What Is A Micro Inverter? Dc Cable Connector Is The Future
‘DC Cable Connector’ vs. ’board end connector’
The rapid development of micro inverter in recent years in the world, thanks to the countries on the safety, high efficiency, convenient more and more attention, and then there are more and more manufacturers into the micro inverter track, we have a different understanding of the market demand, but also derived from different product design solutions. Today we mainly talk about the differentiation of DC output, the mainstream DC output, there are two main schemes, one is led by some of the head brand DC cable Connector scheme, one is led by some of the important brands of the end of the board end connector scheme, what is the difference between the two connector scheme, what kind of impact will there be in the actual installation?
I. Board end connector – Optimise structural costs
Installation: The board end connector is fixed on the sheet metal, which is more cumbersome and less flexible to cope with the complex installation environment.
Reliability: The plate end connector requires more waterproof technology and high processing requirements for the factory. Damage rate: In the complex installation and harsh transport environment, the plate end connector is more likely to have the risk of being broken, so the design of the plate end connector must use reinforced materials. After-sales: If the board end connector is damaged, the whole machine needs to be replaced, which is more costly after-sales. Price: The end-of-board connector has less DC wire harness cost, so the overall cost is more advantageous.
II. DC Cable Connector – Make installation more convenient and after-sales more worry-free
Installation: In the actual situation of roof installation, the DC terminal block has more operational flexibility, making installation easier. RELIABILITY: Higher waterproof level, more stable and reliable. Damage rate: the flexibility of DC wiring harness can adapt to the harsh transport environment, not easy to damage. After-sales: If the connector fails, you can directly cut it off and replace it with a new one, which makes the after-sales more hassle-free. Safety standards: with DC wire connectors, the test requirements for EMC are higher, and the process requirements for factory production are also higher. (This is the core reason why many manufacturers don’t choose DC line connector, EMC test is hard to pass)
Leading the way to a new future in PV
On the whole, the advantages of DC terminal solution outweigh the disadvantages, but as the market competition is getting more and more fierce, more and more manufacturers choose the more cost advantageous board end connector solution, in addition the board end connector package size will be smaller, the logistics cost will be reduced, which attracts a large number of manufacturers to ignore the long life design requirements of the micro inverter itself. As a core component in the PV power generation system, the Micro Inverter converts DC power into AC power and plays an indispensable role in the PV power generation system, so the micro inverter system is generally required to have a design life of 25 years. In addition, as a financial investment project, it is suggested that in addition to considering the price, we should consider the reliability and stability of the long-term system operation, once there is a failure, the loss of electricity costs are incalculable. Lefor Energy has always adhered to the concept of ‘making installation easier’, and has been catering to the market in the field of microinverter technology, continuous innovation, with the advantages of convenient installation, safety and efficiency, and cost leadership!
