Hi,
We have a customer that's their Multiplus 2 occasionally(3 times in the last month) stops accepting the grid and then goes into overload and cuts out. Meaning they lose their emergency circuits, while the grid powered circuits stay on...the opposite of what we want.
When the overload takes place, there is not a lot of current being drawn through the inverter.
Has anyone experienced this?
Voltage and frequency input is normal.
Thanks Dean
Hi,
I have seen the same. Only happens at low loads.
Two things that are in the pipeline to be checked:
1) The distance from the street transformer is quite a distance, so it could be AC Ripples, to be tested.
2) The pre-paid meter is misbehaving, to be checked.
Client disconnected from the grid in the meantime, running inverter in an off-grid scenario unitl the above can be checked, ruled out.
Regards
Jaco
