Three phase Multiplus nominal / max power

Hi,

I read some messages with a Multiplus overloaded at lower power than nominal power.
I read documents from Victron with max power at 130% of nominal power (during 30min).

So I am looking for installation feedback to figure out what is the real capabilities.

What is the nominal/maximum power (for how long) you get from your three phase Multiplus system on DC supply ?

Thanks in advance for your feedback.

@Gabriel

Answer depends on operating conditions and temperatures.

See derating on temperature whitepapers.

And also was it installed correctly. I have seen many a good inverter crippled by a bad install. And of course power factor and load type.

We have seen a 10kva struggle/overload with a 1500w lawnmower because the lawmower did not have a good run capacitor.

Thank you @Alexandra for your reply.


Of course it depends on conditions and temperature.
Your document shows that Multi can provides 2 times the nominal power at 25°c like other documents.

This is a feedback that we can get very low output from a bad install.

What do you effectively get from a good install (for a given temperature, and time)?

Worth remembering that the 25C refers to internal temperature and not ambient.
