Read: How to Monitor Voltronic Inverters and UPS via WiFi →The Axpert MAX TRI 11K takes up to 12000W (6000W 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. The tracker works over 90 – 450 VDC, so wire the modules to land inside that window.
The Axpert MAX TRI 11K works with a 48 VDC bank. It charges at up to 40A/27A (MAX 60A), and that current — not the bank's capacity — is what the cabling and the fuse between bank and unit have to be sized for.
Peak efficiency is 93%. Whatever is not converted leaves as heat, so the Axpert MAX TRI 11K needs clear air around it and a mounting spot that is not the hottest wall in the building.
