Axpert MKS II 5kW Main Firmware version 71.86.7z

By Coulomb

This is the main firmware version 71.86 for the Axpert MKS II 5K-48, also known as the PIP-5048MG and many other names. This inverter has a 450 V max solar charge controller, and does not have a removable display. It can be paralleled. Rated output is 5 kW and 5 kVA (PF1.0). Do not use this firmware with any other model. Not to be confused with the Axpert King firmware with the exact same version number!
