Hey everyone! I'm back with another question after receiving some great advice last time. I'm looking for recommendations on solar panels that stay under 12 amps. So far, I haven't come across any over 100 watts that fit this criteria. I have a BLUETTI AC300, and I want to add a rigid panel array to it. Right now, I'm hitting my amp limits without exceeding 100 watts per panel. I'm learning as I go and trying to figure out pricing and purchases. Any help would be appreciated! Thanks!

Most 100W "12V" panels are actually around 18V and usually only output about 5.5A. Have you checked if you’re wiring them in parallel when you should be mixing series and parallel connections? Also, ensure that you haven’t set your DC input to the car charging mode accidentally, which might cap your power even further. Keep in mind, the 2,400W max is the total limit, but the 12A limit applies per MC4 input pair, allowing for some flexibility with series wiring. Just be cautious of the VOC limit; not every combination will work!
I had the same initial thought! I’ve seen a lot of panels that exceed 12 amps too. I'm going for a series and parallel setup based on what I can manage for my array. I plan for each to come to the AC300 under 12 amps and 150V. Is there something specific about my combination I might be missing?
