How to choose a surge protector – don’t ignore this!
If the high-value information power electronic products in the building, their ability to withstand lightning surges is much smaller than that of basic electrical equipment, it is necessary to use a surge protector to maintain such high-precision electronic products, then how to choose a surge What about protectors? Before selecting a surge protector, be sure to carry out a lightning strike risk assessment and take into account the economics of the project, not only direct losses, but also indirect damage (for information management systems, indirect damage is usually higher than In additio...Read more -
The importance and method of choosing the right photovoltaic DC switch
The importance and method of choosing the right photovoltaic DC switch The quality of photovoltaic DC switches has caused many Australian solar companies to close their doors More and more Australian solar companies have closed their doors due to unqualified OEM PV DC switches. Almost all Australian distributors choose to sell imported cheap DC switches by OEM. Firstly, it is easier to OEM the switches. Only the brand name and packaging are replaced, and the original factory is easy to cooperate. Secondly, these original factories are often small workshops and noth...Read more -

Small devices that should not be ignored in solar photovoltaic systems
A 20MW photovoltaic power station has a total investment of about 160 million yuan. Among them, the investment of the combiner box is less than 1 million yuan, accounting for only 0.6% of the total investment. Therefore, in the eyes of many people, the combiner box is an insignificant small device. However, according to statistical data, the combiner box is an important cause of field failures. Figure 1: On-site failure rate statistics of photovoltaic projects The picture below shows a burnt-out accident...Read more -
