AC500 firmware updates

Product Discussion BLUETTI Apex & AC Series
1

@BLUETTI_CARE. I have a pair of AC500 units that haven’t been updated in a while. When checking firmware with the App, the following updates show as available:

IoT 9041.02 > 9041.12
ARM 4044.04 > 4044.07
DSP 4045.04 > 4045.30

Surprisingly, one of the AC500s shows that it already has DSP = 4059.03 with no updates available. They both show the same IoT and ARM update availabilities. My question is: could you tell me what new features and/or bug fixes would result from upgrading both units to the latest revisions so I can decide whether or not to perform the upgrades? Both units are working and I’m not aware of any current issues with my AC500s but since there may be some new features with updating, I thought I’d ask. Thank you for your assistance.

Hi @TMan, thank you for getting in touch with us.
Please note that the latest IoT firmware for the AC500 optimizes unstable Wi-Fi connections.

The latest DSP firmware resolves the issue where solar charging power is limited when connected to AC loads.

The latest ARM firmware improves compatibility during generator charging and allows adjusting the maximum charging current via the app.

Your two AC500 units have different chips and version numbers, but both can be updated to the latest firmware with identical functions.

We recommend upgrading directly to the latest firmware, as it has been thoroughly tested to enhance the overall performance of the power station.
