Pre-wired combiner boxes Pre-wired combiner boxes A perfect solution for every customer‘s requirements Combiner boxes are located between the solar panels and the inverter. They join the generated electrical currents together. Weidmüller has developed many standard configurations of combiner boxes based upon recurring customer requirements. These serve not only as an optimal connection system, but also as a reliable protection and monitoring system. The range includes solutions for use in roof-mounted systems up to large solar farms. Specially designed to meet the individual architecture of large systems customer-specific solutions can be implemented where required, quickly and safely. Turnkey delivery We deliver turnkey Plug-&-Play solutions that are ready for installation – making the assembly and installation process as smooth and quick as possible. From roof-tops to solar farms The combiner boxes are available in various configurations for connecting 1 to 16 strings. 38 Pre-wired combiner boxes Optimally equipped Weidmüller offers complete solutions for different requirements. Depending on the version the boxes can contain terminal blocks, surge protection, fuses and switch-disconnectors and even systems that permanently monitor the performance of the strings. Individual solutions Be it a minor modification or a whole new individual product development, our application specialists develop and realise a tailored solution matching your individual requirements. Talk to us! IP 66 Reliable protection Depending on the version the boxes can be protected up to IP 66 which ensures that they are safe to use outdoors. 39 Pre-wired combiner boxes The quick and optimum solution for roof mounted and industrial installations The highest possible returns with the longest possible service life – this is the aim of every photovoltaic system operator. To achieve this target an efficient and error-free facility is essential. To protect photovoltaic plants, Weidmüller offers combiner boxes with surge protection components that can also be fitted with further functional components depending on the requirement. Safety and system availability In a photovoltaic system, the individual modules are connected together in series in so-called strings, that then go into combiner boxes which are fitted between the panels and the inverter. The strings of panels are joined together in combiner boxes and connected with DC main cabling, this then takes the electricity to the inverter. 40 As well as combining the strings, the combiner boxes can carry out various functions, including load isolation, surge protection and even permanent performance monitoring of individual strings or groups of strings. Due to being configured with protection and monitoring components, a combiner box makes a major contribution to ensuring the system is efficient and fault-free. The system operator profits from higher returns and the longest possible service life of the system. Pre-wired combiner boxes Designed, manufactured and 100% tested in accordance with EN 61439-2 In the combiner boxes terminal blocks are used which Weidmüller has tested and approved using a special partial discharge test with DC voltage for 1,000 V DC applications. The surge protection components are also tested for use with 1,000 V DC, and effectively reduce interference-coupling caused by surge voltages. All combiner boxes are tested and certified at Weidmüller‘s central laboratory according to EN 61439-2 for power switchgear and controlgear assemblies. They are also 100% tested after assembly. This makes our installation-ready, plug-and-play solution the perfect system for connecting and protecting solar projects throughout Europe and beyond. Solutions for all needs Based on the comprehensive Weidmüller product range, the combiner boxes are offered with different equipment installed. Significant equipment features are fuse-holder terminals and terminal blocks, surge protection, load-break switches, cable connection technology and modules for monitoring the performance of the strings. Fuse-holder terminals and terminal blocks Specially for use in the PV area, Weidmüller offers terminals that have passed a certain insulation test. It is ensured that the terminals can withstand a voltage of 1,000 V DC under all climatic conditions. More information about the terminal blocks can be found from page 86. Cable connection technology Depending on the version, the combiner boxes are delivered with cable glands or with WM4 PV connectors. This permits a quick and secure connection. More information about WM4 can be found from page 12. Surge protection The surge protection with pluggable highpower varistors can be used in voltage ranges up to 1,000 V and therefore meets the higher demands of photovoltaic systems. More information about surge protection can be found from page 58. String performance monitoring The Transclinic xi+ device series continuously detects the current from individual strings or groups of strings and the voltage. Negative influences, which lead to reduced output, can be detected immediately. More information about Transclinic xi+ can be found from page 28. 41 Pre-wired combiner boxes DC combiner boxes – product overview Number of strings Rated DC voltage Rated DC current per input Degree of protection Surge protection 1 1,000 V DC 30 A IP 66 1 1,000 V DC 30 A IP 66 1+1 (for 2 MPPT) 1,000 V DC 30 A IP 66 1+1 (for 2 MPPT) 1,000 V DC 30 A IP 66 2+2 (for 2 MPPT) 1,000 V DC 10 A IP 44 2+2+2 (for 3 MPPT) 1,000 V DC 10 A IP 44 3 1,000 V DC 12 A IP 66 3 1,000 V DC 10 A IP 66 3 1,000 V DC 10 A IP 66 3 600 V DC 10 A IP 66 4 1,000 V DC 11 A IP 66 4 1,000 V DC 11 A IP 66 4 1,000 V DC 11 A IP 44 4+2 (for 2 MPPT) 1,000 V DC 8A IP 44 8 1,000 V DC 12 A IP 55 8 1,000 V DC 15 A IP 55 12 1,000 V DC 13.3 A IP 55 14 1,000 V DC 11.4 A IP 55 16 1,000 V DC 10 A IP 55 16 1,000 V DC 10 A IP 55 • • • • • • • • • • • • • • • • • • • • 42 DC Fuse holder available switch-disconnector • • • • • • • • • • • • • • • • • • • • • • • • Pre-wired combiner boxes Cable gland (CG)/WM4 plug-in connector String monitoring Part No: 7504811010 CG Part designation PV DC 1IN SPD CG 1000 V Technical data on page 44 WM 4 7504811001 PV DC 1IN SPD WM4 1000 V 44 CG 7504811011 PV DC 1INx2 2MPPT 2SPD CG 1000 V 45 WM 4 7504811002 PV DC 1INx2 2MMPT 2SPD WM4 1000 V 45 CG 7504811012 PV DC 2INx2 2SW 2MPPT 2SPD CG 1000 V 45 CG 7504811013 PV DC 2INx3 3SW 3MPPT 3SPD CG 1000 V 46 CG 7504811014 PV DC 3IN SPD CG 1000 V 46 WM 4 7504811005 PV DC 3IN SPD WM4 1000 V 47 CG 7504811015 PV DC 3IN SW SPD CG 1000 V 47 WM 4 7504811006 PV DC 3IN SW SPD WM4 600 V 47 CG 7504811016 PV DC 4IN SW FH SPD CG 1000 V 48 WM 4 (inputs) / CG (outputs) 7504811007 PV DC 4IN SW FH SPD WM4 1000 V 49 • 7504811009 PV DC 4IN SW FH SPD CG 4i+ 1000 V 48 CG 7504813008 PV DC 4+2IN 2SW 2MPPT FH 2SPD CG 1000 V 49 CG 7504813009 PV DC 8IN SW FH SPD CG 1000 V 49 7504813002 PV DC 8IN SW FH SPD CG 8i+ 1000 V 50 7504813010 PV DC 12IN SW FH SPD CG 1000 V 50 CG CG • CG CG • CG CG • 7504813003 PV DC 14IN SW FH SPD CG 14i+ 1000 V 51 7504813011 PV DC 16IN SW FH SPD CG 1000 V 51 7504813004 PV DC 16IN SW FH SPD CG 2x8i+ 1000 V 51 43 Pre-wired combiner boxes PV DC 1IN SPD CG 1000 V PV DC 1IN SPD WM4 1000 V Technical data Enclosures Dimensions (H/W/D) Attachment method Degree of protection (according to EN 60529) Electrical properties 190 x 184 x 106 mm 190 x 184 x 106 mm Direct wall mounting with mounting lugs Direct wall mounting with mounting lugs IP66 IP66 Max. open circuit DC voltage Max.
