6 x 8KVA Quattros on 3 Phase System

Good Day

As previously mentioned I have a system using 6 x 8KVA Quattros. 2 Inverters per Phase. The problem occurring is that once the mains power drops, the quattro's all seem to be limited to 8KVA.

The L2 Quattros overheat at 8KVA.

What could be causing this problem?


All Quattro's have latest firmware, all quattro's have the ESS assistant loaded.


The slave inverters seem to not be doing anything once the Mains/AC Inputs are gone.


Please help.

You really need to study this well.

This is not LEGO (no offence)...

Even the DC and AC cables must have the same diameter and should even have the same length!
Else the system wont run smoothly and problems can occur...

Sorry, not clear.

Do you mean when the grid drops the total output of the Quattros is 8KVA or are you getting 48KVA?

Some details on the batteries backing this up would help. As well as the ESS settings.
