Photovoltaic Combiner Boxes Company Customer Service Leading Source of Circuit Protection Ease of Doing Business, Quality and Delivery Optimize your solar power generation capacity through the reliability and expertise of a Cooper Bussmann protected electrical system. Building on an existing range of dedicated photovoltaic (PV) products the Cooper Bussmann Combiner Box can be used across a range of PV powered distribution networks to ensure maximum system protection. Quality Driving Continuous Improvement From design conception to the end product quality is paramount to the safety and reliability of Cooper Bussmann products. Rigorous testing to ensure global standards are met, help ensure the highest levels of quality throughout the entire product range. Customer Service Representatives and Field Application Engineers are on hand to help with specific customer needs offering custom technical solutions. Along with our technical support the Cooper Customer Centre, C3, is the online solution designed to provide real-time product availability, net pricing, order status and tracking. It's simple, fast and accurate. Innovation Leveraging Technology to Drive Customer Value Cooper Bussmann recognises the need to continually innovate and develop new technology to meet the changing needs of the market. Utilising over 100 years of circuit protection experience, Cooper Bussmann produces technical products into technical solutions. By expanding the PV product portfolio we are able to offer complete protection for your PV power distribution network. Residential Commercial Systems Residential system typically have up to four PV strings. Systems of this size should have the same level of protection and safety as larger installations. With DC switch disconnect, fuse protection and PV surge protection you can be sure the Cooper Bussmann Combiner Box will provide the necessary protection to the PV system and operating environment. Commercial roof type installations have a larger number of options based on the installation design. Owing to the higher power generation and increased installation size, these systems have increased string counts requiring larger combiner boxes and higher system current ratings. Scaling with the needs of these systems the Cooper Bussmann Combiner Box provides DC switch disconnection to isolate the PV array from downstream components, critical for safe system maintenance. Positive and negative PV fuses protection safeguards the PV panels from overcurrent faults and protects downstream cables, minimizing fire hazards. As with residential installations, a surge protective device provides protection of the sensitive PV panels from overvoltage surges and spikes.
