Max. PV Array Open Circuit Voltage (Voc) - Axpert 3KVA with PWM Charge Controller

I have a MPPT which has a max input voltage of 80V. This was supplied as part of a Geyserwise Dual system about 10 years ago. About that time they discontinued this MPPT and replaced it with a MPPT that can accept 130V from the PV panels.
This change was to be able to handle the higher PV voltages.
