MultiPlus II in box

Hi,

my friend has a PV plant in operation with a Victron Energy system.

Three MultiPlus II 3000/48 inverters are installed, the connection is according to the picture.

Everything is in a closed metal box. Including 2x MPPT 150/100. Battery box 10 kWh is below.

Is this implementation ok?

Thanks.

It is going to get hot and derate.

Maybe add some forced ventilation.

I agree with Alexandra...

A fan as low as possible (say bottom right drawing in cool air) and another fan in the top left (taking the hot air out) forcing airflow around and over the units, this would help to keep them as cool as possible.

It's worse that the inverters are mounted sideways.

Very poor layout for inverters and the amount of power, should only be for 1x inverter in a vertical layout.!!!

Warranty could be void if i was a installer
