I’m experiencing an issue with my dual AIO when I’m exporting from the battery and I have high solar. It looks like when I’m exporting from the battery and I have high solar input into the gateway the Gateway completely resets. It looks to switch to battery mode and then back again. I’m also seeing that my settings are being overriden when this happens - I had Eco mode off so I can export all excess solar, when I discharge the battery with solar the gateway resets and when it comes online turns on Eco mode… Is there a away to fix this? With my single AIO installation, there was a frequency shift setting that needed activating.
assume you are talking to your installer and the Give Energy help desk?
You must be one of the first few to have dual AIO so I would expect them to monitor your set up closely in these early days of customer real operation s?
Hey Arfon,
I think the installers and givenergy might be your only definitive chance of getting a solve on this.
My first thought would be how the aios are chained.
Not necessarily power but maybe Comms from the gateway to the aios.
Whilst the aios themselves clearly have network connectivity.
Is the gateway not able to communicate to the batteries properly and inturn the battery’s are overloading the gw in high demand / export /generation scenarios.
Are you ethernet throughout your setup?
Do you have a Comms lead going from aio 1 gw out port to the to aio 2 gw in.
Thanks
Bob
Hi yah, I have a GW and 2 x AIO’s.
You have to think about what’s happening in reality (not necessarily what you would like to happen) if that makes sense.
Your system can import and export at 12000w (there is also a total limit of 18000w) but GE have set 12000w as default. You can message them to increase this but they will not go to the full 18000w I understand. They may go to 17000w max
Your PV system can do 5000w into the GW.
So if your doing the full PV 5000w and there is clipping plus both batteries at 6000w each that comes to 17000w (this is above the default 12000w setting). So the GW will have to do something to stop the excess.
If you also have a DNO restriction (check with your Installer as it will be on the DNO certificate, when they applied for the work). Then this could also cause the GW to have to do something. E.g if you have a 8000w DNO restriction then PV 5000w, the batteries should only export 1500w each.
In reality your system should look at all the situations and stop excess electricity going out to the grid. E.g full PV at 5000w your batteries will sit idle in Eco mode or should only export at only 3500w each.
P.S. I forget to add what I have done (in Home Assistant). I found my batteries discharged to quickly when set to the full 6000w each, plus the slots I have for charging did not require the full 12000w (6000w each AIO). One other thing to note is the GE system looks at the different % settings and moves them up or down to suit. So I wanted import 10000w and export 6000w, my setting has ended up at 9960w & 6000w, decided by 2 for each AIO.
As I wanted some battery incase of a grid outage I have set a 8% reserve.
