What is a DC combiner box?
Our DC combiner boxes offer users the possibility to integrate short-circuit and overvoltage protection, as well string monitoring solutions (I,V, T and SPD and switch isolator status), for PV systems using central inverters with PV panels in trackers and fix tilt systems.
Are PV DC combiner boxes CE-compliant?
The PV DC COMBINER BOX is CE-compliant in accord- ance with Directive 2014/35/EU (Low Voltage Directive) and with Directive 2014/30/EU (EMC Directive). PV DC COMBINER BOX is a complete range of tai- lor-made Level 1 combiner boxes for utility-scale photovol- taic systems.
What is a solar combiner box?
The combiner boxes are installed to join and protect the DC strings that go from the PV panels to the solar inverter. The PV DC COMBINER BOX product range offers solu- tions from 8 to 32 inputs and 1 or 2 outputs. These can be designed for systems with string voltage of 1000 or 1500 V DC.
How many kV is a PV combiner box?
Special units for 1 kV or 1.5 kV are used to provide the best performance in each specific system configuration. The PV DC COMBINER BOX has a DC disconnection switch by default. The DC voltage of the switch depends on the voltage of the PV string.
How to connect a PV DC combiner box?
Pull down the cables to assure that all of them are well connected. The output connections depend on the design of each tailor-made PV DC COMBINER BOX. The output cables must be connected to the poles of the switch disconnector or to the terminals prepared for this purpose.
How many inputs & outputs does a PV DC combiner box have?
The PV DC COMBINER BOX product range offers solu- tions from 8 to 32 inputs and 1 or 2 outputs. These can be designed for systems with string voltage of 1000 or 1500 V DC. The necessary string cables (+ and -) are to be connected at the inputs whereas one or two DC+ and DC- main ca- bles will be at the output side.
