are designed to assist UL 3141, a system-level normal for protected, coordinated management of energy circulate. That is doable by way of Enphase Energy Management software program and doesn’t require exterior safety {hardware}.
Enphase IQ9N-3P Industrial Microinverters might be deployed on techniques rated at lower than 100 kW or lots of of kilowatts. Enphase microinverters supply module-level monitoring and may preserve manufacturing below shading and uneven roof situations, akin to business rooftops with HVAC obstructions, skylights and multi-tenant layouts.
“GaN expertise and three-phase assist make the IQ9N-3P Industrial Microinverter a robust match for contemporary business rooftops,” mentioned Drew Collom, co-founder of High quality Photo voltaic. “With manufacturing in the US and home content material alignment, we are able to design extra environment friendly techniques, meet federal sourcing necessities and scale tasks over time with out pricey redesigns.”
IQ9N-3P has a 25-year restricted guarantee, whereas IQ Gateway Industrial Professional, Enphase’s business monitoring hub, comes with a 15-year restricted guarantee.
