Shoals Technologies Group, a provider of photovoltaic balance-of-system (BOS) components, says it has received ETL certification to UL 1741 for multiple 600 VDC smart combiner boxes with SNAPShot string-level monitoring and integrated DC disconnects.
The combiners feature 12- to 24-string inputs, 250 A and 400 A DC disconnects, reinforced plated busbars, SNAPShot string-level monitoring and NEMA 4X enclosures.
Last month, the company announced similar certification for its 1,000 VDC products.
