@BLUETTI_CARE …Hi, I emailed 2 days ago, no response,yet. Unit charging from third party Solar panels normally, it’s full Sun, then stops, shows zero Solar input for 20-40 minutes, starts charging from AC and then starts charging again from Solar……Software updated, setup to PV and high current , no error codes…does anyone has experienced this ?

Hi @JJDD, Could you please provide your service ticket number?
This issue can be resolved by updating the firmware.
Simply share your Apex 300’s SN code and current firmware version, and we’ll applied it for you.

Hello. Not sure if this is in any way related to your issue but I have some odd behavior on the Bluetti AC500 that sounds like it could be related to the issue you are experiencing with the Apex 300. Whenever I have had the solar panels hooked up to the Bluetti AC500 (variety of different panels including Bluetti and third party), I noticed that the reading of the PV input from the panel would suddenly go from reading an accurate input (ex. 330 watts) to showing 0 watts (same conditions - full sun and no clouds) and would stay there for two seconds or so before rebounding to the wattage it showed before. At first I thought it might be a loose connection somewhere between the panel and the AC500 but everything was confirmed to be secure. Then I realized that it was doing this on a pretty regular basis (timing varies every session) so the pattern lead me to believe it might have been a firmware issue. I have seen it happen in every charging session (using both the the DC1 leads and the DC2 leads). I upgraded the firmware with no resolution. It is worth noting that Bluetti seemed to be very helpful and had me actually send them my unit for them to look at but they told me they were not able to reproduce the issue. At my request, I got it shipped back to me so I am still experiencing the problem with both a B300 and a B300S battery. Just thought I would compare notes in case this was a related issue. Thanks.
Yes, similar issue, don’t know how long or how many times it happens, @BLUETTI_CARE told me they’re working on it thru the firmware , they told me to change the Working mode to “ Self-Consumption “ mode, so the battery doesn’t stay 100% charge at all times, but still does . This is my second unit, spent thousands on top Solar panels, installation and its problems and problems. Mostly wanted this as an UPS and in case of outage use, but it’s always something going on. It’s clear they don’t know whats going on , having so many issues and little answers. One time the ac button shut off and power stuff so my wifi, alarm , went out and I was on vacation. Wife mad why spend the money and so many problems
