Quattro 10 Kva overload whilst low load when power failure occurred

Hi,

I have a client whose 10 kVA Quattro switch off due to overload when the AC loads were very low (about 400 watts) and his batteries were fully charged with solar power available. What could have possibly caused this? This happened immediately after the grid was switched off by utility provider in SA due to loadshedding.

Many thanks,

Aldre

Hi Martin, with what you're describing nobody can give an answer.

please:

-describe the system (components?)

-measure / show what DC voltage and current does when you disconnect grid

-measure AC current when this happens

-everything else that might be relevant.

Hi @aldrevs

Did you find the cause yet?

If not the best way might be to contact your distributor for support, also if you can share the VRM id I can take a look for you.

overload can be due to a lot of things...
