I fear that my Growatt 48V SPF 3000TL LVM will not charge with my current 2 panels.

Panel # is a Solaria PowerXT- 370R-PD

and Panel #2 is a Newpowa 160W 12V panel:

This should yield 56.97 volts & 524watts. This is a little bit under Growatts 60V PV solar panel. So what might I do to make this work? I don't have the room for more panels.

Thanks for guiding a newbie.

So you do not have room if you replace panel # 2 with the same panel as panel #1?
 
Yes, Unfortunately, the case. I was limited to a 48-inch length. This NewPowa was the best option that also matched around 9.2 amps to maximize efficiency.
