46 S E P T E M B E R / O C TO B E R 2 0 1 7 Alencon Systems LLC will mark the debut of the latest gener- ation of its DC-DC optimizer, the SPOT, at SPI 2017. The SPOT X2 features significantly improved on-board firmware to ensure greater energy yield. Headlining the software improve- ments in the SPOT X2 is an improved maximum power point tracking (MPPT) algorithm that ensures optimal PV power har- vesting under fast changing weather conditions. The SPOT X2 has been recast in a manner to make it easier to install to mini- mize soft costs — such as labor and ancillary installation materi- als — associated with PV retrofits. Minimizing installation costs is key to achieving the highest rate of return on PV retrofits. "With a number of PV assets now changing hands as PV plants get older and PV fleets get consolidated, we are seeing a great deal of interest in retrofitting PV plants to improve energy yield. The SPOT X2 makes performing larger commercial and industrial or utility scale PV retrofits much easier than ever before," explains Alencon Systems President Hanan Fishman. "Retrofitting a PV plant with Alencon's SPOT can significantly increase PV yield by introducing more granular MPPT while at the same time improving safety and decreasing on-going O&M costs." At SPI, Alencon will also be demonstrating the SPOT for its unique application in enabling DC-coupled solar + storage instal- lations. Booth 1115.
