I encountered a short error when I connected a refrigerator to the station. The short error was displayed in different cases: at some point immediately upon connecting the refrigerator, and in another case the refrigerator worked for some time (maybe 5-10 minutes) and again the short circuit error.
I am not sure that the problem is in the station, since I also tried to connect a coffee maker with a consumption of 950 W for 15 minutes and the station coped perfectly. Or a month ago I also tried connecting another refrigerator and the station powered it for 2 hours without any problems.
I am not looking for advice on how to fix this error, because I have a short case only with one refrigerator. But I am wondering under what circumstances the EB70 shows a short? Should I worry that my refrigerator is faulty? (although it works fine from the outlet)
Hi @N1ck, Based on your description, the EB70 can handle a 950W coffee maker and another refrigerator, but not this specific refrigerator, which likely means that its power requirements exceed the EB70’s output power.
Could you provide the exact specifications or a link for this refrigerator? We’ll help you verify this further.
Additionally, try removing all loads, restarting, and then reconnecting the refrigerator to see if that helps.
Thanks for the quick response.
I apologize for the long response, I dealt with this issue as best I could.
You got the situation right. But shouldn’t the OVERLOAD error appear when the power limit is exceeded? I’ve encountered the power overload error, but with the refrigerator I see the SHORT error, and I decided to ask about it here, because if I understand correctly, it’s a short circuit, which is a bit scary. Fridge: Atlant xm-6021-080
With a non-professional device, I measured that at peak the refrigerator consumed ~920W (most likely this is a short pulse at startup), and then ~150W during operation (measurements were taken from the home grid). Perhaps at the very peak the consumption was even more than 920W and then it is clear that EB70 will not cope. But I still do not understand why this is a SHORT error and not an OVERLOAD.
I have 2 household fridges, 1 is the big home fridge (540lt), it is an inverter fridge and a well known Japanese brand. (Aircraft, cars and whitegoods etc). The other is a 90lt AC bar fridge of a brand I had never heard of (A cheapy). It’s power draw is half that of the big fridge.
I used my AC180 on the big fridge, no issue and it will run it for near 12 hours. I plugged the small cheap fridge in to it (one fridge at a time, not together). It ran for 5 seconds then cut out with the AC180 AC switching off.
I therefore know the AC180 has no problem as it also runs other devices with no issue. My conclusion, the cheap small fridge did not like the slightly lower voltage of the power bank compared to the grid.
My grid V is 240VAC, the AC180 is around 230VAC no load and nearer 220VAC under a heavy load.
I would suggest you try a different fridge, like I did, that might tell a story.
Hi @N1ck, Thank you for providing this information.
We tried searching for your refrigerator model, but it appears that this model is no longer available on its official website, so we couldn’t find the exact specifications. Could you please take a photo of the nameplate label on your refrigerator? This will help us investigate further.
We consider that this refrigerator may be triggering the short-circuit protection on the unit. It would be best to check the specific error code when the issue occurs.
By the way, please note that if you need my assistance, please @BLUETTI_CARE, otherwise, I might not see your message and be able to help you promptly.
Thanks to @Mandp for the analysis and insights, we also believe that this likely isn’t an issue with the EB70, as it’s able to power other devices normally.
Overall, I think my thoughts were confirmed and the problem is in the refrigerator: it is too old for modern technology. EB70 itself works great and powers even more powerful devices. I think the issue can be considered closed.
Process of elimination is often overlooked. The moment I found my El Cheapo not playing the game from my AC180, the logical thing to do was try other devices, which I did. This proved the AC180 was not the problem.
