Hi there, I have an issue with the cooling fans of my GW5048-ESA inverter. There have been a couple of very hot days in Madrid, where I live, and the fans in the inverter chassis just went off a couple of days ago, and they're quite noisy. The issue is that even though the temperatures as you can see in the dashboard below have ALREADY dropped (and you can see the history of the last couple of days), the fans will NOT stop. For the record I do have 2 batteries installed, that's why you can see both temps in the graph. This has happened to me the last 2 summers as well, and last summer I had the fans running for more than a week and they would not stop. Last 2 times it happened I ended up shutting down the inverter and the batteries and they would stop from running, but I don't want to do that EVERY TIME the temps rise. Shouldn't the fans stop automatically when the temps drop? In any case, it's been a couple of days since this started (please see in the chart how I have set some kind of threshold for the inverter temp at around 55C, and even though the last couple of days it was above that, you can see after that it would go down. I got tired yesterday and performed a total shutdown of the system in the afternoon to see if they would stop, but to my surprise they kept running!!!! This morning instead of that, with the inverter running, I simply restarted both batteries and the fans FINALLY STOPPED. Turns out in order to stop the fans, the batteries need to stop... but it's a fwcking pain having to unscrew the battery chassis and perform the reset EVERY TIME. Any ideas on what can I do to fix this? Thank you very much. Kind regards.

thanks, I'll keep looking into it!

Hmm, not sure I can set up a custom gateway in my DHCP server (Asus router). I can however set a custom DNS entry, and if I point it to a non-existent one it *should* do the same, shouldn't it?

I have had this happen at least 3 times that I can remember in the last 2 years. My inverter's FW version is 2525H as reported by PVMaster. I am not requesting anything, at least willingly... unless the inverter is actually constantly polling or whatever, but I don't know how to disable that behavior, other than putting a dummy DNS server as suggested by @Kalahari Meerkat...

In the 2 years I've had the inverter they have done this 3 times (that I can remember now). If there's a setting in the inverter to do that I don't know how to turn it off, do you?. Also as I mentioned tech support is useless (at least in Spain, where I'm from) since they respond late and don't seem to care. I had another issue (actually 2 times) in summer, when it was too hot, the fans would kick off and start blowing making a lot of noise, and even when the ambient temperature would drop in the evening, they kept running constantly... for an entire week... and I couldn't reach support, so the only actual option was for me to shut down the inverter and turn it on again, and magically the fans stopped working. Apparently the software is not smart enough to stop the fans when the temperature has dropped, go figure... My next inverter is definitely not going to be Goodwe. Thank you.

That is a very good idea indeed, but do you know how I could prevent Goodwe people from messing up with my inverter remotely?

Darn, you guys are right @VicB7 @Scorp007, some weird f*ck up with my dark theme settings (I'm using dark reader browser extension). 🙃 I have edited the text now so hopefully looks fine. Thanks for letting me know!

Hello there, I have a Goodwe GW5048-ESA model with 2 batteries and I'm not entirely happy with my purchase after a couple of years but will have to suffice for now. The issue I have is that whenever they decide to push a firmware update to my inverter, the system reboots itself, which leaves me without power for a few minutes until it all comes back. I have purchased a couple of UPS to connect some of my stuff, but I'd like to do something beyond that. It is annoying AF because they don't really let me know when they're doing it, and granted it's only happened 3 or 4 times, for me it is even more concerning knowing they can basically do whatever the f*ck they want whenever they want. And good luck reaching out for tech support, they care even less and their response rate is useless, probably they pay them crap, but that's not my problem as a customer. Anyway, is there a way to prevent Goodwe's technicians from accessing/rebooting my inverter remotely? Of course I'd still like to be able to read my stats, although I don't care much about SEMS portal since I've implemented my own solution: I can think of probably adding some blockages for outgoing URLs to prevent the inverter from communicating with the outside, but how can I block them from getting inside? Thoughts or ideas? Thank you. Kind regards.

The first screenshot is from the Grafana dashboard, but you can access the actual "application" I created, which shows something like this: Mobile friendly and such, definitely MUCH faster than PV Master... 😉

It's not a Windows app, it's a nodejs app + a web frontend + a couple of monitoring tools. 🙂 You only need to install Docker (https://www.docker.com) then clone the entire repo (https://github.com/gamosoft/goodwe-solarapp) where I posted the full source code and follow the instructions to have it up and running. Ideally you should have it installed in some kind of home server where it can be there 24x7 and accessible to anyone within your local network. This code is useful for just one inverter, and once you have it running it can be called from anywhere locally, just use the corresponding ip address or hostname. HTH.

Hi all, I have this inverter with a couple of batteries and been struggling with PVMaster and SEMS for a long time, I just don't like how they are implemented. 😞 I created this small app some time ago, that runs locally in your network to monitor it in realtime, just didn't have the time to polish and or publish till now. You can find all the code here: https://github.com/gamosoft/goodwe-solarapp Really, I would like Goodwe to provide better software and/or support, but I guess it is what it is, in the meantime I hope you enjoy this application and let me know if you find it useful. Kind regards.
