Growatt 48v SPF3000TL LVM-ES, change low DC recovery voltage?

[sinkillerj]

I'm currently running a Growatt 48v SPF3000TL LVM-ES with my low DC cutoff voltage set to 46v, this is working well, however the inverter turns back on at 50v. Am I missing some way to customize this 50v recovery voltage, or am I doomed to rely on external logic?

Of note: This is a purely off grid system, solar and battery only, the AC input is not being utilized.
