EP2000: High Grid Export while Battery not full

Hey everyone,

i have a problem with my EP2000 thats driving me crazy and i dont found a solution for it yet.
The custom working mode is enabled with SOC from 20% to 97%. Grid Feed In is enabled.

Expected behavior would be, that the battery would be charge until its reached 97%, feed all the power is needed to my house and the rest would be exportet to grid.

At the moment, the following happends (example):

  • Battery SOC: 59%
  • PV Income: 7kW
  • Consumption: 450W
  • Grid Export: 4kW

It doesnt make any sense for my, why 4 kW at this point went to the grid, when the battery isnt nearly full. Disable Feed in result in 3kW of Solar Power instead 7kW. It just cut the power that would be exported otherwise. I didnt found a specific trigger. I first assume the colder temperatures would be the problem, but now the battery have a temperature of 10 - 15 degrees celcuis which should be perfect.

Someone experience the same and have a fix for it?

Firmware is up to date:
IOT: v9052.24
HMI1: v6062.22
HMI2: v6063.05
ARM: v5032.18
DSP: v5030.18
Safety Module: v1076.05
BMU: v1075.05
BCU: v1074.11

Would be greaf if someone could have a look on it @BLUETTI_CARE @BLUETTI

Thanks

Please send us the serial number so we can remotely check the operating mode.
Thank you!

Send a DM. Thanks for your support :slight_smile:

Hello Erik,
You don’t happen to have a schedule with ‘Discharge’ active and ‘Feed Into Grid’ configured with 4kW at the same time, do you?
I only have the EP600, but with this configuration, the EP also exports for me, even though the SOC high limit has not yet been reached…

Hi @SigiKa

time of use is disabled, feed in is enabled. Even set it to “selfconsumption mode” doesnt change anything.

Thanks for your answer
Erik

OK, could have been…
On my EP600, changes to ‘Time of Use’ and ‘Energy Buying/Selling’ sometimes get ‘stuck’. I think I’ve configured everything correctly, but it doesn’t always get applied (?).
Sometimes the only thing that helps is a complete restart of the EP, then the settings are definitely applied. Of course, this could just be a quirk of the EP600. I’m always careful when I change something there, double-check everything and observe whether the behaviour of the EP matches my settings.
.
But I’m curious to hear what support has to say about your problem.

I already pull the EBOX Display and turn of the Battery Controller.

Temporarly fix at the moment is to set feed in limit to 100W and 1A per Phase to not waste as much i would to when i leave it at 5kw.

I will keep you updated
