As in small remote power systems using multiple generators of different sizes matched to the load, does Victron plan a mechanism to dispatch different inverters based on the load? For example, run a 250/12 inverter for small loads and switch to a 3000/12 when larger loads occur.
I do not fully understand the existing parallel inverter control logic. Do they all go into AES/Search Mode in parallel, or is there a cascade based on load? If the latter, then that solves my question. If the former, then at some scale there is a rationale to being able to dispatch the inverters, just as one would dispatch multiple diesels to serve load.
I think its safe to say No.
why exactly would that be a good idea?
Not what OP alludes to but it would allow customer to buy small and expand systems. Something that's difficult unless you start with AC coupled PV route.
So scalability/initial cost is why it would be a nice idea for customers
(However I understand from technical stand point it's difficult to implement)
The "exactly" makes it feels so condescending hahaha
If OP means more from software/data point of view. Like a VRM data aggregator. Then i think that's also a nice idea. Feels less of a challenge as well
Ideal for marketing for installers. Easily see all the PV they've installed. Or for sites where there are multiple buildings with their own installs.
Hi @Diddikai
What you want will be true only if the zero-load power consumption between the inverters is considerable different. But the difference is too small in order to warrant developing what you suggested.
The smallest one is 5W for a 250W inverter and the biggest one is 20W for a 3000W inverter.
Just use the one that will satisfy safely your biggest load... It seems to be more efficient.

If yes, then problem is partially solved.
In contrast, if those small loads could be interrupted for a few seconds, maybe you can come up with an idea of switching between inverters with some relays.
Just some thoughts, maybe I am talking nonsense...

If 300Wh a day is an issue, then the extra expense of buying multiple inverters, wiring them etc would not be palatable, it would be cheaper to cater for the 300Wh in battery storage and PV.
There would be no interest in developing a system like that, physics aside, as it wouldn’t make any commercial sense.
"There would be no interest in developing a system like that, physics aside, as it wouldn’t make any commercial sense."
- I agree for OP's numbers it's not worth it but in general I disagree with your point.
You're running under the assumption that everything is bought on day 0. Not everyone can afford that.
A scalable system would be ideal for many. Not everyone is lucky enough to have sufficient funds to pay for a system that meets all their needs right now but would have sufficient funds to cover a portion. Building/expanding the system over a period of time would be useful for many.
My evidence for this would be the volume of posts on here of people having issues trying to parallel new multiplus with old in efforts to expand their systems....
However again I do understand physics is a key issue.
