While browsing through my recently installed 48/5000 Multiplus 2 (230V50hz) stats on VRM I noticed that the AC output frequency is low and out of spec.
The installation is a stand alone installation and the inverter supplies my home with power during grid power outages via a change over switch.
The output frequency is low from switch on with new and fully charged batteries, through varying loads.
Has anyone had a similar issue.
This happens sometimes when there is a mixup in wiring somewhere.
Especially if there is a neutral issue. Or the inverter is feeding back into itself somehow.
More info is needed here. The multi plus looks like its been outputting 50Hz fine
However if you connect to the mains or a generator the the unit will change to match the incoming frequency and then if its two low or high it will then disconnect from the mains/grid and start inverting again, please show the incoming vrm AC graph for the same time period,
Thank you for your replies and assistance. Herewith input verses output snapshot. Regards.
