CNKA string combiner box Feature

Users can connect photovoltaic cells of the same specifications in series to form a photovoltaic series connection. Multiple photovoltaic modules connected in series are then routed through the lightning protection box of the PVB series photovoltaic combiner, where they are consolidated. Within this combiner box, lightning arresters and circuit breakers manage the output and transmit energy to the photovoltaic inverter, thereby creating a complete photovoltaic power generation system. This approach simplifies system wiring, enhances system security, and offers customers safe, straightforward, aesthetically pleasing, and practical photovoltaic system products.

CNKA string combiner box FAQ

Q: What is the advantage of a combiner box?

A: CNKA's combiner box is a cost-effective solution that simplifies cable management, reduces material and labor expenses by consolidating multiple cables connected to the inverter. Additionally, installing a combiner box provides an extra layer of protection against overvoltage and overcurrent, safeguarding the inverter from potential damage.

Q: What does a DC combiner do?

A: CNKA's DC combiner is a device used in photovoltaic systems to combine multiple inputs from DC circuits, such as from solar panels, into a single DC output circuit.

Q: What is the difference between AC and DC combiner boxes?

A: The DC combiner box integrates multiple PV strings and panels, offering multiple input options and distributing current to several inverters for multiple output possibilities. In contrast, the AC combiner box typically provides only one additional output. The primary function of both types of combiner boxes is to consolidate current.
