Hi All, I’m new to solar so apologies for the upcoming stupid questions. My solar guy installed 9kw of panels (435w panels in the following orientations. 5 x east, 7 x South East, 9 x West), an AIO, GW, 5kw Hybrid Inverter, EV Charger and an Eddi. Max Solar generation has topped out at 4kw thus far due to the different orientations and shading on some panels. It was his first time doing an AIO but have seen he’s done loads on installs in the past and has all the GivEnergy training / certs. He applied for the G99 some time ago but the paperwork was not back before the install, i asked for the paperwork to register with Octopus for an export tariff when all this happened. The DNO has said that I can only export 7.36kw so G100 capped. From my understanding, the system is capped at 6kw at the GW for export anyway but not sure how to push this forwards now. Also not sure if the capacity should be measured at the panel level, the inverter, the AIO or the GW. Any advice would be much appreciated.
Hi,
Ive done a few installs with the AIO and hybrid inverters. You could potentially have 11kW (5kW Hybrid + 6kW AIO) that could go back to the grid, highly unlikely but the two inverters could technically push that out, if you’ve had a G100 export limit from DNO then i’d imagine your installer has set the AIO G100 setting to 2.36kW and left the hybrid at 5kW (7.36kW total). As long as this has been tested in commisioning and the DNO has had relevant paper work then there will be no issue with issuing your confirmation letter. Hope this helps

Thanks for the advice. Think the “Export to Grid Limit” is set at 7.36kw on the AIO so guess this has to be changed (it comes up on the cloud dashboard). Does the Hybrid Inverter also have this setting? As my average solar is about 4kw so 4kw + 3.36 will get me there and allow me to export more from the battery in the peak hours.
Thank you for your help thus far too, much appreciated.
Is your hybrid inverter a Givenergy product? As you’ve got a Gateway as well your g100 export setting might take into account the hybrid inveter if its Givenergy. Usually you cant set the setting any higher than 6 kW on a AIO standalone, might be worth giving the Givenergy tech support desk a ring to confirm or email them. But id imagine your installer has checked this already.
Thanks

Yeah, it’s the 5kw Gen3 Hybrid Inverter. Think GiveEnergy set it at 7.36kw for the installer. I thought that would take care of the entire output since everything will go through the Gateway. I tried to stick with one eco system (gutted that GE don’t do a solar diverter as that’s the only other kit). Think he needs to get here in the sun and give GE a ring as the chatbot is AWEFUL.
The export limit is set on the Gateway, so this should be set to 7.36. The inverter shouldn’t be able to output an extra 5kWh on top of this as it goes via the Gateway, so the Gateway is the one-stop shop for these settings.
Got on the phone with GE today, they had set the max export right but not turned the setting on in the GW. Turned on, restarted battery and now capping out at 7200w. Boom. Thank you got all your help.
