Read: How to Monitor Voltronic Inverters and UPS via WiFi →The Axpert MAX IND 6600 is rated 6600VA/6600W continuous, with 13200VA available on surge for the second a motor or a compressor starts. Size the load you actually intend to run against the continuous figure, never against the surge one.
The Axpert MAX IND 6600 takes up to 15000W (7500W x 2) of PV array. The tracker works over 90-450 VDC, so wire the modules to land inside that window.
Peak efficiency is 92%. Whatever is not converted leaves as heat, so the Axpert MAX IND 6600 needs clear air around it and a mounting spot that is not the hottest wall in the building.
