I am getting constant L1 overload alarms despite usage not being an issue. I have read the many docs and faqs that provide advice, however an alarm provides zero debug on where to investigate.
For example, an L1 overload alarm can be triggered by many things, more so with ESS, but when it happens you get no data from the subsystem that triggered the event.
This is a problem.
Hi Nick, yes it could/should be improved.
for your issue, I assume you found that you need to try with LOM disabled on the grid connected AC input on the Grid tab?
if there are no loads & your system is ESS, then thats what you have to do.
and if you can improve the wiring, do that. And if not, install external anti islanding device.
more details in the document you’ll have seen.
We have an iron running against a low base load. Every time the element kicks in (up to 2500w) it triggers an alarm. The power is first pulled from battery (up to 2100w) which makes no sense with a 1000w inverter limit and that we are on grid.
Why is it doing this?
Batteries are being drained despite being on grid and the alarms don’t give any data why.
This is a new install with new wiring, the gauge is higher than required.
The docs & possible issue I’m referring to doesnt relate to only your wiring, also the wiring between last mile transformer and your property.
This only started when ESS was enabled.
The alarms clear the moment they are created.
something is off.
Hi,
Have you at least tried that suggestion? I really advice to do that.
That (pointing to the doc and stipulating to try what it suggests) the best I can do for you here - for more official help, contact your dealer.
(or perhaps someone else here on Community can help you, that would be perfect as well ofcourse).
Best, Matthijs
I have changed modes to keep batteries charged and it is now behaving itself.
What i am describing should be obvious.
Something is wrong here.
Would appreciate some support instead of having me turn things off that the docs also advise you against.
This can be reproduced.
You can go through official channels too, but if no one can solve it then the official Victron answer will be the same: first update all firmware, and then turn LOM off. Even if only to know where the issue lies.
i really like to help, but so far I keep repeating myself and you simply refuse to do whats advised. I am sorry but I cant help further.
Did you get this issue resolved?
I have exactly the same issue with not very much help from our distributor. Also only happens in ESS.
Yes, I have discable LOM, Have changed grid codes, limited inverter power,
