The AC coupled design takes advantage of the high efficiency grid-tied modules and avoids the complications associated with large DC based arrays using multiple charge controllers and additional wiring.

Although the pumping station is located miles from the utility grid, the hybrid system delivers water throughout 30-plus miles of distribution channels.

This system was designed to accommodate the large starting surge generated from the 25 HP pumps. After initial start-up, the energy generated from the solar array will continue to power the pumps prompting the generators to transition to standby mode.

This custom system included:

  • Modules: 264- LG255 Watt solar modules.  67.32 kW (DC)
  • Mounting System: Schletter FS style fixed ground mount
  • Grid tied inverters: 2- SMA America Sunny Towers, 36 kW each
  • Generator: 80 kW diesel- user supplied
  • Ameresco Solar Power Enclosure
  • 9-SMA America Sunny Island 6 kW inverters
  • 6000 AH Deka Unigy II sealed battery bank
  • SMA America Multi-cluster control unit, and monitoring


The hybrid system was installed as an alternative to operating an 80 kW diesel generator for an extended period each day.

The batteries, charged by the solar array, operate the pump controls and power other nighttime loads. This hybrid system minimizes the use of the diesel generator and also provides a convenient backup power source.

Ameresco Solar was consulted on the initial design and we made several recommendations to lower costs including the in-house manufacturing of the Power Enclosure in our facility. This approach allowed us to fully integrate the 9 SMA Americas Sunny Island inverters, Multi-cluster Control Box and all AC and DC circuits. 

The pre-wired integrated system was tested and housed in a custom built insulated enclosure that was delivered and installed on-site. Minimal electrical connections allowed the end-user to get the system on-line in an expeditious manner.
