Save the R5000+ for the MPPT and control system from geyserwise and use it on panels.

On Inifi/Axpert inverters I would not run the MPPT at more than 75% its rated voltage.  For sure Voltronic Power are at fault for over-representing their product specifications and expecting the installer to use common engineering principles of 10-20% margin.  They likely have little to no margin on their ratings.

You specifically mean voltage or meant power? I have 2x 6.5KW strings (total 13KW) on my 10KW Infini, but each string outputs 530v, which is pretty much in the middle of the MPPT voltage range, however, I've definitely pushed the total power to near limit (15KW) of the inverter, should I be worried? One thing I've noticed so far is that inverter fans get quite loud now and solar assistant is showing internal temp or 61c during peak hours.

Only "mod" I did was to remove the fan filters and I clean with compresses air once a year roughly. 

Did removing fan filters made the unit quieter? Our has been running non-stop for 6-years and after recent PV upgrade to 13KW, the unit is screaming during peak hours. Would cleaning it with compressed air quieten the unit or is it just the way its designed?
