April 18, 20242 yr Any one can help me to find firmware files for this inverter below MP5548-II Color: White Operating Temperature Range : -10 - 50°C 201013-0903440008 Inverter Mode Rated Power 5500VA/5500W DC Input: 48VDC, 131A Power Factor: 1 AC Output : 230VAC, 50Hz, 24A, 1Ф AC Charger Mode : AC Input : 230VAC, 50Hz, 42.8A, 1 Ф DC Output: 54VDC Max.80A, Default 30A AC Output: 230VAC, 50Hz, 24A, 1Ф Solar Charger Mode: Max. Power: 5500W Nominal operating voltage:360VDC Operating Voltage Range: 120-450VDC Max. Solar Voltage(VOC): 450VDC
April 18, 20242 yr It looks like it's a PowMr clone (possibly with a different label) of an Axpert MKS II 5 kVA with hacked firmware that overloads the output by 10% and the solar charger by 12.5%. Or more, I saw 90 A solar charge current in a PDF, but the label implies 110 A. The hardware is I think designed for 80 A. IF the firmware can be updated at all, it MIGHT work with Voltronic MKS II 5 kVA firmware, such as 71.86 (beware: not the Axpert King firmware with the same version number), but if it's working at all at present, I would not attempt it.

That one seems much like the first one, i.e. an Axpert MKS II clone, despite the name suggesting that it's a VM II (VM II has a smaller DSP and can't be paralleled). It might be by a different clone manufacturer though.

That one looks like it might be a genuine Axpert King II 6.2 kW, possibly a Twin model (two AC output ports). Indeed, when I scan the QR code, it says "Originally manufactured by Voltronic Power". Of course, the clones could copy that too 🤔

You can see the version of firmware attache. Many thanks
April 19, 20242 yr Wow. Those are both major firmware versions that I've never seen. I've added them to my What Axpert Firmware is That? page. So sorry, I can't help with updated firmwares in this case.
