Having suffered 6 hours of power loss yesterday, and a battery not fully charged, I quickly found myself without any power to keep my circuit on the EPS running. So, I am I right that if I set the battery discharge to power to 0 that does not limit what is provided to the EPS circuit?

I thinking of creating a simple script which drop the discharge power to zero when there is an extreme weather warning (via met office Datapoint service) and the battery level is less than 50%. This seems better than pausing the battery as it means the battery will still charge.

anotheruser yes if you set the battery discharge rate to zero the battery can only charge and not discharge to support the home demand

What I don’t know is whether the eps ignores the discharge rate if there’s a power cut. It would make sense if it did, but maybe you test it first to confirm

Don’t you have a reserve or minimum charge threshold?

Surely you just use HA to set to <higher than usual percentage> reserve for a met office amber warnings.

anotheruser I have been advised by my installer that if there is a power cut the house cannot access what is stored in the battery. We would either need direct leads from the battery/inverter or a much more expensive system to cope with a power cut.
