Thanks Cef Got it working by replacing the Historic.dbf file. My weather app is still working, in my opinion being able to see the next days weather would also be useful especially if rain is forecasted. I'm now getting error messages regarding the weather on 2 Jan 26, I've turned the weather off the weather option and it now works fine (I'm sorry to hear that you upgraded😂).

hi @Cef Compliments of the season. Is there any reasons why this version of your software stopped working? It was still ok at 20h00 yesterday. I still use it daily.

Hi Bobster, I've not been on the site for a while. I logged a fault on the Goodwe website on Sunday 18 th May and called them the next day. Sisanda from Goodwe help desk ran some remote checks and within a hour gave the following feedback. "the inverter appears to be physically disconnecting from the grid. We have reviewed the settings on our side, and everything is configured correctly. This type of issue may indicate a potential problem with the grid connection itself, such as fluctuations in voltage or frequency, poor wiring, or an unstable grid supply. It could also be caused by external factors like loose connections, faulty breakers, or grid protection triggering due to irregularities. We recommend checking the physical wiring, grid stability, and any external protection devices to ensure they are operating as expected." Only logging a faults normally takes longer than a day to get feedback.

Hi Bobster I'm very impressed with your diagnosis. Thank you. The Electrician left a few minutes ago, the neutral wire in the main DB somehow "worked" itself loose and after tightening all connections all is well. Goodwe support made a similar suggestion. I learnt a couple of things One should at least once a year have an electrician check your systems and DB's The house only used 40% of the 14.2kWh battery capacity overnight from around 16h00 to 07h00 If there is enough sun batteries are fully charged by 13h00.

Thanks Bobster I made a screenprint of SOLARGO, it looks like the ES is not seeing the grid at all, the Alarm field is blank. Logged a problem on the Goodwe site

Hi Bobster Its in general mode. It started at 7:34 on Saturday morning and still going, I cant find any messages in Solargo about but grid voltage & frequency. There are settings to protect the inverter. Upper voltage 269v, Lower voltage 171, Upper frequency 52.45Hz, lower frequency 47.55Hz. In Advanced settings Power limit value = On, Power Limit value set at 6000. On home page Meter/CT status Not detected. Backup ON, Power limit ON

My 5+ year old inverter suddenly does not "see" the grid, I did not change any settings, although did try to look via SOLARGO if I there were any settings that could have caused the problem, turned export limit on and off, think its turned back on, the oven on non-essential also does not work. If I turn off the inverter of and move the changeover switch to MAINS i can power the house and oven but the moment the inverter is connected the grid dissapears. I'm normally able to push power back into the grid. Has anyone had a similar problem and can suggest a fix? I checked with a friend if there were any grid instabilites high/low voltage frequency changes but he did not record anything excessive. I see there is a reset pinhole on the smart meter (where power is fed into the house) but did not want to fiddle with it.

Thanks Cef, installed without a problem it looks great and the weather widget works fine. I need more time work with the utility for the momen the focus is to see how best to extract the data (the dark background and figures makes it difficult to read), the 3D bars and legend seems the clearest for hourly data. Thanks again, its of great asssitance.

Thanks Cef Looks great, where do I get version 4.6? I'm still running 4.02

Thanks for the reply Cef There is an off grid option in the JRC Photovoltaic Geographical Information System (PVGIS) - European Commission, to provide a more accurate estimation of power not utilised and battery utilisation, % days with a full battery or % days with a depleted battery. One you can feed in the % power use per hour for a average day (24 hours). This will allow you to determine extra PV/battery capacity needed to go off grid. I would extract sample data sets for a couple of scenarios The consumption data in the GR tab per hour is what I'm after, to access the data per hour it looks like I have to hover the mouse over the hour and write down the values. Is there a way to directly access the data displayed in the GR tab for a day? Thanks

Hi Cef I've changed routers and can again access you utility. I'm trying to do homework on going off grid, it appears one needs information on your useage pattern throughout the day, probably on an hourly basis. I've extracted the data in exported CSV file but the volume of data is intimidating about 90k records for a day and 65 for a minute, is there a way to aggregate the data per hour?

Firmware updated but same error message. Assume its the LTE router but not getting support. Also a torrent site where the incoming connections time out so it may well be some communication problem.

Thanks CEF i dont have a password, will ask them on monday.

1252519 I did not request a upgrade of firmware, unless done by Goodwe, I suspect some issue with the new router

Hi Cef In January 2025 I change my Router and thereafter was unable to load your Goodwe app V.04.02. I get this error message below. I found the inverters IP adress using SEMS+, network link, WLAN. The ping command is returning data but I'm still unable to obtain access the App. Any suggestions on what else I could try? I'm not as technically savvy as PilgrimToHyperion..
