Hi, I’m looking for some performance figures for this Victron Isolation transformer (7000W 230V) that I didn’t find in its datasheet. Ads claim it uses ‘Toroidal wound technology for quietness and high efficiency,’ but I want to be realistic 
I assume its maximum capacity is 7000W, but what is its continuous operating capacity? What power output can we expect under normal operating conditions -at full power but without excessive temperatures or overloading the device-?
I would also like to know its typical transmission efficiency (95%? 98%?), how much energy is lost in the transformation, and too measurements of its sound noise levels in decibels (dB).
Thank you
