IntelliString™ Smart Combiner Box
Quality, Accuracy and
Ease of Installation
PV Powered makes string combiner monitoring easy and affordable with
the IntelliString™ line of smart string combiner boxes. Installer friendly
features including touch safe fuses, solid bus bar and bridge punched
back panels assure that this smart string combiner box will install quickly
and last the life of the PV system. String current monitoring is enabled
by the integrated DC Solar Current Monitor from Obvius. The DC Solar
Current Monitor was selected for its robust and easy to use design,
modbus output and built-in user settable alarming functions which
simplify data collection and reporting.
String-level performance data is a valuable tool for PV system owners
because it enables fast diagnosis of PV system underperformance due
to failed modules, shading or soiling. Until now this important tool
was primarily used on large expensive systems due to the high cost of
monitoring at the string level. Now the IntelliString™ line of smart string
combiner boxes offer a solution that is practical and affordable enough
to use on all commercial installations.

New! String Combiner Boxes
PV Powered’s DC String Combiner Boxes
are Reliable, Safe and Convenient
The new PV Powered DC String Combiner Box provides a means of
combining multiple source circuits from a PV array into a single DC
output. Each source circuit is fused separately using a touch-safe
fuse holder. The combiner box allows for fail-safe operation of the
system in the unlikely event that a problem with a source circuit leads
to abnormally high current. In addition, the combiner box provides
a convenient means of accessing the DC portion of a PV system for
routine maintenance and troubleshooting.
