Max System Voltage1,500 V DC

String Sizing & MPPT Safety Verification Tool

Calculates safe series string length based on extreme winter low and summer high ambient temperatures.

IEC 62548 Standard

Winter Record Low Temp (°C)Raises Voc (Risk of overvoltage)

Summer Peak Temp (°C)Lowers Vmp (Risk of dropout)

Inverter Max DC Input (V)Usually 1000V or 1100V

Inverter Min MPPT Voltage (V)Usually 160V to 200V

Max Cold Voc per Module44.62 VAt -10°C ambient

Min Hot Vmp per Module28.67 VAt 70°C cell temperature

Recommended String Range7 – 22 PanelsPrevents winter overvoltage and summer MPPT dropout
