Alencon’s String Power Optimizers and Transmitters (SPOTs) are the most powerful DC-DC optimizers for utility scale PV applications found on the market today. Alencon’s SPOTs can be used in combination with either Alencon’s central inverters, GrIPs or central inverters built by virtually any other major manufacturer. Alencon’s SPOTs offer a truly “best of both worlds” solution, offering the granularity of string inverters while allowing you to take advantage of the lower cents per watt cost of a central inverter while maintaining fewer connections to the grid.

Alencon’s SPOTs offer the following

Maximum Power Point Tracking (MPPT) on each of 4 strings at once

  • Increased energy yield for the entire system
  • Minimize impacts of uneven soiling, cloud cover and module degradation or sporadic damage
  • More energy produced
  • Single SPOTs offer twice the number of MPPT inputs as the next closest competitor

Change Output Voltage to Meet Your Needs

  • Map virtually any variable PV input voltage to any needed output voltage
  • Ideal for incorporating Storage with Solar on the DC-side of the inverter
  • Facilitate the repowering of a failed, lower voltage inverter in a
  • Easily incorporate solar into a Microgrid
  • Assure optimal use of your inverter
  • Flexibly map voltage output with the SPOT's unique Galvanic Isolation technology
  • Most flexible voltage modification found on the market today

Easy to Install

  • Quickly mount and install in the field
  • Faster deployment means lower labor costs

Galvanic Isolation

  • Easily manipulate output voltage relative to input voltage with configurable, integrated magnetics

  • Eliminate the possibility of reverse bias being injected into the PV array for Solar + Storage applications

  • Unrivaled flexibility and safety

  • Not offered by any other solution on the market

Granular Data Collection and System Monitoring via PV-IoT

  • Intuitive monitoring of the performance of your PV plant

  • Maxiumum control over every string

  • Quickly identify problems before they occur
  • The only system of its kind for utility scale PV systems
