Since

1937 CITEL, Inc. has been specializing in the manufacturing of reliable Surge Protection Devices (SPD). CITEL has since expanded its surge protector lines to protect Grid-Tie Solar Power Systems. CITEL's DS50PV is surge rated at 40kA 8/20us, and engineered to protect against indirect lightning, AC utility grid surges, and internally generated switching transients. CITEL model DS60PV is a Heavy Duty DC surge protector, rated to withstand a direct lightning strike (10/350us waveform) as defined by ANSI/IEEE C62.41-2002 and IEC 61643-11. It is typically installed at the DC input to the inverter of a solar power system. These din rail mount devices can be integrated into a PV combiner box or standalone enclosure. CITEL is also pleased to announce model DS50PV as the first UL recognized DC Surge Protector with replaceable modules.

Introducing RockIt Smart Slide

Introducing RockIt Smart Slide - the ultimate solution for fast and easy installation of the rail-less RockIt racking system on composition shingle roofs. Smart Slide conforms to UL 441 and TAS 100 (A)-95 for wind and wind-driven rain, providing a super-strong watertight seal that is achieved through compression, in most cases without the need for additional sealant. The waterproofing sealant is embedded deep into the granules of the shingle, thanks to the integrated flexible foam layer that provides cushioning. This ensures a secure fit that conforms to any architectural-style shingle. With UltraGrip Technology™, you can rely on a secure installation, as it absorbs the movement created by thermal expansion and contraction. The pre-installed sealing pads are compatible with all composition shingle roofs, making it the ideal choice, even in ambient temperatures as low as 5 degrees.
