Inverter input voltage question

[molibdimum]

Could someone please explain to me in layman terms what this means and how it affects the energy generated.

For example I've seen inverters with 90v - 500v range and some with 370v - 750v range.

Please go gentle because I'm a total newby.

They are specifying the DC input voltage range in which the device will operate. The higher the voltage input the more efficient the unit is.

I was told by one salesman that the inverters with the lower start voltage are the best because they begin to harvest energy earlier and dont require as much sunlight.

Is this baloney?

Pretty much so. Any good design of a system will operate near the high end of the voltage specification to minimize wire losses. Here in the USA a typical Grid Tied Inverter spec is 200 to 600 volts. In such case depending on location and how cold it gets the system will be designed to operate up around 500 volts.
