Minimum amount of 400W panels to connect to 1 string of a Powerwall Plus

[Astur]

I contracted a system with 16 400W panels connected (no micro-inverters or optimizers) to a Powerwall Plus.

Its my understanding that the the Tesla inverter has inputs for 4 strings, so I would like to connect say 4 panels per string.

I'm a true novice at this so hence me question and doubts. My amateur logic makes me think that 4 strings at 4 panels per string would be ideal and optimize production given any partial panel shading or failure.

BTW and should it bear relevance:
I live in Puerto Rico (18 degree Latitude), year round day time ambient temperatures mid 70's to high 90's, ample rain to clean the panels, very little contamination and no real all day overcast days. All 16 panels will face South and any nearby of affecting shade is not an issue.

Powerwall+ minimum string voltage is 60V. 400W panel at MPP is probably around 35V. So at least two panels per string.

Exactly what I needed, thanks.

I got one string with 4 panels. Do ask for four separate homeruns, they will want to combine homeruns or just use two mppt’s. One orientation, or four?

Thanks! Will do.
