Lightly patched firmware version 71.80a for 5 kW PIP-5048MG, Axpert MKS II 5K-48 etc.
This is a beta version of the patched firmware version 71.80a, based on factory firmware version 71.80 for PIP-5048MG, Axpert MKS II 5K-48, and equivalents. It is not to be confused with factory firmware version 71.80 for PIP-5048MK and Axpert King. The only changes are that the two premature float bugs
are fixed, and the version number on the LC Display is different. If I did everything right, the main firmware version number should display as follows:
The two highlighted segments are supposed to indicate that this is the PIP-5048MG / Axpert MKS II
firmware, as opposed to the PIP-5048MK / Axpert King firmware with the same version number. Hopefuly this reduces confusion, rather than adding to it.
I do not own this inverter-charger model, so this firmware has not been tested apart from disassembling the patches. However, I did a similar patch to version 71.71, and this worked well (thanks, @ochyst
Factory firmware 71.80 has the same paralleling ID (118) as 71.70, so they should not complain about incompatible firmwares if paralleled. However, 71.80 does have 4 new CAN commands, all related to the new BMS functionality, so strictly speaking they should be regarded as incompatible. In other words, if you have paralleled and/or three phase machines, if you update one to 71.80 or 71.80a, it's a good idea to update all the others as well.
There is no LFP/non-LFP flavour for this lightly patched firmware.
