Multiplus inverting while grid is available

Not that I know of. Sorry :slight_smile:

Is this not the definition of loadshedding? :smile: Or did you already rule it out.

23

Oh yes, getting a 12 is exactly what you’d expect to get for load-shedding. But it seems he is also getting 8s (low voltage) at other times.

Possibly just some winter loads on his line (everybody in his neighbourhood on that line) and the line can’t handle it?

So I think I may know what this is.

My immediate next door neighbour complained on the neighborhood group that her electricity breaker on the street is tripping the whole time. They’re actually out of town, but the live-in domestic worker was turning it back on and then some time later it trips again. When my neighbour learner what was going on, they contacted the city and was asking advice on the group on how to escalate it.

This is probably the issue - close enough to me to briefly dip the supply voltage before their breaker trips and that is just enough to let my inverter disconnect from the grid.

Confirmed that this was indeed the issue - municipality was there on Wednesday night and then yesterday they had a private electrician come and fix the wiring into their house, and the issue is gone now!

Sjoe. Disturbing to see that a problem with a neighbour’s wiring can affect your system.

We are all connected. Even if you like it or not.

I remember a story someone told about an interview they had with a very successful mielie farmer. He consistantly had the best crops in the area and they wanted to know what his secret is.
The farmer explained that he figured out that his neighbour’s crops were fertilizing his farms plants. So to get the best crops he shared his best seeds with his neighbouring farms.

Glad they could fix it so fast :slight_smile:

@plonkster Do you happen to know what flag 64 stands for?

In the protection log? That’s 2^6, which is LostMultiPhaseLock. Don’t know exactly what it means, but sounds to me like a 3-phase systems where one of the phases is not healthy.

Great, thanks. This is indeed on a 3-phase system. I guess this means that one of the other two Multis has detected a protection condition and tells the remaining two to switch off.
