SPOT: PV String and Array Level
DC-DC Optimizers for
Repowering, Solar + Storage and
Microgrid Applications
Alencon’s String Power Optimizers and Transmitters (SPOTs) are the most powerful DC-DC optimizers available for commercial and utility-scale PV applications today.
Each SPOT features up to four (4) inputs, accommodating between 4 to 8 strings total, with each input equipped with its own maximum power point tracker (MPPT). This ensures optimal energy production from your PV array at minimal cost.
Designed for flexibility, each input offers full galvanic isolation between the PV string and the DC bus. SPOTs are compatible with all standard PV string voltages, including 600V, 1000V, and 1500V strings.
What sets the SPOT apart is its patented design, which allows the output voltage to be fully customizable to suit your project's specific requirements.
When integrated with the Alencon PODD, SPOTs enable string-level monitoring and remote control of PV plants, streamlining operations and maintenance (O&M).
SPOTs offer versatile installation options: they can be placed between PV strings and the combiner box for string-level MPPT or installed post-combiner box within the SPOT BOX, adapting seamlessly to your PV plant’s architecture.
The Alencon SPOT is a cost-effective tool for the following applications:
Alencon’s SPOTs offer the following features, benefits and advantages:
Maximum Power Point Tracking (MPPT) on each of 4 inputs at once
- Increased energy yield for the entire system
- Minimize impacts of string level mismatch including 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
