Power Grid Invereters

Off-Grid and Grid type inverters generate power for general use like any AC power. SPI generates power specifically for pumps to optimize power use and to control pump speed at the same time. It is an industrial solar inverter dedicated to power and control pumps more efficiently than conventional off-grid or grid type inverters.

Industrial pumps are currently powered and controlled using VFD (Variable frequency Drive) that are fed by three phase AC current to operate pumps in various speed. Off-grid and grid type inverters would require extra investment to add VFD to operate pumps. SPI already embeds solar VFD (S-VFD) that can be fed directly from Solar PVs to operate three phase pumps using solar power only (solar mode). It also can be fed, at the same time, from PVs and AC source (like diesel Generators or Utility grid) to operate in hybrid mode. It always gives solar power source higher priority as the main power and uses only portion of AC power source when solar radiation is low ( like cloudy weather), or to operate pumps at night time. SPI is about 30% more power efficient to operate pumps than conventional solar inverters (means require 30% less PVs).







Solaropia SPI Advantage

In Addition to power optimization, SPI demonstrates extra advantage over the two types of inverters:
