G’day Bluetti fans,
My AC300 decided to die and since the main board will not be available until late May (or so customer service stated to me) I decided to grab an APEX 300. I have changed my 2 x twin solar panels to parallel so that the voltage is under the 60v max and all works just fine.
I do have a question about once the sun sets. For about 15 to 20 minutes after the sun sets and it is still light out, the internal relays click on and off for the XT60 solar inputs. I have verified this is the culprit by disconnecting the XT60’s. The clicking goes away. Once plugged back in, the start clicking again. Not on/off - on/off but rather about every 15 to 20 seconds with the time getting further between clicks as the light dwindles.
This would put extra cycles on the relays, no? My AC 300 never did this. Is this normal? Should it be fixed by a software update? Or is there a setting I can change so that when the voltages get down it will just stop trying to charge?
Cheers in advance
Aussie
