AC Input limit won’t go below 26.2A on a Cerbo GX

I have two Quattro 48/5000 running in parallel. For the AC Current Limit setting, editable on the Cerbo display, I can adjust it down but it just resets back to 26.2A when I press Accept.

Thoughts on what I’m doing wrong? Thanks!

Here’s a picture of the Quattro control panel. If i try setting it to 10a, for example, I get an error message.img-6255.png

If Power Assist is enabled, there is a certain minimum value for AC input current limit, dependig on the inverter model. Probably that's the cause.

Like seb71 said, the minimum input limit per inverter for your model is 13.4, you have 2 in parallel so it's doubled. (Yes I know the math doesn't add up exactly, it is an approximation.)
