I have new a MultiPlus-II 48/6K5/100-50 for an off-grid system and would like optionally connect a petrol generator during the winter periode to additional charging the batteries.
I have currently not installed the MultiPlus yet, but I have one question in advance:
How low can the minimum input current (A) be set?
At the moment we have a Honda EU20i with a max. of 2000 VA/230V.
That should be about 1600 W, so roughly 7 A at 230 V.
Can I connect this generator to the MP2 6K5?
Unfortunately, I havn’t found informations about min. input current in the datasheets so far.
There is plenty of information for how to configure a system in the various manuals.
It is worth doing the configure free training at professional.victronenergy.com.
You will need a mk3 adapter and the victron connect app or veconfigure to setup the unit.
If you have a gx and internet access, you can also use veconfigure and remotely send the configuration from VRM.
All these tools and features have manuals and are well documented. Just need to invest the time to search and read them.
A quick search would have found this (also many topics here on generators that can be searched for).
Thank you for your quick reply.
Unfortunately, I cannot find any data on this.
I am looking for the technical specification showing how far the input current can be reduced.
The app won’t let you reduce it below any minimums.
You would also use the dynamic current limiter, the link has all the advice you need to configure a genset.
Power assist restricts the input limit, but you didn’t mention that was enabled which makes it a little difficult to advise.
It is all in the manual which is always more reliable than any AI.
10.3.8. PowerAssist
Use PowerAssist to prevent an external AC input circuit breaker to trip due to excessive load. If the load exceeds the AC input current limit the Multi will start inverting in parallel with the external AC supply and will provide the extra current needed. Note: When PowerAssist is enabled there is a minimum AC input current limit depending on the device type. Setting a lower limit than this minimum will result in the minimum limit. Note that in a parallel system this limit is per device!
I wrote that the unit is already here, but has not been installed yet. I am still in the planning phase, trying to decide which of my current equipment and old PV system I can keep, and what I may need to replace or renew. That is why I am looking for the technical data that is still missing for me.
It is not easy to find all the documentation completely, read through it, and then work out within this huge amount of information what is actually relevant and what can be ignored.
In any case, thank you very much for the valuable tips.
Thanks

There is lots of free video training on there that will help demystify the ecosystem and provide valuable pointers.
It’s free and worth the time.
Thank you again for the tip. That is of course helpful.
I have just created the account, but even there it takes some time to go through everything and understand how it all fits together. I am also not completely new to the Victron world, as I have been running a 5 kVA off-grid system for 15 years, which I built myself. I have also already watched a great many Victron videos on YouTube.
That is exactly why I now tend to ask only very specific questions about certain information and technical data, especially since not everything is always included in the datasheet.
Everything is well documented but often in dedicated manuals, so to get the right information often means going through the inverter, VRM/VictronConnect/VEconfigure and ESS manuals, so a bit of reading and flicking between documents.
Then features often have their own docs like remote veconfigure and vebus updates.
So some digging around is often needed.
It’s why the AI’s struggle, much of the information is context dependent and the LLM’s just can’t figure out what applies where with consistent accuracy.
Peter created a FAQ topic in this section which addresses some common challenges.
It can be quite daunting to wade into the Victron Ecosystem.
