Evening, I have tried searching but I cant seem to find this particular answer.

As I understand it in my deyer inverter under system work mode I can set the maximum power discharge of the batteries for each time period I have configured. So if I set power to 4KW and my geyser comes on (I have my inverter set to zero export to CT) then the batteries will supply up to 4KW and the inverter will take anything extra from the grid. I observe this at the moment.

My question is, does this limit still apply during a grid outage and if so what happens when you hit it in the night (ie no PV power). I have the max discharge current in my battery setup set much higher than this.

What I am trying to achieve is to try not thrash my battery every night when the family showers, so minimise the battery power drain when there is grid power, but during load shedding I dont want someone to switch on the kettle and microwave and trip the inverter. Ideally if the time of use power setting only applies when there is grid power then that is perfect otherwise I may have to setup a solar assistant automation that adjusts these power settings when there is a power outage or load shedding

The time of use settings (including power limit) only apply while the grid is on. Once the grid power goes off, the battery charge/discharge current limits will apply.

I have 4 geysers on the essentials circuit of my deye 8kw inverter. They use wi-fi DB board timers to ensure they don't come on simultaneously.

For power outages, I have a home assistant automation that does the following-

If grid is off AND battery discharge is above a threshold for 5min AND battery state of charge is below 50% then I turn all geysers off and send myself a notification.

I very seldom have issues tripping the inverter by overload but it has happened so I'm planning to add an automation to turn geysers off if essentials circuit is drawing over 8 kW for a few seconds. Inverter seems to handle it for a bit and then overloads.

Cheers thats the exact information that I was after
