At sunset the Elite 200 V2 units relay keeps switching and clicking on/off for 10 minutes, 2x/day. It should wait for a higher power before restarting (or turning off) for a larger hysteresis. Any new firmware that solves this?
yes sorry PR200V2 is what is says in the app
Hi @jurgen, We indeed haven’t released new firmware for Premium 200 V2 to address this issue yet.
Could you please shoot a video demonstrating the problem, upload it to a cloud drive, and share the link with us?
Meanwhile, please provide the SN number and current firmware version of your Premium 200 V2. We will urge the R&D department to complete the corresponding firmware as soon as possible.
Thanks to @Selfmadestrom for his concern and reminder on this matter.

Hi @BLUETTI have the Elite 200 V2 with PV relay click problem at sunset and sunrise.
Can I have new firmware as well?

Hi my SN is PR200V22452000343107
I have not received the update as of today.
Still on IOT v8024.11

Hi @AndyR100, We haven’t developed a new firmware specifically for this issue yet.
Please disconnect the connection with the solar panel when the sunlight is insufficient. Hope this helps.
Hi @jurgen, We have consulted the technical department about this matter, and they informed us that the new function will be implemented in the app.
Please upgrade the app first.
Hi @AndyR100, I’m glad to tell you that we’ve just received notice that the new firmware has been successfully developed.
Now I have applied to upgrade your system to our IT department. They will push the latest version of firmware to your unit in 24 hours.
Please upgrade the firmware tomorrow. Please do not load any device when upgrading it.
Please let us know if it works.
Hi @jurgen, We would like to develop new firmware for Premium 200 V2. Could you please inform us of the current firmware version of your device, especially the ARM version?

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.
Both of my two Bluetti Elite 200 V2 solar generators, purchased this past July 2025 (Amazon Prime Day) have this same problem. Both are “up to date” firmware-wise. I would’ve thought that Bluetti would UNIVERSALLY solve this problem through its firmware, and not just for the one person who complained here.
Am I missing something? The problem manifests around 7:20 p.m. now, though that time will probably roll back as the season progresses and daylight changes accordingly. It does NOT occur in the morning.
I live in Soperton, Georgia, USA by the way.
Both V2s are powered by their own, two-panel, Canadian Solar 455W panels connected by a 100’ Temco, 8 AWG wire, and both otherwise perform as promised – on sunny days they reach 100% charge by 2:00 p.m. or thereabouts.
In the “Version” part of each V2’s app there is this data:
ARM v2172.14; DSP v2173.08; BMS v1068.11
One of my Elite 200 V2’s S/N is 200 V22523000324583
The other Elite 200 V2’s S/N is 200 V22523002015405
I’ve got them near each other, so it’s possible that only one is clicking, I can’t tell. But neither should by now, since I’m sure Bluetti wouldn’t let users suffer needlessly, correct?
By the way, my Bluetti AC200L, powered by the exact same panel and connected wire system and on the other side of the room, does NOT exhibit this problem.
Now the owner of three Bluettis powering critical loads, I just know that y’all want to make me happy here. I don’t want to find out that this is shortening the useful life of these V2s. Is it? One A.I. bot thinks it might. Please confirm. And again, since you’ve solved the problem for one customer, why not for all?

I got the elite 200v2 just b4 Christmas I am so getting the clicking relay morning and night is there any new firmware for my unit please.
Hi @Ktt, thank you for contacting us.
I have applied to upgrade your system to our IT department. They will complete the push within 24 hours.
Please upgrade the firmware tomorrow. Please do not load any device when upgrading it.
Please let us know if it works.

Hi @BLUETTI_CARE I have been keeping an eye on it for a couple of days now. It’s still clicking about 5 relay clicks morning and night.
Thanks

@Ktt Thank you for your attention and detailed feedback! The clicking sound of the relay activation you mentioned (occurring about 5 times each in the morning and evening) is actually a completely normal phenomenon.
Here is the detailed principle: Under the low-light conditions of dawn or dusk, the voltage will reach the charging activation threshold, but the solar energy at this time is insufficient to maintain stable charging. This will trigger a cyclic process:
As soon as charging starts, the voltage drops rapidly to the disconnection threshold, and the charging circuit is cut off immediately — corresponding to one clicking sound.
After the charging is cut off, the voltage rises slowly again to the activation threshold, and the circuit is reconnected — another clicking sound.
This repeated switching process is essentially the system making every effort to initiate charging. Once it detects that there is no available solar energy left, it will automatically stop this cycle.
This clicking sound is precisely a sign that it is attempting to charge, indicating that both the voltage detection and the relay operation mechanism are functioning exactly as designed.
If you have any other questions, please feel free to let us know!
