Install tip: Minimize system losses with proper inverter placement

By SPW This installation tip was provided by by Matthew Charles, senior applications engineer at Sungrow USA
The NEC requires that voltage drop within an electrical circuit (which equates to the loss the system incurs due to design choices) be no more than 5%. When it comes to fundamental PV system design, however, voltage drop is recommended to be less than 2% for both DC and AC circuits.
Minimizing system losses due to voltage drop ultimately comes down to inverter placement and conductor size, regardless of the DC and AC system voltages. String inverters are traditionally placed on the end of a row of
