Several solar systems feeds

[wosjack]

Hello, it would be interesting to enter 2 or even 3 solar systems, for example

I know you can combine them via helpers, but this distorts everything.

Solar system 1 = But e.g. with me it is so I have a PV system that feeds directly this does not charge my battery or here I can not use the electricity either.
Solar system 2 = Then I have a PV system that feeds my battery
Solar system 3 = And I have a balcony power plant on the garden shed with its own battery

or can it already do that and I just can't find it?

You can fudge it a bit by setting some of the individual items as additional solar arrays or batteries, I've done that and it sort of works although the battery flow doesn't work properly bidirectionally

At some point I'd like to sort out the flow directions so it works properly for this configuration. This could then form the basis for adding multiple solar or batteries.

Ahh I see you have configured the GE2 Solar and GE2 Battery as 2 individual devices
Yes, the currents are not running quite right then

that's how i have the PV 1, which only feeds into the grid, displayed. i have entered it under fossil fuels and so it shows me that it goes directly into the grid and is not deducted.

Thank you

Yeah, it would be great to add more PV systems.
But space is limited. So what do you think about #670 and combine it with a detail view which appears if you tap on the Solar Icon?
This detail view could show the single values

that could work for multiple solar arrays, but for multiple batteries I think you'd still need to show them individually as one could be charging when one is discharging

[EckeFL]

Is that really a use case?
Normally batteries in one System should do the same. Otherwise you would shift energy from one battery to an other, which means you loose energy.
In my opinion, batteries should do the same or block changing/discharging while other batteries get charge/discharged.
The only scenario for shifting energy is, if you have a car and charge it from your home batteries.
For the car I use an Individual Icon

For me it is a use case. I have two inverters each with their own battery. The inverters don't know anything about each other so there is a risk of cross charging (although not particularly aggressive). Also you can have one inverter charging the battery from solar and the other not receiving as much solar so discharging to meet house load.

As I say, they are independent of each other. Generally it works OK but I like to see what each inverter and its battery is doing. At the moment I have two power flow cards, one for each inverter/solar/battery combo, but the house calculation is always wrong as the inverters share the load. Be nice to get it all on one power flow

Okay.
What do you think about the opportunity to set up multiple secondary entities?
The entities could be shown one by one in sequence.
