I bought a new generator. The generator was set to wrong voltage setting 240 volt instead of 110 volts. Now both EP500Pros are failing to boot up. They just click relays and fail to boot up. They just “Boot Loop”. They boot up partially the shut off and attempt to boot up again, but don’t fully boot up.
Occasionally, they will boot up but they only stay running for a few minutes, they fail to take a charge or to discharge. Eventually they start “boot looping”.
There is an error on the EP500p’s that says:
006. SPS Voltage Low - Hardware
I have the latest firmware installed.
The App gives a different error message:
Error 007
Voltage Sensor failure
Bluetti Customer support says I am out of warranty.
I could easily replace the failing component by replacing the bad PCB board, but bluetti won’t sell individual parts.
Any thoughts on getting working without having to ship such heavy devices and wait for a paid repair? Additionally there are expensive shipping costs?
Hi @deez, Based on your description, you are using the low-voltage 110V version of the EP500PRO in Europe for 240V high-voltage AC charging—is that correct?
Please note that this usage is not compliant with the operating requirements. You will need to purchase a voltage converter or stick to DC charging only.
It seems that you have already contacted customer support. Could you please provide us with the ticket number so that we can investigate further? This does appear to be a hardware fault caused by excessive voltage. We will discuss whether there are any alternative solutions available.
I think @deez means he used a (Diesel/petrol) generator accidentally set to output 240 Volts in a 110 Volts country (USA) to a 110 Volts EP500Pro and probably fried some of the AC charging electronics in the process. (In this way you don’t have to travel to Europe with your 110 Volts EP500Pro to have this problem)
Hi @TheQuickFox, Thank you for your response, and you are right—this was indeed a misunderstanding on our part. Your reasoning makes a lot of sense.
However, the output of a gasoline generator is inherently unstable, and the overvoltage may cause even greater damage to the EP500PRO.
We do not sell spare parts, and we are concerned that there may be other internal components damaged as well. Simply replacing the PCB might not resolve the issue.
@TheQuickFox is correct. I use inverter style generator to charge up EP500P’s. I bought a larger INVERTER STYLE generator to charge two EP500P’s simultaneously instead of charging one at a time with smaller generator. The new generator came with the 110v/220v switch set to the 220v position. That caused bad result for EP500P units.
I hope you can arrange a good repair option with @BLUETTI_CARE for your units to bring them back to their former glory. Repair will have to be at your own cost because issues like these are outside of warranty coverage. If you need to ship the units, use the original packaging if you still have them. But a repair at your location would be ideal of course. However, I have not heard of Bluetti doing this often or at all.
And yes, those 110/220 switches are very tricky. I work as systems administrator and in the 1990s every PC power supply had such a switch. When someone would accidentally switch it to 110 (Here in Europe) it would result in a big bang. If you were lucky only the power supply was toast. If you were unlucky the whole PC was gone. Fortunately, this is a thing of the past and all PC power supplies auto sense and adjust to the proper settings.
@deez You could check if your home insurance or home contents insurance covers the costs of the repair.
Hi @deez, Thank you for getting back to us so quickly.
This issue indeed falls outside our warranty coverage. Please provide your email ticket number so we can further discuss potential solutions.
We greatly appreciate @TheQuickFox’s analysis—these insights are both comprehensive and highly professional.
