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.

What is a PV AC combiner box?

PV AC combiner boxes are provid-ed with fuse links in accordance with IEC 60269-6:2010. Each design of PV AC combiner box contains the most suitable fuse rating specially selected for most common string inverters in the market, depending on voltage, ambi-ent temperatures and operation conditions. Material damage!

How are PV DC combiner boxes tested?

PV DC combiner boxes are tested according to IEC-61439-2 and are constructed on the basis of the test results as well as assembled for the specific application. This ensures that each of the requirements of the target application is fully met.

What is a combiner box?

The combiner boxes are in-stalled to connect, gather, collect and protect the AC cable outputs of various string inverters. 1 output, depending on various plant designs. Input of this product ranges from 400 V to a maximum input voltage of 800 V per string inverter.

Do PV AC combiner boxes have a switch disconnector?

PV AC combiner boxes have an AC switch disconnector as an optional component. The AC voltage of the switch de-pends on the voltage of the associated PV string inverters. The switch disconnector (according to the IEC 60947-3) has been selected to assure that it can switch the circuit at full load at the maximum operating temperature.

Which energy meter is used in a PV AC combiner box?

In case the PV AC combiner box is equipped with an ener-gy meter, this device is a D650. This device simplifies the connection work inside the combiner box and reduces maintenance tasks due to the PUSH IN terminals. The Transclinic 16i+ can operate at full load (25 Amps) at maximum temperature range (+70 oC).
