Incorrect grid export limit unit and range on MS Series #111
Comments
Can you please paste screenshot from the SolarGo where it is begin set ? |
I see that it has been removed in this commit in the latest version of the package. I was scratching my head as to why it wasn't working in the official HA integration 😄 Btw the time sensor above never worked for me. It's probably a different register. |
Quick update on the inverter time Looking at the packet trace from SolarGo, I have been able to receive the inverter time from register 30100(0x7594) Timestamp("time", 30100, "Inverter time"),
Integer("shadow_scan", 40326, "Shadow Scan", "", Kind.PV),
Integer("grid_export", 40327, "Grid Export Enabled", "", Kind.GRID),
Integer("grid_export_limit", 40336, "Grid Export Limit", "W", Kind.GRID), gives the following values

Perfect, finally someone who can verify the MS/DT family behavior ! |
👍 Do let me know if you need additional information. |
I switched the grid_export_limit to % for DT inverters. |
Do you have instructions on how to go about testing that? Now that goodwe integration is part of HA 2022.2? |
I get this on HA 2021.12
|
HACS version now needs HA 2022.2. |
Thanks for that. This is the error on 2022.2 with master checkout of the plugin:
|
OK, that was my mistake. |
I downloaded the latest master and it looks good now. Entity History |
Yes, the W unit is very likely caused by history records of the entity with same name. |
I can confirm that was a relic from when the entity was previously configured. Deleting the entity from the HA db and restarting fixed the unit to Could you please look at bringing back get/set of the Thanks again for being so responsive. |
Well, the inverter time at register 30100 is the read-only register (and is already being provided as sensor as part of the get_runtime_data call). |
I can confirm Here is the complete packet that was sent out by SolarGo.
Let me know if you need more data with regards to this. |
Do you want me to run additional tests @mletenay ? |
Hi guys, I found the same issue in my Goodwe GW5000D-NS. I mean the grid_export_limit (number.grid_export_limit) was set in % but after verify really is Watt, for example:
I´ll try to change the attributes setting the Power = 5000 (according my Inverter model) and adjusting the unit of measurament to Watt but I receive a error from HA, understand must to me adjusted by the owner of the integration :) In this way (Maybe must to be a new one post/discussion) trying to control the exported energy to the grid (want to be ~0) and considering this model of Inverter can´t control the zero exportation I made some adjustments manually in SolarGo in order to "control" the energy exportation adjusting the Power Limit Value: I have the Shelly Power Meter integrated in my HA, then I can see the power generated by the solar panels and the power of the grid (Negative means inyection to the grid). Other example: |
@carlodie This is really weird and D-NS specific ?? |
Hi @mletenay I don't know about the other series or families, but in my D-NS (LCD screen) and SolarGo APP the set is in "Watt" but in Home Assistant integration figures/apper in "%" but really the setup is in Watt. This must to be adjusted in the code of Home Assistant Integration right? @aksvenk do you had a similar case before? |
Hi All Can I ask what the outcome of this was? I have the same 8500-ms inverter and trying to use the export limit but it is showing in watts not percent and when I try and set it I get an error |
Hello,
I have a Goodwe GW8500-MS. The grid export limit on this unit is set in percentage(%) of the rated power.
eg. Setting the export limit to 60% will cap the export at 5.1kW (60% of max AC power rating of 8.5kW).
I have tested the slider of the export limit on v0.9.8.1 of the plugin and I can successfully set 100 and 0 as the grid export limit value. It also gets the right value from the inverter.
Any chance the range of the export limit can be adjusted based on model or by querying the capability of the system?
Thanks
