Elite 200 V2 on Generator

Product Discussion BLUETTI Elite & EB Series

Hello all

I am off grid up in the mountains.

Yesterday I purchased a generator. I don’t know if it’s pure sine wave or not.

If I connect it then I get a warning that the frequency is out of range. The Elite is telling me it is supplying at 55 Hz and won’t take a charge. The advanced settings don’t seem to let me change the limit to above 53.5 Hz.

If I reconfigure the Elite to supply AC at 60Hz then it accepts the generator input and charges OK. However, I can’t have my 50Hz equipment (Starlink, PC, firewall) connected at that frequence which is proving inconvenient to say the least.

Do I need to take this generator back to the shop?

TIA
Andrew

Rocky mountains or Swiss Alps?

Hi Andrew,

Thank you for reaching out! To help resolve the frequency issue, please try enabling the grid adaptive mode on your Elite device. This might help it better accommodate the generator’s output.

Additionally, could you provide the device’s serial number and firmware version? This information will assist us in troubleshooting further.

Looking forward to your response!

Neither, but the Alps are on the agenda. Sierra Nevada in Spain. Maybe I should have said hills.

Today it seems to be working with the generator at 52.9 Hz. I had adaptive grid enabled and even throttled the maximum current draw.

Maybe the generator, being brand new, needed to settle in.

I’ll keep an eye on it.

Thanks for the replies.

Well, my optimism was short lived. After about 45 minutes it stopped charging. The generator output was at 54Hz and that proved to be too high for when I set the Elite output frequency to 50Hz but too low if I set the output to 60Hz.

Extending the over-frequency tolerance from 1 to 10 seconds got it working for a while but then it refused to take any charge at 55Hz. Seems a load on the generator tends to lower the frequency slightly but once it rises above the 53.5 maximum in the Elite settings it stops charging.

I suppose I have three options :

  • Find a way for the Elite to be more tolerant

  • Find way for the generator to output closer to 50Hz

  • Return the generator and look for another.

I’d rather not do option three as the store is a long distance and I’d have to box it back up and no doubt argue the case for a refund.

Any help appreciated.

Thanks
Andrew
