No load Quattro 48/5000/70 consuming ~ 50W

Hello everyone. I am still new to solar here. I have a battery built and do not have the Quattro hooked up to PV array yet. I have an MPPT 250/100 as well as a Cerbo GX hooked up.


I feel like this is a pretty large drain while in inverter mode can anyone confirm this is normal? When switching to charger only mode the draw is sugnificantly less at ~5W

Hi northtown2022,
Yes, this is normal. To keep the Inverter working some energy is needed..
This is also explained in the manuals.

Regards, Rob

The specified no load draw is quoted at 30W I believe.

Yes but there are also other components to add there. The mppt, gx and whatever else is in the system.

The Mppt and Cerbo draw <5W. This screen shot shows 44w but also reports 49W. An addituonal 15W loss is likely not that significant. It is just unfortunite it wasn't the other direction :)

This has been discussed at length in previous posts and if my memory serves me correctly the no load DC current draw can very quite a few percent between various builds of the same model Quattro. This load decreases if in AES mode or in search mode but those modes have their own interesting attributes to consider.

Three phase system 3 x Quattro 48/10000 - around 360 W - what to say.
