Read: How to Monitor Voltronic Inverters and UPS via WiFi →The Axpert WP TWIN 8K takes up to 8000W (4000W x 2) of PV array. The string has to stay below 500 VDC open-circuit — that ceiling is reached on a cold bright morning, not at noon.
Peak efficiency is 93%. Whatever is not converted leaves as heat, so the Axpert WP TWIN 8K needs clear air around it and a mounting spot that is not the hottest wall in the building.
Up to 150 A. Size the cable and the protection between the unit and the bank on that figure, not on the average you expect to see.
