B300s best solar input

hi there, i have recently purchased an AC500 and B300s , i want to plug the b300s directly to solar , can u please tell me the best choise of solar with maximum input i can utilize?

i do search for 500w panels but the AMPs are more than 10, that the device can accept

is the ecoflow 400w a good option with 10.4Amps ? can u suggest better solar panels?

thanks
