I have an AC200P that I purchased in mid-2021. I contacted Bluetti support chat today and was surprised/disappointed to learn that no expansion batteries are compatible with it. The support person suggested an AC180 feeding AC power to the AC200P, which obviously isn’t ideal. Are there any other options possible for expanding the AC200P? It seems like I bought a year/generation too soon (or am seeking a battery expansion too late), which is really unfortunate.
Sorry, AC200P does not support expansion, can use B230/B300 for power bank mode.
But B230/B300 is now discontinued; you can check the second-hand market to see if any are still available.
