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?
A combiner box is a key DC distribution device used between PV strings and the inverter. Each string consists of solar modules wired in series, and the combiner box gathers multiple strings into a single output while ensuring safety and system efficiency. Current Collection: Consolidates DC output from 6–24 strings into busbars.
How do I connect the PV string combiner boxes?
To connect the PV strings, the string combiner boxes are equipped with either our SUNCLIX panel feed-throughs or with cable glands on Push-in terminal blocks. SUNCLIX connectors from Phoenix Contact and Push-in terminal blocks combine the advantages of easy installation with reliable and maintenance-free connection.
How many PV string inputs can a combiner box support?
A standard combiner box supports 6–24 PV string inputs, with typical current per string ranging from 10–20A. Key features include: Reverse current protection is essential when module shading or mismatched strings cause imbalance. 2. Multiple Layers of Electrical Safety Protection These protection layers significantly reduce system downtime.
