WebUI and MQTT AC Total Limit

Describe the solution you'd like

It would be nice if the web interface could optionally display the Total Limit in addition to the Total Power. Example: 199.5W / 900W. 900W would be an example for e.g. three 300W inverters.

I would also appreciate if this value could be retrieved in the MQTT of the AC Total to display it in the Grafana monitoring without performing further mathematical operations here.

If you have two HM-800 with two 300W panels on each inverter.
Would you say, the Total Power should be 1200 (4x300) instead of 1600 (2x800)?

[EvilBlood]

In the first monet I would say that it is enough to sum up the configured power limits. I think if you would still take into account the DC power, you would still have to consider a lot about the self-consumption of the inverters and the conversion factor. This would miss the idea. I am only concerned with the sum of the configured AC limits.

@tbnobody I second this Feature request, as the current Power Limits should be summed up and shown next to the current total power. In case no power limit is set this will default to 100% or the total capacity of the inverters.

It is a good question if in your given example one would like to also calculate the installed maximum ?
So in your example when you have 100% Power Limit for both inverters:

Value	Inv1 / P1	Inv1 / P2	Inv2 / P1	Inv2 / P2	Total
Panel Wp	300	300	300	300	1200
Channel Wp	400	400	400	400	1600

Could be given as 195.1W / (Capacity Panels 1200 Wp / Channels 1600 Wp)

So in your example when you have 50% Power Limit for Inv1 and 75% for Inv2:

Value	Inv1 / P1	Inv1 / P2	Inv2 / P1	Inv2 / P2	Total
Panel Wp	300	300	300	300	1200
Channel Wp	200	200	300	300	1000

Could be given as 195.1W / (Capacity Panels 1200 Wp / Channels 1000 Wp)

That is the Channel Wp is limited by the Power Limit in % / absolut W.
Whereas the Channel Wp including the current Power Limit % does not limit the amount / Capacity that may be coming from the Panels in Wp physically / potentially.
