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 for commercial and utility scale PV applications found on the market today.
Each SPOT has up to four (4) inputs and can accommodate anywhere from 4 to 8 strings. Each input offers its own maximum power point tracker (MPPT) assuring you achieve the highest level of energy production from your PV array for the minimum amount cost.
Each input offers full galvanic isolation between the PV string and the DC bus. The SPOT is compatible with any PV string voltage including 600, 1000 and 1500 volt PV strings.
The SPOT’s unique, patented design allows output voltage to be fully configurable to the needs of your project using our unique “mass customization” manufacturing strategy.
When combined with the Alencon HUB, SPOTs can be used to perform string level monitoring as well as provide string level, remote control over the PV plant allowing for more cost effective operations and maintenance (O&M). SPOTs can also be used in conjunction with the Alencon GARD to isolate and detect ARC and Ground faults at the string level in the PV array.
The SPOT can be installed anywhere in a PV plant, either between the PV strings and the combiner box to offer string level MPPT or after the combiner box in the SPOT BOX.
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
