Why am I getting Low Battery/overload light on the DMC?

So Everytime I use my air conditioner on battery (4x330ah lifepo4) I get a low battery/overload light for a split second when the compressor kicks in. Batteries show way above 13.5v

System has 2x 12/2000 multi in parallel so I can't see 50amps from the air con overloading it. Plus I'm using a soft start.

It doesn't happen when I'm on generator or shore power.

Anybody have advice on what's causing this?

Startup or inrush current of a compressor is much higher than normal draw.

You can look at inrush current limiters if it's a concern.

I thought that's what the soft start does? Also why wouldn't it happen on genset or shore power?
