 OEM service 

How we do the OEM

We have full experience of doing customers OEM products based on our fool-style design and our professional technology parts of controller and inverter, with this core technology as 

the safeguard, we can build up the most mature and professional design for customers very efficient.

With more than 80 models and the components as the prototype, for building customers brand or OEM 

products, customers only need to think about the color and the shape of the box but no anymore together 

with our profession.

Until now weve built many designs for many big customers and governments all over the world, for the 

reason of confidentiality agreement business secret,we can not present too many designs on the website 

or the presentation, but we make sure customers design must be the most mature ,reliable,professional, 

and sophisticated design,becoming the most competitive product on the market.

Here weve got the permission from some of our customers, and give some example of our OEM work.



The payment Terms

We accept the TT, Paypal, Western Union, L/C at sight , ESCROW in Alibaba etc.


The business term

We accept the EXW,FOB, CIF, DDP etc.

Our produce unique and leading advantage than other supplier  

1.  Convenient to maintain:  

2. Low self-wastage, good energy-saving, high stability:    

3. AC systems all adopt the pure sine wave inverter.

The wave shape of the pure sine wave inverter showed by the oscilloscope is much stable than electric supply’s and anti-load capacity is more obvious (600V AC output is enough to start and run fridge), there is incomparable superiority in the industry. Besides, there is also great effect in the dissipation heat. The new design of 300w pure sine wave inverter needn't the cooling fan at all, the rest of specifications of inverters’ cooling fans are all temperature-feeling type cooling fans which need less turn.
4.By 2012, the entire standard products with mature design by our company designed have reached 6 series including more than 80 models; they can satisfy the most of customers’ using requirement. Our product quality and product scale is a leading position on the field.
