MultiPlus-II 48/6K5/100-50 230V efficiency curve

Hi Victron team
can you please provide the efficiency curve for the Multiplus-II 6k5 ( and 4k5 )

  1. AC–> DC
  2. DC –> AC
  3. temperature degradation

By the way , is this also available for :

Multi RS Solar 48/6000

And what about : Multi HS 19 , Multiplus-CL

I guess for the “classic” MultiPlus it will be almost the same as shown here:

Not sure if there is a similar curve available for the RS models.
The HS19 isn’t finished yet.

I have the same question

The new 4k5 and 6k5 has a new internal design and is more efficient and less noise according

I have a Multiplus II 48/3000 and I want to upgrade to a new Multiplus II

Hi Matthias,
thanks for sharing the curves for the well known 48/5000.
I knew this thread already, it is the reason for my question to ask for sharing the data of new models.

Background:
I’d like to optimise my system so I need to know the exact efficency.
Conneting panels by using

Microinverter and 230V AC

or Victron MPPT’s with 48V DC and then select which cable diameter ?
What is the best economic solution

Hi there, I’m also curious about the efficiency at low power levels for the new 4k5 model. Standby-loss at home is less than 100 W at night and most inverters have terrible efficiencies at low power. Growatt for example just makes me cry at low power.

Multiplus-II 48/5000 efficiency curve - VictronEnergy The DC-AC conversion at 200 W looks good following Raphael’s measurements for the old 5000 model. It would be great if the 4500 brings further improvements on the low end.
