1, the system power supply is not stable;
2, the system capacity is not worth badly;
3, each parts of system application for about a year, frequent breakdown;
4, system two years, generating capacity decline day by day. Then, fan in the vast number of consumers in mind to sell at a discount greatly. So today, said fan, herdsman people shook his head. Structurally, the fan has the advantages of simple structure, easy to accept, from the operation principle, the stability is very difficult to control fan. Combined with human interest drive, to the user, is difficult to be guaranteed. The increasing prevalence of Pu Tai Group of experts, combined with years of technology and experience, from the whole system design, fully consider the use of the prone, frequent specific issues, the fan blades, generator, tail, assembly and other aspects of strict screening, strengthen manufacturing process, each technology index optimization.
Up to now, in the hands of customers with thousands of products, with no problems.
