First post, apologies if this has been discussed before though could not find one.
I have a 8500 Wp array with a Quattro 48/8000 and 19.2kWh storage battery.
I understand the inverter should be able to sustain130% of the inverter rated power, that is 1.3*6400=8320W for 30 minutes in my inverter.
However I never saw the inverter exceeding 6400W threshold. In the Summer, when panels were generating at peak of say 7000 to 8000W (with batteries almost full), the inverter seem to clip away the excess power.
Is there a specific settings that has effectively limited the Quattro not exceeding the rated power?
For a scheduled charging, is it possible to achieve such a high power for 30 minutes?
Hi. It’s unclear what you’re actually describing here.
What the Quattro can invert itself is it’s rating. In a DC-coupled system that’s the AC load applied. Nothing directly to do with panel output.
In an AC-coupled system (with a pv inverter) the Quattro can charge up to 110 Amps (check your model) into battery V, plus pass on AC (from pv) to loads.
Given your last line asks about charging, and that isn’t the same as inverting, you’d best clarify…
Hi John,
What I was trying to say was, when batteries are full, and load is low, and generation exceeds the 6400W threshold to say, 7800W, I could never get a grid export of 7000W. I know for a fact that the inverter performs with an efficiency of ca 91%, so I expected at least a 7800x*1%=7098W. But in reality I could never get an export of 6300W or so.
I was under the impression that the inverter should be able to sustain at least a 6400Wx130%=8320W but I never got this much export.
Export too, so more complex again. Not my field, maybe someone else can help. You’re going to need to supply a lot more info on your system I’m afraid.
