About This File

This is patched firmware version 291.70, based on factory firmware version 91.70, for the Axpert MAX 11kW with a TMS320F28066 processor. It will display as 91.70 on the removable display, but as 291.70 via monitoring software.

WARNING! This firmware will not work if your inverter is the type with a TMS320F2809 DSP processor. Use only if you know that your processor is a '28066, e.g. if your main firmware from the factory was version 73.xx. If you get this wrong, the upload will refuse to work, but it should not brick your inverter (just restart).

The arena reflash tool is included.

This patched firmware fixes the premature float bug, and implements PV patches to prevent the panels from being dragged down below 200 V (was 90 V). This allows the battery to fully charge from solar, and increases PV production, especially in cloudy conditions.

For upload instructions, see https://forums.aeva.asn.au/viewtopic.php?p=87767#p87767 .

As always, use at your own risk.
