Hello I have an AC 200 Max it seems to be acting a little strangely when I charge the device using mains then I turn it off then I turn it on later in the evening to use the device many times it will show me the state of charge as being very low such as 2%.
For example regardless of how many hours I charged it when I turn it back on sometimes it’ll show me the 2% and I know this is not accurate. I’ve tried to do a full charge to 100 percent At least once a week.
It doesn’t happen every time but it happens enough that I feel like it’s not acting normally. Because I have another one of these units and my other unit does not behave in this manner.
@BLUETTI_CARE Do you think a firmware or arm update could be beneficial in this situation? I’ve also noticed it happening in the other direction for example while charging I’ll reach 60% or 70%, and then suddenly it jumps up to 100%.
It seems kind of odd when I charge it for several hours off the mains and it’s showing me for example 65 or 75%, then when I turn the device back on it’s showing me only 2%, something is not adding up thank you
I’ll give some information about the most recent occurrence that happened. Last night I was using the device and it suddenly dropped to zero. I was a little surprised because what I had plugged in was only using about 150 to 200 W and the Machine dropped to zero after only a few hours. I was expecting it to give me at least a few more hours before it got low. I don’t like to keep the machine at zero so I charged it up to 25% and then I turned it off.
When I turn the machine on again later in the daytime it was showing me 0% state of charge. I knew this was not true. I plugged it into the mains for charging and after only approximately an hour and a half it went to 100% state of charge.
This doesn’t make sense to me because when I’m charging from the mains I get approximately 20 charge per hour. So one and a half hours would have brought it up by only 30%. I don’t see how it could have possibly reached 100% that quickly.
I appreciate any advice about how to proceed. If you think the bios or arm update would help I’d like to try. Otherwise if you advise I can send it in for repair replacement or control check, it’s still under warranty.
I like these products a lot. I purchased multiple ac200max units. I appreciate that you extended the warranties. I never regretted my purchases of your units. These devices have come in very useful during times of power interruptions. We have power interruptions in my neighborhood at least once a month. Scheduled maintenance interruptions can last several hours to a full day. Unexpected interruptions can last a few hours, or more or less. My longest unexpected Interruption lasted 12 hours and my shortest was a matter of minutes I used to have a lot of stress when this happened but thanks to your machines when we lose power my stress level is zero. Thank you.
