    ACS355 Solar pump inverter. Solar pump inverter overview The ACS355 solar pump inverter is a low voltage AC drive of 0.3 to 18.5 KW rating designed to operate with energy drawn from photovoltaic cells (PV). The inverter is customized to operate in dual supply mode, so the grid connected supply is used in the absence of energy from PV cells.

  • Page 17: I-V Characteristics

    Operating principle and hardware description 17  I-V characteristics Iact The I-V curve is not constant since intensity and temperature changes during day time. Under constant temperature, current changes linearly with intensity and voltage changes logarithmically with intensity. Since the voltage variation is small with respect to intensity changes, maximum power varies proportionally with intensity.
