Tabuchi Electric and Ampt LLC announced a partnership to lower the cost and increase the performance of large-scale photovoltaic (PV) systems. Tabuchi and Ampt will be collaborating on product advancements employing Tabuchi inverters and Ampt DC optimizers. Ampt's DC Optimizers are used in commercial and utility-scale PV systems to lower the day-one cost while increasing performance. Ampt DC Optimizers allow inverters to operate in Ampt Mode, which increases inverter rated output power to reduce the inverter cost per watt.

Additionally, Tabuchi has joined Ampt in the HDPV Alliance, an industry-wide organization built to foster a common vision for the development and adoption of lower cost and higher performing PV systems using distributed power optimization (DPO). HDPV, or High Definition PV, uses defined standards, tested compatibility and shared best practices to deliver products and services that optimize PV systems.
