Multiplus II gx température / performance

Hi all,

I don’t understand why the multiplus 2 gx 24V/3000Watt in ess mode does not render the max convertion

For explanation here is today the dashboard :slight_smile:

Temp is between 20 and 25 degres but the inverter does not want to give more than 2514 - 671 = 1843

According to datasheet it must be a minimum of 2400 watt ?. Temps sensors are conencted to cerbogx

Some explaination ?

The Datasheet gives the max. power of 2400W up to 40°C Multiplus temperature, not ambient temperature.

You can’t really see the internal temperature, but I know from my system, that in a 25°C ambient temperature, the MP2 3000 can deliver approx. 2000W. It starts with 2450W and degrades after ~20min down to ~2000W.

You can use the temperature sensor, that is delivered with every Multiplus, and place in on top of the MP2 where the hot air is streaming out. Then you can better guess what is inside the MP2.

Regarding your screenshot, - the visualization maybe does not accurate/fast enough, that’s why it may not be that precise. I counted the Battery discharge current and the MPPT power what gives you approx. 2100W the MP2 is pulling…

Thanks jetlag

Interesting. I will move my second sensor on top of the mp2 to see and will adapt my fans according to the result.

Will come back to you later but thanks for the idear. perhaps i will move one of my extractor on top of the multi too.

And yes, a lot of nodered automation perhaps does not give me a realtime status…

Thanks

In addition, you can activate the visualization of the MP2 in VRM.

Therefore you go in remote console → settings → system setup → battery measurement → and select MP2 to be shown. Then you have this box below in VRM. this is showing you the output of the MP2.
