SMA is now taking orders for its latest central inverter, the Sunny Central 2500-EV-US, which the company says is certified to the new UL 62109 standard and is ideal for 1,500 VDC utility-scale applications.
The Sunny Central 2500-EV-US provides 2,500 kVA at 1,500 VDC, allowing developers, owners and EPCs to benefit from cost reductions due to balance-of-system savings, according to SMA. The company says also says it the first manufacturer to have an inverter certified to UL 62109 by UL LLC. This new safety standard is specific to the solar industry, addressing the unique aspects of applying power conversion technologies to photovoltaics.
“As we move toward a smarter, more efficient modern energy grid, it remains critical to include safety considerations in product development, while also focusing on harmonization,” says Jeff Smidt, vice president and general manager of UL’s Energy and Power Technologies division. “UL 62109 certification aligns with those goals while also supporting necessary cost efficiencies in the market.”
Furthermore, SMA says the Sunny Central 2500-EV-US inverter saves costs by reducing the size of the DC cabling, as well as the quantity of combiner boxes and medium-voltage equipment required. Additionally, fewer system components are needed per inverter pad due to the integrated DC fuse servicing switches and convenience power.
“CAPEX reductions are imperative to maintaining margins and staying competitive in the utility-scale PV landscape,” says Marko Wittich, SMA executive vice president of sales for the Americas region. “Utilizing 1,500 VDC system design with the Sunny Central 2500-EV-US allows stakeholders to realize an immediate impact to their bottom line.”
