On Wednesday I received my new solar kit, the BLUETTI 2AC300 + 4B300 + 1P030A + 6PV200 kit (less the P030A). I’ve been testing the AC300’s separately paired with 2 B300’s each. The first unit is working as expected, I’m very happy with it. I put the second unit in my RV. It was working but now shows an error 008, Over Current Protection, anytime I try to use AC power, in or out. I have unplugged all loads, turned off all output power and rebooted, no joy. I haven’t received the Fusion box yet so it’s not related to that. I emailed support and got a response early Thursday morning asking for more information, which I provided. Nothing since. No one answers the phone and voicemail is full. I’m hoping to get an RMA soon.
@Rocketman
I have the same issue, 008 OCP, got my second AC300 today. Same error, only when grid is connected.
For example, i can leave the AC300 with grid only connected… after 2-3 hours the error comes up.
How did you contact the support? What did they tell you?
@chris, I kept emailing them and they replied yesterday with an RMA and a UPS return shipping label (they’re paying for the shipping, which is great). Once they receive the return they will ship me a new unit. Max has been helpful, just not very fast to respond. My second unit has been grid connected for a week and works perfectly.
Good luck!
They do not answer me…
Following! I received the 008 ocp alarm today. If I clear the alarm, it returns right away with out any input or output power.
The 008 OCP error appeared for me on Thursday. I reached out Thursday evening for assistance and for a possible RMA since that seems to be the only fix. I haven’t heard back yet.
Last time I reached out on another matter, Max responded pretty quickly and was very helpful.
I just bought a second B300 and 30amp charging cable neither of which I’ve been able to use yet since the system is unusable.
I had plans of expanding this system over time, but am hesitant at even buying a 2nd AC300 at this point until these things are worked out.
Hopefully they honor the warranty and replace it fast and can fix these issues through firmware.
As an aside, I’ve also had a lot of trouble with the WiFi module as many others have reported. Bluetooth has gotten me by, so I stuck it out in hopes a firmware or app update fixed the problem.
One of my AC300’s just started throwing a 008 OCP error, I can’t charge the batteries via the AC300 at all. Both of my AC300’s are grid connected, it just started for no reason. I submitted an email for support yesterday. I have not had a good response for other issues, so will see what they do. If anyone know’s how to fix it, please let me know.
I just got an 008 OCP problem this evening. I heard a pop like something tripped or snapped. After that, the ac300 blacked out and would not power up. Pressing the ac300 power button would try to power up the b300 and I see the b300 power button light up and then shuts off.
I know others have sent their units back via RMA from this issue. The unit this happened on is a new ac300 model from an RMA From Winnie. I had sent my original ac300 back because of the transfer switch issue. I had documented this issue by video and They wanted my unit sent back to them for analysis.
Last week I sent an email to Winnie asking for a status of the analysis and issue. This morning Winnie asked if the new ac300 solved the transfer switch issue. I had not tested the new ac300 with the transfer switch and went to test it. I unplugged grid power and replugged it to restore grid power then the pop happened and down it went.
Does Anyone have any more info on this problem? I am wondering how many ac300 OCP returns Bluetti has gotten? Has this issue been solved? Or do we keep sending them back? I am concerned when a new one is sent to me. Whether it could happen to that one as well.
Hi Everyone… I would like to know a little more about your issue and how your system was setup when this occurred. I have documented in a YouTube video an issue with Spike Startup Loads when starting some appliances/devices while the AC300 is in Split Phase Mode and Plugged into the grid for AC charging.
What I would like to know is when you experienced your issue, was your AC Input cord plugged in? And were you in split phase mode or not.
You can see my video here, in which Bluetti support is currently actively engaged with me on this issue: Bluetti AC300 - Split Phase Grid Pass-through spike startup load issue - YouTube
add me to this list! i just finished setting up my 2 ac300s in split. i have the fusion box connected to a reliance control a310 transfer switch. i was able to get every 120v circuit running, no problem. i have the 2 units connected to separate phased 20amp outlets with the max input on each unit set to 15a (note: i had to order a soft starter to hook up to my 240v air conditioner on the hope that this would work. - so havent tried that yet). anyway, today - one of my ac300 units shuts off with a Code #8 over current protection alarm and since then i cannot turn the inverter back on. the unit is still powered on and receives solar input, but i cannot output power.
You mentioned your ac300 had an 008 OCP and shutdown. Since then your inverter refused to turn on. Does that mean it shutdown and you were able to power it back up ? However ac output would not work? The inverter relay/circuit must have shorted and toast.
On my ac300, got 008 OCP shutdown and cannot even power back up. With mine, something more must have shorted affecting the circuit from powering up. I tried to plug it in to the grid again and power it back on and the outlet shorted with a loud noise (loud poof) and breaker cut the power. So the whole ac300 is bricked. Winnie asked for my serial number and will send me an RMA hopefully tomorrow.
Sorry you said shut off not shutdown. Did only the inverter shut off and the ac300 stayed up?
correct. the ac300 stayed on - just the inverter fails. i can turn on dc output just not ac output. and solar input works. when i try to input grid it goes back to the code 8 error alarm.
Add me to the list of AC300 failures. First one kept throwing voltage errors and shutting down. Second one was fine for about two weeks. Then it threw a voltage error accompanied by the very strong smell of burnt electronics. I’ve have not contacted Bluetti to exchange the second one yet. I am hoping they fix whatever is wrong and am hoping the next one will be OK. I’ll probably contact them this fall.
I received a response via email today. They are sending a new one (I’ll return the old one in the new box once it arrives). I hope the 008 OCP problem doesn’t occur again. But at least they are doing something about it.

Add me to the list. I had a licensed electrician instal a pro/Tran R310A transfer switch. I had previously asked Bluetti if this transfer switch was compatible since I read online that it would power your circuits but you would not be able to charge at the same time. Bluetti responded that I could use the transfer switch and there was no problem powering the circuits and charging at the same time.
They were wrong. When I hooked up the L14-30 cable I was able to switch to GEN and power the connected circuits, but the grid circuit the AC300 was plugged into immediately threw the breaker, so NO grid charging.
I posted a topic in the community and someone told me they fixed the problem by plugging the AC300 into a regular circuit that was not GFCI or AFCI. I checked, and the circuit the AC300 was plugged into was AFCI. I found a circuit that was NOT AFCI or GFCI but it was connected to the transfer switch. So, I set that circuit to LINE and left the others on GEN. When I plugged the AC300 into the outlet, there was a POP and now I have the 008 OCP(Over Current Protection)-Hardware alarm.
My solar panels just arrived today and my unit is completely unusable.
how long did you wait before they confirmed shipping a replacement to you? I’m over 48 hours with no response.
It was about four days. I suggest you put as much detail as possible in your request, if they need to ask another question, it will be another few days before you get a response.
Got my RMA from Winnie and will Ship my dead 008 OCP unit back in a few hours. Bluetti said the 008 OCP issue is fixed. Said make sure firmware is at the latest. They said the neutral from the grid and ac300 was not the same and they fixed it. I have another ac300 and they said make sure that one has the latest firmware and no need to exchange for another. I am still not 100% sure whether the fix is hardware or firmware or both.
Interesting… I’m confused though, if she said you don’t have to exchange the second unit, is that in regards to the neutral-fix or the 008-OCP problem?
