Solaropia SPI-B Solar Booster Pumps

Solaropia SPI-B Class represents a new generation of solar surface pumping systems that uses solar VFD technology to directly operate pumps up to 500 HP from Solar PV arrays.


High Efficiency-Lower Pumping Cost

Conventional solar inverters (Off and On Grid) are not suited to operate pumps – they would need four systems (Solar Inverter, Transformer, VFD, and Pump Controller) which translates into 20% of solar power looses. SPI eliminates all these systems (see the diagram below) and reduces solar system cost by average 40%-50%

Solaropia SPI-B Features

  • Operate pumps Off-Grid (in Rural Areas)
  • Operate 24 hours pumping in hybrid Solar-AC mode (in Urban Areas)
  • Pump type independent (no need to change existing pumps to use SPI solar power)
  • Models to pump up to 6000 GPM (1500 m3/h) at 450 psi
  • Advanced Industrial pump protection functions
  • Extremely efficient (about 40% higher efficiency than conventional solar systems)

SPI-B Applications

City Water Distribution Plant

SPI-B -500 model can pump 5 million GPD (20,000 m3/day) of fresh water using one solar pump at 500 KW PV


Brackish Water RO Plants

SPI-B 500 model can operate RO pump to deliver 1 million GPD (4,000 m3/day) from 3000 TDS brackish water using one solar pump at 300 KW-PV



SPI-B 100 can supply 1million gallon of water per a day with 100 KW PV to operate:

  • 200 MW power plant
  • 20,000 barrel oil production


Large Farms

SPI-B offers models to operate pumps to irrigate large farms up to 500 Acres with Central Pivots


Models and Capacities

SPI models are referenced following pumps horse power (HP). SPI is operated by PV array in KW equal to the HP of pumps. SPI-B models up to 500 HP are listed here for required pumping head (H) and flow rate (Q). Models are referenced with the required pumping HP (KW PV).
