How to open and clean your CNBOU inverter?

We saw a video from a customer, we don’t know where this 600W inverter is used, but the outside of the inverter fan is very dirty and has rust, CNBOU’s inverter fans are designed to be extracted type, meaning that the air with low temperature in the environment is extracted to the inverter to cool the components... » read more

How much current does a 2000w inverter draw?
How much current does a 2000w inverter draw?

In a small off-grid solar system, considering the cost, usually the customer’s battery capacity is not very large and the solar panels equipped are not particularly large. Choosing a good inverter will become very important. If the inverter you choose is a low frequency inverter, then the inverter’ comsumption will drain your batteries, let’s take... » read more

12VDC 6000W update to 24VDC, Is it possible?
12VDC 6000W update to 24VDC, Is it possible?

We saw another amazing user on Youtube, he converted a 12VDC 6000W pure sine wave inverter to 24VDC, this is a crazy act, we don’t recommend any customer to do this, it’s a very professional job, of course we know he is a technical enthusiast.(this 12Vdc 6000W pure sine wave inverter made in 2016). In the video,... » read more

Electric welding machine – 3000W inverter load test

We once reported a blogger from Youtube one year ago: Small City Homesteaders, used CNBOU BP series 3000W pure sine wave inverter in his off-grid solar system. We still remember that he thought CNBOU was made in Japan. We later correct it that CNBOU is a Chinese company. We thank him for his recognition of CNBOU inverters.... » read more

Which inverter is best sine wave?
Which inverter is best sine wave?

A good inverter, its output waveform must be good, which will be very helpful to the life of the load. It is suprised that we can see many inverters on the market are marked with THD<5%, and they are even high frequency inverter. They use inferior components and cost saving designs, in result, although we... » read more
