Meanwell PS as input to MPPT controller ??
Will it work? Will it break something? The Meanwell is rated at 500W, but I've seen it go up to 600-700W when the batteries are depleted. The EPSolar MPPT is rated at 520W PV input (and output for...

So far this seems to work ok.
In this first test, the batteries were not heavily depleted. Maybe 80-90% SOC? And initially the Meanwell was only putting 10A at 32.5V (the max V for this model).
That current rapidly dropped and when I finally figured out how the EPever Tracer display worked, it said it was in absorb mode (although it calls it "boost" for some reason) with ~29V at the batteries which was about right for the temperature and temperature correction and absorb voltage I had set (it's a 24V battery bank). The battery temperature agreed with that of my other mppt contoller's temperature probe.
The Tracer was set to 2 hours "boost", and when we came back from shopping it had moved down to float. So that seems to be working too.
So all is good so far.
To summarize: I now have two inputs to my EpSolar Tracer 20A MPPT solar controller: 340W of portable Solar panels and a 500-700W Meanwell Power supply. These two inputs are just wired in parallel as they will never be run simultaneously.
