If a solax triple hv battery is down at 30v can it be recovered

Depends. If the sum of the cells = 30V, not a good sign.
If the BMS is in protection mode and reporting an arbitrary but low voltage, AND the individual cells are above about 2.7V, then it's worth trying.

Then I would assume that's a BMS reported value. if this is a 48V battery, 30V is well below any meaningful operating voltage.
Has anyone tried charging it?

Is it a 16S (51V) battery or a 32S (102V) battery?
If it's a 16S battery, there is great chance that you can recover it.

Maybe... It's the only answer because you will need to dismantle the batteries and test each cells to find any valuable capacity.
Let say you find many cells at 0V, but some other are at 2V or 3V, you can potentially recover those cells and build a new battery.
But clearly, if your batteries are 100.8V nominal as imply the spec sheet for the Solax Triple Power T45 HV, there is huge chance that all those cells are dead.
Maybe start to try to measure the voltage of a single cells. And add pictures, that will help us to help you.
