3x QB120 on a HLG-150H-48A

So, I made a diy QB120 setup with 3 boards running, on the HLG-150-48A.
I was scoping the suggestion configurations for parllel wiring and it struck confusion.
Should I not wire 3 qb120's on the HLG-150-48A?
In other words how would I got about doing so? I currently only have two boards wired in.

Those QB120s are 24V boards so if you’re running them in parallel right now on that driver, they’re getting too much power. You would have to wire them in series on that driver to keep the current reasonable. 3 boards won’t work very well on that driver and may put the driver into hiccup mode protection.

This is them running in parallel
I did try wiring them in seris prior to parallel
But the lights wouldn't turn on, what if I run them like this but have the voltage at 50% using the built in dimmer, still open to rewiring and double checking though

Unfortunately the driver and number and type of boards you are attempting to run do not work well together. An HLG-150H-24A would have been the right match for wiring all three boards in parallel.

Best option with what you have may be to wire 2 of the boards to the driver in series.

Driver would give up to 76.8 watts per board which is just above the qb120's suggested max without heatsinking, but may be okay, or turn it down a bit from max. Won't be as much efficacy as 3 boards on the correct driver, but it would work.
