asav reacted to Coulomb in BETA FIRMWARE AXPERT MAX 8 KW >>>MPPT improvement<<< (Based on stable 90.06)In this case, yes!
61.03 is already the latest in the available 61.xx firmware series. Presumably, that's why you patched to that already.
These are patched firmware versions x61.03 for the Axpert VM IV 5.6kW, 3.6kW, or 1.5kW, based on factory firmware version 61.03. Do not use with any other model, not even the later 6 kW and 4 kW models. This firmware attempts to work around the "stuck at 120 V" issue by implementing as many as possible of Georg594's original 90.06 patches. All patched versions fix the premature float patch (properly this time I hope), display a 5 digit firmware version from monitoring software. Use at your own risk.
Patched firmware version 261.03 sets the minimum MPPT voltage at 200V.
Patched firmware version 561.03 sets the minimum MPPT voltage at 150V.
Patched firmware version 861.03 does not implement any MPPT fixes, only fixes the premature float bug and the QVFW version number.
dsp_original_61.03 is the original unpatched factory firmware version 61.03, in case you want to revert for whatever reason.
