Applications and Markets

Suitable for PV system, equipped with a surge protector and an isolator,providing isolation, leakage and grounding protection.
Onccy new energy uses combiner boxes to support you with very flexible system design.
In ground-mounted solar power plants, the inverters are installed at a central location, while the DC combiners are spread across the PV module array. This leads to short cable runs between the inverters and the transformer and means that there is only minimal loss of power on the AC side: The high efficiency of our inverters can be deployed to its fullest. In commercial and industrial PV systems, this kind of design makes it possible to avoid AC lines on the roofs.
