I'm in the UK and have a ESS installation and it's great.
Unfortunately where we live we get occasional and very short power cuts, all between 1-5 seconds occurring about five times a year.
I'm not allowed to feed back to the grid during a power cut to protect anyone trying to repair what should be unpowered cables.
I realise I could switch to UPS mode but this would require changes to the consumer unit to add a controllable isolator to prevent back feed, I would rather not do this.
As the power cuts are so short, I was hoping I could enable a hybrid mode or perhaps change modes based on a status where the system acts as a UPS but after maybe 5 seconds it switches back to regular ESS and if there's no grid power it shuts itself down. This way anyone deployed to fix the network is protected and I cover over the short power cuts. If the cut is over 5 seconds it is likely more than just a blip and likely requires human intervention.
I'm sure that technically this is against the rules but I would make the DNO aware.
Any ideas how to enable this capability?
I assume it can be done in node-red but I was hoping it may be a feature I just haven't found yet?
My setup includes:-
Multiplus II 5000
Grid meter (between main isolator and rest of CU)
Cerbo GX
MPPT RS
Pylontech batteries
