Read: How to Monitor Voltronic Inverters and UPS via WiFi →The Axpert MKS 5 TWIN 6.5K takes up to 9000W 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.
Up to 120 A. Size the cable and the protection between the unit and the bank on that figure, not on the average you expect to see.
To 230 VAC ± 5%. That is the band the load actually sees, whatever the supply behind the unit is doing.
