For a while I have ben installing AC300 in the field and have no issues with them. Being discontinued our Bluetti rep has been selling up a APEX 300, saying it was the same just new. The problem I have is that I am able to connect 3 480W Qcells panels to the AC300 with no issues. I usually do two in series and one by itself. Since switching to the APEX 300, you cant connect two in series, it will cause the APEX 300 to error. The remedy is to connect them in parallel and 1 by itself. That seems ok to the customer but goes against their specs. The real issue I’m having and wanted to get the community to see if they have had the same issue. When we connected into the APEX 300 using the supplied XT60 connector the APEX will charge on that port. If i connect the second panel to the second XT60 power, I only see 48V but no incoming watts on port two, like it is only allowing for one port to charge at a time. If i remove the first port, the port that was not charging will start to charge. I’ve gone through ever setting, firmware, checked all cables, and tested panels. Any idea what the issue could be, or is it working as it should. Thanks all.
