I have some very old 240watt panels that seem to max out at 200watts due do expected degradation. During a recent power outage I considered putting them in a 2p2s config to charge my power station. This puts me just over the power stations Isc rating (15.8/14A) and just about perfect for Voc (61.3/75V). I understand the overcurrent isn’t an issue. What I am curious about is if degradation shows up as less amps, less volts, or a little of each when supplying something like an inverter that doesn’t limit the panels output current?

My son does mobile detailing and wants the ability to fully power his vacuum/air compressor/pressure washer. He is looking at the Predator 3500 or 5000 ultra quiet generator for gas. I suggested he consider a large LFP battery setup. We have an Oupes Mega one that can handle the load fine but lacks capacity. It is really easy to add a 48v 100ah lap battery in parallel giving more than enough run time. Either path is in the $700 ballpark. What’s the best move here? Are there any gotchas I’m overlooking?
