works perfect with Huawei
Emre Yılmaz Sunturk -
We installed it in our solar system and it communicates with the Huawei inverter as expected. Good solution for this price.
Andrei Popescu -
We needed a 250A meter for our installation. The SM24 was a good fit and it works as expected with our Huawei system.
Daniel Fischer -
Installation was straightforward and the readings look good. A good alternative for our installation.
M. Rossi -
Good value for the money. We installed it in a three-phase system and everything is working fine so far
Thomas Berger -
The meter gives us the information we need for our PV system. Setup was not complicated and it has been working fine.
Carlos Mende -
We use it with a Huawei inverter in a commercial installation. It does the job and the 250A capacity was important for us.

We were looking for a meter that works with Huawei without paying too much for the original one. So far, no problems.
