I got a Growatt spf 3000tl lvm-24p can handle 80A on 24V - which is right around 2000W of MPPT
How much panels can I safely?
The local 450W panels which are cheap are right around 50V OCV and 40V MPPT - the maximum input of the Growatt is 145V - so to play it safe from the voltage I would need to limit it to 2 in series.
So I can do a 4x 450w in 2S2P - which gets me to 1800W
Or I do 2S3P which would be 2700W @ 80V - would be around 33A
