About this chapter

This chapter provides an overview, operation principle and hardware description of the
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. The inverter functions with the latest in technology
maximum power point tracking (MPPT) algorithm to derive maximum power from the PV
cells at any instant.
The inverter is specifically designed to meet the requirements of pump manufacturers and
the original equipment manufacturers (OEM). For more details of the solar pump inverter
features, see section


Control modes

The solar pump inverter operates in local control mode and in remote control mode
identical to the ordinary ACS355 drive.
•
Local control—interfaces through the panel.
•
Remote control—interfaces through external control signal. For the external control
through digital input, refer the
Program features, page 31.
