Hi All,
For a week I have had brief and unexplained Overload L1 on VE.Bus System.
- In short, that is to say that about twenty seconds after the alarm is triggered, the system goes into CLEARED
- Unexplained because no change on my electrical network
- about 2 to 5 times per night and only at night
Any ideas?
Thanks for your help
you would need to look at your ac power usage graphs and make sure the gx devices resolution under vrm is at 1min resolutions. and then run for a while so the error shows a few times.
you need to track down if there are any motors starting or say two things running when it occurs
also a full description of what you have would also be helpfull
things that affect overload warning
inverter temperature
battery voltage under load
running loads and start up amps for AC motors
the batteries bms settings at the time ie its max allowed amps ie if the batteris voltage is low then the max amps that you are allowed to draw is also reduced, this does depend on what bms is being used and how its interfaced.
and how the bms is connected
Hi @Maa
This could be just a millisecond load spike. The ~20 seconds is how long the system takes to clear it.
I get this from a water pump starting when I have other loads on. I changed out the starter capacitor and that fixed it for a coupla years, but it's back again. Don't think I'll bother with it this time. And it never shows on any logging, except the email VRM sends.
