Can photovoltaic inverters convert low voltage to high voltage

What is the difference between high voltage and low voltage inverters?

A high voltage array can use smaller cross-section cables to connect it to the inverter, or can be sited further from the inverter, than a low voltage array. For 'reasonable' voltages, in the several 10s to several 100s range, there's not a lot of difference between the efficiency of commercial inverters.

Why do inverters have two input voltage options?

The third and most distinctive advantage is the higher efficiency of inverters at higher input voltages. If you see the datasheet of the inverters with two input voltage options they are more efficient in converting higher input voltage to mains voltage than converting lower input voltage to the same mains voltage.

Can a high voltage inverter hook up more than one panel?

Higher voltage does not mean that you could go as high as you want or you could hook as many panels as you have in series. You should look at the max input voltage rating of the inverter you are going to use and the max series voltage of the panels.

Is there a difference between a commercial inverter and a high voltage?

For 'reasonable' voltages, in the several 10s to several 100s range, there's not a lot of difference between the efficiency of commercial inverters. Comparably higher voltage is more preferable when given choice between different voltages.

Should I use a higher voltage if I have a copper inverter?

Going for a higher voltage saves money on copper up until you reach issues with cable insulation and/or max input voltage to the inverter. The "problem" is not so much on the inverter side as it is on the supply side. (Generally speaking, each inverter may have their own issues)

Does a high voltage array have a problem?

The "problem" is not so much on the inverter side as it is on the supply side. (Generally speaking, each inverter may have their own issues) A high voltage array can use smaller cross-section cables to connect it to the inverter, or can be sited further from the inverter, than a low voltage array.
