Huawei Inverters

English Forum

Hello everybody, first-time post here!

We are experimenting with the pre-built OpenEMS version running on a Raspberry Pi.

At the moment, we have connected a Shelly PM and an SMA inverter, and everything is working fine.

Now we would like to connect a Huawei SUN2000 inverter and possibly a Luna battery, but there’s no controllers available. Are there any add-ons we can install, or is developing our own controller the only way to integrate Huawei products?

Thanks in advance!

In this case, yes as there is no driver for this.

Thank you Sn0w3y for the carification.

Maybe could you clarify further what your Use-Case is and from which Company you are joining? :slight_smile: At OpenEMS we always want to hear from the Storys of our users ! :slight_smile:

Hi Sn0w3y,

we are a power distribution company. We are testing various solutions that allow to control energy loads at the customer’s side.

We wanted to know if Huawei was integrated in the pre built version of OpenEMS since we have available a complete Huaewi setup (inverter, battery..) and Huawei is a widely diffused manufacturer.

Thanks for providing some details - and I am glad to hear that some basic tests were already successful.

Just a note here: yes, Huawei is widely used and it seems the Modbus protocol is sufficiently documented online.

It should be fairly easy to implement it, if you have one available:

These kind of projects are often well-suited for an internship or bachelor thesis :wink:

Hi @piM,
there is no need to implement the device. We already have an implementation for the Huawei 2000 and the Huawei 2000 accessed via Smartlogger:

Just need to clean it up and do a PR. Should be possible until Wednesday.

@c.lehne: Great. One early note: please change the namespace to io.openems.edge.huawei, because there is going to be much more than just PV-Inverters.

Hello everyone, Hi @piM,

We created the PR feel free to edit / improve

Important note (as mentioned in the PR)
We started to implement the Huawei PV Inverter, after the skeleton/implementation of registers/component was done, the system we originally planned to use this, switched to the SmartLogger.

Therefor the PV Inverter is not tested but the SmartLogger is.

Hope this helps.

Thank you all for the infos.
