Machines start early

[requiemmg]

Hi again,

normally, machines used to atart when there was an excees power of x Watts. Now with my current setup and the current version, machines start when the solar production reaches value x, not regarding house consumption

Sorry for the bad formatting, that was from my cellphone... Not quite right what I said, just put my dishwasher to smartstart and solar production is at 1 kW, House consumption at about 1kW, machine is waiting. But yesterday's start was definitely too early and I'm not really sure why.

I'm back from vacation.

The verbose output of these four values is meant to debug cases like this. Inverter DC power = DC power coming into the inverter (production) Inverter AC power = AC power provided by the inverter (after conversion loss) Meter AC power = balance of production and consumption Battery power = battery charge (positive) or discharge (negative) rate

The inverter data is informative only and does not go into the decision when to start appliances.

The power export is computed as meter AC power + battery power so that appliances are prioritized higher than charging the battery.

Is the log from Jul 23 complete? These values don't appear plausible:

Inverter DC Power: 129 Inverter AC Power: 127 Meter AC Power: 805.00 Battery Power: 0.000000

Higher balance than production without a discharging battery?

Cant tell anymore, currently everything working fine. No idea. I will keep track of it.
