I just picked up a few of these panels used/cheap. They say there is a built in micro inverter and that they output AC, not DC. It looks to me like the micro inverter was removed before I got them(see schematic 2nd photo). I want DC output from the panel to charge a portable power station anyways. Just looking for validation that this is the case.
Also, I got the panels for $20/each. They are about 10-12 years old. The guy had about 5 more. Is it worth it to pick up more? I will be building some off grid structures(house and some farm buildings)in about a year. I'm sure I could use them somewhere, but I wonder if the technology has advanced so far in 10 years that something new would be much better.

I just got a few of these solar panels for cheap: AUO (BenQ) AC Unison PM240PA0. They were produced between 2012-2015 and apparently have a factory-integrated microinverter and output alternating current. The panels have standard MC4 connectors.
I would like to use one or two to charge an EcoFlow Delta 2. I will attach photos of the panel's specs and the Delta's as well. If it's not possible, how else can I use them?(yea, I'm a noob to all this)
Thanks in advance for any help/feedback.
