Hi @GregP, Upon reviewing the video again, we noticed that the B300S battery’s charge level is at 0%, is that correct?
Therefore, we believe that this B300S has been over-discharged. Please disconnect it from the AC500 and charge the B300S separately.
If you are using solar panels to charge the B300S, please ensure that the total open-circuit voltage of the solar panels is between 12-60V. It is recommended to charge it for a while longer and confirm that it is fully charged before reconnecting it to the AC500.
@BLUETTI_CARE Yes, I’ve done all that multiple times. It’s obvious the B300S is faulty, after the upgrade for whatever reason. Just admit it is and repair or exchange the thing. You’ve cost my company over a £1000 by getting us to do heavily labour intensive tasks and repeating the testing we have already done. You’re now asking me to repeat that again. We’re just going round in circles with your stalling.
Start acting like a competent support system, although I only get one message from you a day!!!
Hi @GregP, We have been diligently investigating the issue.
We have noticed that Aurora is already assisting you with the warranty process. Please follow the instructions in her email to confirm the information and proceed with the next steps of the service.
Just as an update on my progress after 24 days since the issues were reported to Bluetti:
'The courier did not arrive Friday, as promised. When you get around to booking it again can you send us a copy of the confirmation from the courier as proof it has been booked.
Bluetti have consistently let our company down, and not failed to disappoint. It has now been 24 days since I first raised this service call and you haven’t even managed to pick up the B300S yet. Very amateur.
We won’t be buying Bluetti equipment again due to the disastrous service. I’ll be posting this on the forum.’
Has anyone else had problems with Bluetti service? They manage a message a day from the service centre!
Day 26, they’ve picked it up!
@BLUETTI_CARE It’s been 2months today since raising this call, I still don’t know when I’m getting a replacement. There is no urgency with your customer support. You should rename it @BLUETTI_NOCARE. The last email I received from ebayservice_uk@bluetti.com was 2/4/25. Your customer support is a joke and open to ridicule at its ineptitude. Who owns this issue? I need to talk to whoever it is. I need the contact details of a UK representative to escalate this to as the Chinese support is so poor.
Hi @GregP, We highly value your feedback and have conducted an internal investigation regarding this matter.
There have been some recent personnel changes in the eBay department, which caused delays in email responses. We’ve already reported this to the eBay sales manager, who will personally reach out to you—this should be completed within the next 24 hours.
In the meantime, we will also apply for your case to be prioritized. Please keep an eye on your inbox tomorrow for the follow-up email.
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.
