Hi All,
I am planning to install ESA Goodwe Solar + Battery System .
Comparing to Sigenergy , i cannot find much information for HA integration , VPP Controlling .
I appreciate further details from expert HA members.
Thanks 
Hi, I’m a newbie with Home Assistant. So here’s my two cents.
I just had my installed few days ago and only been trialling it. There is so many information about different goodwe system and it’s integration but nothing on EHA SERIES. And since you’ve started this thread, I thought I would contribute and hopeful others out there might share their set-up with this series to help tweak a few things.
I’ve set up my system fairly similar to other goodwe series. Except that I don’t have an eco mode. I have TOU mode (which is the same thing but renamed). In this TOU mode, it let’s you set time periods to charge or discharge to the grid. So I’ve just set my time period to 0:00 to 23:00 all year round, with Max discharge 90% of my rate.
Side note, the operation mode (or working mode) will switch between TOU and self use mode between your time period setting.
In home assistant, I use the “experiential Goodwe inverter” integration via HAC. Once set up, I have my “Inverter Operation Mode” in “General Mode” (unlike many other threads where they’ve set it to Eco discharge mode and switch back to general). Then I mainly turn on my “grid export limit switch” and set a export limit.
Anyway. Hope that helps…
Hi Tom ,
This is really helpful .
Could you share the entities mapped in HA as well ?
Thanks
Hi, a week ago a GoodWe GW9.999K-EHA-G20 inverter and GoodWe GW8.3-BAT-D-G21 battery were installed, but the installer did not explain or provide any instructions on how to use the app. Could you please tell me where I can find Eco / TOU mode and provide instructions for setting export limits and time schedules?
This system does not support the Amber Smart Switch, so I cannot control exports during peak times. A couple of providers offer peak-time tariffs between 5:30 pm and 7:30 pm, and I would like to set an export limit so that my battery does not drain during these hours.
I would appreciate your help with these settings.
Regards
Kiran
I’m considering purchasing what seems to be a near identical setup.
I’m also hoping to be able to change the configuration (export mode, time limits, thresholds) via HA, and will be aiming to add also an EV charger (GW7K-HCA-20) which I’m led to believe by Google that can also be controlled from HA through the Inverter.
@Kiran27 if you haven’t already found it, it seems that the primary requirement to ensure that it’s detectable by HA is to ensure that “Modbus TCP” is enabled in the settings from the App (not sure which section sorry, possibly advanced).
I also noted that the EHA-G20 (ESA series!?) wasn’t yet supported by Amber, though it appears that a trial has been completed and there’s a waitlist process to hopefully get on board here: Amber&GoodWe VPP integration initial limited release announcement-News-GOODWE
I’m keen to learn more about what is exposed, and note that it seems that the HACS version GitHub - mletenay/home-assistant-goodwe-inverter: Experimental version of Home Assistant integration for Goodwe solar inverters has documentation about setting up cumulative energy sensors (for that version).
