The lower wattage (<= 5000 watt) Quattro's recently (Dec 2022) had a firmware update to lower the minimum AC input current quiet drastically, but these higher wattage units were left out. I have this unit installed in an RV in the US and would love to be able to use a 120v 15 amp circuit on occasion, but with the minimum of 10.5 amps after the step up transformer is 21 120v amps. It's it possible to release a new firmware with a minimum of 6 amps for the input current when using Power Assist?
