solar energy Smart combiner boxes

PV Powered’s IntelliString line of smart string combiner boxes were developed to provide PV system integrators with a reliable and easy way to implement string monitoring that is affordable enough to use on every commercial PV system. String-level performance data is a valuable tool for PV system owners as it enables quick diagnosis of system-level underperformance due to failed modules, shading,

or soiling. Until now, this tool was primarily used on large, expensive systems due to the high cost of string-level monitoring hardware and the complexity of the installation process. The IntelliString smart string combiner boxes are offered in both 8-string and 16-string versions. The products are UL1741-listed and have many installer-friendly features including touch-safe fuse blocks, a NEMA 4X fiberglass enclosure, and powder coated back pan with

integrated wire management. PV Powered has selected the Obvius DC Solar Current Monitor to enable the smart string current monitoring. The Obvius DC Solar Current Monitor was chosen for its robust and easyto-use design, Modbus output, and built-in user-selectable alarming functions, which simplify data collection and reporting.

Smartech International supplies PV module laminators with Steinbach Silicone Diaphragms from Germany. Smartech stocks both Steinbach’s high-quality solid silicone, as well as their patented Lamibran two-ply diaphragm in Charlotte, North Carolina. Steinbach’s Lamibran has proven its value and durability around the world. The patented second layer does not become brittle like standard silicone when exposed to EVA outgassing, which greatly increases the longevity of the diaphragm. Steinbach will quickly manufacture a custom specific size, and Smartech can arrange to stock what is needed for the convenience of prompt delivery times. A variety of PTFE release sheets are also available—custom cut and punched to specification. Smartech International LP www.smartechonline.com
