anyone Xantrex Freedom XC 2000_12 Volt Inverter_Charger?

Hi all

Is anyone using the Xantrex 817-2080 Freedom XC 2000, 2000 Watt Pure Sine Wave 12 Volt Inverter - Charger?

How is it, generally? Likes? Dislikes?

It would be going into a new Hallmark Pop up truck camper.

I know that under heavy loads that the fans can turn on...

but under normal (light) loads (fridge running, solar panels in the sun) are the fans on?

and does it have any hum (acoustically) under light or heavy loads?

and are the fans 1 speed (on - off) or do they have different levels?

do the fans ramp up and down, or just switch on?

I don't like fan noise, or acoustic hum.... thus the questions.

thanks.

J.
