Technical FAQs 4

What is a PV AC combiner box?

The new PV AC Combiner boxes have been designed for PV systems with string inverters in trackers or fix tilt systems.The product portfolio is suitable for inverters from 60 kW up to 200 kW and support voltages of 400 V, 690 V or 800 V AC. The combiner boxes allow to collect from 2 up to 6 string inverters in one single cabinet.

What is a combiner box?

Combiner Boxes provide a secure, economical and code compliant method of combining multiple PV source circuits into one circuit. The combiner box also provides a convenient location to begin the necessary conduit run from the PV array to the power conditioning equipment.

What is a DC combiner box?

DC combiner boxes link PV inverters and PV arrays, combining the output of a large number of strings to improve PV performance. Through the design of our combiner box, we enable easy integration of additional functions, such as the inclusion of switches and a second MPPT.

How many string inverters can a combiner box collect?

The combiner boxes allow to collect from 2 up to 6 string inverters in one single cabinet. They withstand ambient temperatures from -20 up to +50°C to operate in hardest climate conditions, fulfilling the highest market standards as per IEC 61439-2 ed 3.0:2020.
