Service manual with topology, description of each board, troubleshooting. Contains one or two simplified schematics.

Axpert King main firmware version 71.94. Use with recent removable display firmware such as version 02.49.

Fixes the problem of PV power dropping to zero when using the direct to BMS cable. Also seems to contain the fix in 71.93 for stopping AC charging when settings dictate.

Axpert King main firmware. File name originally included "No AC Force Charger". From Voltronic Power, not patched.

Main firmware for Axpert King 5 kW version 71.92. Use with remote panel firmware version 02.40 or later. This combination has support for several lithium batteries with BMS (including Pylontech, Weco, Soltaro, and Hubble via the Lib protocol). 

Axpert protocol manual describing commands such as QPIGS and their responses. Infinis and some odd Axpert models may not conform exactly to this document. Newer changes in blue and red.

Remote panel (display/MCU/BMS) firmware for Axpert King 5 kW. Use with main firmware version 71.92. It implements support for various lithium batteries with BMS.

This version adds two more BMS options (BAK and LIB) compared to 02.40. It also fixes a few bugs with the Lib Voltronic protocol and works with up to 16 batteries in parallel now.

Remote panel (display/MCU/BMS) firmware for Axpert King 5 kW. Use with main firmware version 71.92. It implements support for various lithium batteries with BMS.

This is now obsoleted by remote display firmware version 02.49.

This is the main (U1) firmware for the Axpert King. It seems to have better support for PylonTech batteries than 71.80 or earlier main firmware versions.
It came with Display firmware (U2) version 02.00; I now believe that it is important to install that first.
Do not use with clones, only with genuine Voltronic Power manufactured machines. Otherwise, fault F90 is likely after a couple of months of runtime.

Usually the firmware update archives (RAR or zip files) have instructions inside them on how to update. The Axpert King 71.86 main firmware does not, so I've added this install guide separately.
You may find this Axpert MKS installation instruction post of some help:

Infini-Solar3kW protocol manual. I don't know which models use this. It's an Axpert-like protocol, but with extra commands to access hybrid information.

Infini-Solar 5kW P17 protocol manual. This is an older protocol than protocol P18. Note how the length field (three digits after ^T) seems to be different to that of the P18 protocol.

RS232 command protocol P18 for the 5kW Infini-Solar inverter (MPP Hybrid V 5048). Quite different to the P17 protocol.

This is for 1-3 kVA 24 V Axpert/PIP models only. There are some schematics, PCB part numbers, part numbers, some measurements and troubleshooting.
I'm pretty sure I obtained this file from this forum some time ago.

Seems to be the protocol for RS232 over USB commands
