PV AC combiner boxes - high quality, optimized, robust and efficient

For solar installations in the PV industry, reliability and availability are paramount. In systems with string inverters, our AC combiner boxes provide optimal short-circuit and overvoltage protection. Furthermore, each string inverter can be easily isolated from the system to do maintenance tasks.

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 60kW up to 200kW and support voltages of 400V, 690V or 800VAC. 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 +50ºC to operate in hardest climate conditions, fulfilling the highest market standards as per IEC 61439-2.
