Photovoltaic Protection Made Simple

Photovoltaic Protection
Made Simple
The Intelligent Solution to PV System
Protection
• Designed for harsh environments, the Cooper Bussmann combiner box
has superior thermal characteristics eliminating the need for forced
ventilation in extreme ambient temperatures.
• Completely customisable from 3 to 24 strings offering genuine PV
circuit protection with Cooper Bussmann industry leading gPV fuses in
ratings from 1A to 32A up to 1000VDC, PV overvoltage surge protection
and true PV DC rated disconnect switches.
• PV system performance and combiner box status can be remotely
checked with a choice of monitoring solutions including wireless
communications and a range of power supply options.
• Engineered to make installation and operation safe and easy, each
combiner box is fully IEC compliant with options for MC4 connectors,
interlock handle, and all monitored units incorporating an external
Modbus connector for quick diagnostics. All this wrapped up in durable
IP65 rated enclosures as standard.
• With a global manufacturing base and an integrated common system
approach, Cooper Bussmann can locally develop and manufacture
customised combiner boxes within competitive timeframes while
maintaining exceptional levels of quality.
