Portable Solar Panel // AC300+B300K

Hello Team Bluetti,

I’m looking (OK, wifey is insisting on her doomsday planning) for an effective/efficient yet affordable PORTABLE solar panel bank that I can match with the secondary DC input on my AC300 (DC2).

Suggestions?

I have tried Bluetti’s own PV200D, but returned it after being disappointed by the efficiency (<50W on a reasonably sunny afternoon)

We are London/UK-based.

TIA
