@BLUETTI_CARE can you take a look at my message and reply/replies from others.
Thanks @BLUETTI_CARE I will keep an eye out the coming 12 hours for it. is this both for Relay and Fan issue? Or just Relay switching?
@BLUETTI_CARE can let me know when the update is available to install.
Also please advise if this is just for Relay or also Fan issue.
Will do! thank you. update: No DSP update to be seen.
Separate question: I have 2 solar arrays… I have one connected to the Ac200L. Can I connect the other to the B210 (its within Voltage and Amps spec). Or would this confuse the BMS or MPPT?
@ElDude You can connect the solar panel to the B210, but the solar input will not display on the screen of AC200L.
Understood!
Please double check on the Firmware DSP update. It does not show as update on the App, I am connected via bluetooth.
Hi @BLUETTI_CARE so I am on the app on my phone, connected via bluetooth. and I don’t see an update on the DSP. Or are you suggesting there is another way to check this.
SN200L2349000477638
or do you need to Communication board SN?
@BLUETTI_CARE so can not upload videos here! my Phone is a Samsung S24+. Attached pictures in lieu of my video.
It would have been more helpful if you had just told me the right procedure first.
As mentioned I got the app,
I do NOT click on AC200L, but rather the 3 dots of the AC200L device, then select Bluetooth to connect to AC200L
Click on the Gear Icon and the scroll to Upgrade - See if there are any! and click on BMS version to see if there are any upgrades there.
OPTION 2: When clicking on the 3 dots, rather than selecting BT, select Upgrade directly…
Both options lead to the same upgrade screen attached here.
I had the same issue and did not have the 200L connected via bluetooth. Are you sure your 200L and your phone are connected via bluetooth?
Hey Scott, yes! When you connect via WIFI (Cloud) and go to the upgrade section, it will not show the BMS and clickable “version” blue box. Connecting via bluetooth it will.
Also, I updated the 200L about 2,5 weeks ago, not possible connecting via Wifi.
@BLUETTI_CARE thank you now I do see the update. Will update today and let you know.
We still have pending the “Fan” topic.
@ElDude & @BLUETTI_CARE
I’m following this discussion. Did the update solve the relay clicking issue? I have a new 200L and a PV350. I haven’t connected the panel yet, but would rather apply any firmware fix now, rather than discovering the issue while boondocking.
@Bob70533457973917 Bob70533457973917 Bob, as it only occurs during sunrise and sunset (for the reasons many of posted), I haven’t been able to check on the reduction of the relay switching. Maybe this weekend I will sit next to it during sunset and see if the clicking has been reduced.
Honestly it is not a huge issue, my concern really is how many switches can the relay switch take before breaking down.
I will be looking for a solar switch to be able just to turn off/disconnect the solar charging myself.
