As we all know, inverter is the heart of the solar system. And there are high frequency and low frequency inverter in the market, with difference advantage and disadvantage.

We have a customer, he has a high frequency inverter in hand, but he wants to buy our low frequency inverter to replace exist.

Here is his feed back of the exist high frequency inverter:

He doesn’t like the high frequency inverter because there is no copper transformer built inside, that’s why the weight is light and working not stable.

This is our low frequency inverter, with large transformer built inside, make sure output stable and strong and reliable.

Here is another customer feedback on the high frequency inverter.

He believes that electrical device is better with large components and heavy weight.
