How to change the output frequency of Huawei ETP23012-C2A1

ETP23012-C2A1 Solution

Recently, we’ve received feedback from customers asking how to adjust the output frequency on the Huawei inverter ETP23012-C2A1. As you know, the default grid frequency in China is 50Hz, but different countries may have different grid frequencies. Today, we’ll be testing and verifying the method to change the output frequency accordingly.

Huawei ETP23012-C2A1 official data only states that it supports 50Hz output.

But the label says it supports 50Hz and 60Hz output.

The inverter is a very simple device. We didn’t find where to set the parameters and select the output frequency.

Based on our past experience, we linked the inverter ETP23012-C2A1 to a Huawei power converter ETP48400-C4A1, which has SMU02C monitoring.

After testing, we know how to change the output frequency of the inverter. In summary, most of the parameter functions are changed in monitoring.

I hope this article is helpful to you.
