IIRC the Redarc BCDC have a higher input voltage spec of 30 something and will run the higher voltage panels.
The Intervolt might work but they are a good manuf that is known for high quality bits of kit so will depend on the over-voltage protection and sensing.
We aren't in lockdown in Perth so maybe give them a call (08) 9331 8555 or info@intervolt.com and ask them if that panel will drop enough output when in circuit with their kit (the OC voltage is exactly that so "in circuit" it will drop depending on circuit load)
FWIW I used to use Intervolt programmable VSR's a lot before I retired from that mundane thing they call "work".
They were an outstanding piece of gear.
