A plug & play solution for solar installations In a photovoltaic system, the modules are arranged in strings and fields depending on the type of inverter used, the total power and the technical characteristics of the modules. MANHUA offers a plug & play solution that accommodates over current protection devices, disconnections and surge protective devices (SPDs) in one solar combiner box. Depending on the application, combiners are equipped with monitoring devices to measure current, voltage and temperature to ensure the availability of the strings and to maximize generation. The string combiner boxes form subsystems that can be standardized according to the number of strings, voltage and rated current. Main benefits 搂 Solar string combiners boxes improve safety of solar panels and the entire photovoltaic plant 搂 Solar combiner box, also called DC switchboard, as plug and play solution factory-assembled with the monitoring device, fuse disconnectors with fuse links, surge protective devices and switch disconnectors 搂 Global availability ensures on-site delivery at any part of the world 搂 Six different enclosure sizes flexibility to cover the range up to 32 strings Main Features 搂 Solar string combiners boxes solutions for all residential, commercial and utility-scale applications with single string, or up to 32 strings in 1000V and 1500VDC; monitoring optional 搂 Solar string combiners are built with Gemini thermoplastic outdoor enclosures due to its great mechanical strength 搂 Protection against dust, heavy seas or powerful jets of water, chemicals and high UV rays thanks to its mechanical features: IP66, IK10 and GWT 750掳C 搂 Electrical features: double insulation (Class II), Ui/Ue: 1000V DC/1500V D 搂 Depending on site conditions Gemini enclosures can be floor standing or wall mounted The Solar string combiners boxes monitoring is an important function in running medium and large size installations, since it allows to improve the efficiency and maintenance of the system. ABB also offers prewired solar combiner boxes with not only string protection, surge protection and disconnection but also with additional monitoring devices. The monitoring device CMS PV collects all main information such as string current, voltage and temperature in one device. The installation of a photovoltaic system often occurs in complex logistic situations, critical from an environmental and time perspective. In order to avoid time consuming on site assembly, wiring and certification activities, ABB provides a plug & play solution: The string boxes' pre-assembled components enclose functions such as string protection, protection against overvoltage and disconnection, with components suitable for the string鈥檚 various voltage levels and the number of connected strings. Mainly in residential applications the number of multi-string inverters has been increasing.
