Prioritize exports first before charging #314

I don't think there are any inverter settings. I did it a while ago by setting the Forced Mode and Forced Discharge. Then when your rate changes, you can disable forced mode and the inverter will charge the battery. |

Your situation does not sound like it's the "PV is oversized compared to AC limit of the inverter" situation. You have 5 kWp installed on a 10 kW AC inverter?
With this setup, I can reliably harvest DC power >10 kW on my SH10RT (which has a 10 kW AC limit), as long as there's room in the battery to take the charge. Keep in mind: none of the above handles discharging the battery to the grid. The only way to do that is by using forced mode + forced discharge. You'll have to automate that externally (via HA, for example). |

I'm wondering what combination of settings can be used so that as the sun comes up in the morning my SH10RS will prioritize feeding all remaining battery and excess solar into the grid first, up until it maxes out my 5kw export pipe. Then maintain that 5kw export and begin putting any additional solar into charging the battery.
I'm wanting this so that I can make the most of the high morning feed-in tariff that I get via my direct market retailer (Amber in Australia), before the feed-in drops low again later in the morning once everyone else's solar has ramped up.
The common scenario here is that I wake up with a little bit of battery remaining, so I force discharge the rest of the battery asap to make the most of the high feed-in tariff. Once the battery runs out and stops discharging then excess solar continues being exported. But then my issue is that once that export hits my 5kw limit, the inverter will throttle the solar down if I still have it set in forced discharge mode. So I've been manually switching EMS modes each morning which is a pain in the arse.
Before I go ahead and try to do this with HA automations, is there some combination of inverter settings that will prioritize filling the export limit first, without throttling down solar production once it hits the limit?
