More than one solar inverter

[losmedinilla-dav]

High-power inverters are expensive these days. So sometimes it's more economical to buy two smaller inverters.
The Sunsynk card is wonderful, but it doesn't allow two or more inverters to be connected in parallel. Let me explain: when they're in parallel, each one charges or discharges the battery similarly (but not exactly the same); they receive more or less energy from the strings; they receive different energy flows from the grid; or they send different energy flows to the load.

It would be fantastic if you could implement this functionality on the Sunsynk card.

Thank you.

I have an inverter with two strings and a battery in a workshop, a basic inverter on my roof and an inverter in a camper van (with solar and battery) plugged to the house. I simply show the house inverter as another string on the workshop and the van as another Sunsynk card...

Nice!
Would you be so kind and provide your code. I am trying to get a second inverter included without any success.

Not sure the YAML will help, none of the references will be correct, you won't have the images either. You will need a few custom cards too. I have overlaid two sunsynk power flow cards next to each other and put pictures on top of that, But you are welcome to the code.

I started with a horizontal stack card and created 2 separate power flow cards in it, on the right card I disabled all views for the grid...

Once that was working, I positioned them closer together and overlaid the other elements: an actual picture of my inverter,the van, the car and some extra stats.

There are quite a few Helper entities too that correct some of the values.

Thank you! It's different than I've expected - I had the impression, that you had been able to include 2 inverters into one flow.

[Tadpole48]

No, as per my original post, "...and the van as another Sunsynk card"
But it works well, especially as you can attach even more and if you wanted you can have different versions like full version on one and compact on the other, then just move them around a bit...
