PV+storage systems with Ampt generate, capture, and deliver more energy to increase project ROI.
Ampt saves on EBOS, ESS, and inverter costs on day-one to deliver PV+storage systems at the lowest cost per watt.
PV+storage systems with Ampt deliver fast response and simplified connection in both grid-forming and grid-following applications to lower project cost and risk.
Ampt D2B designs are battery-centric. The BESS is deployed and operated like a standalone storage system. Ampt optimizers connect the PV array directly to the DC bus between the battery and inverter. Ampt optimizers automatically follow the battery state-of-charge (SoC) voltage while delivering full available power from PV strings. Optimizer output can be controlled via wireless command.
Ampt D2C designs operate the DC bus at a high, fixed voltage to maximize component cost savings and simplify controls. The inverter, battery converter, and optimizers all operate at a predictable and stable voltage on the DC bus. This avoids the voltage cross-over zones and slow response loops of variable voltage designs.
Ampt optimizers manage the variability of the PV array and automatically match the DC bus voltage while delivering full available power. This enables the use of grid-forming inverters for stronger grids and microgrids.
Systems with Ampt have a battery-supported DC bus, so the inverter responds to grid events from a stable power source to deliver fast grid support.
Ampt systems have fewer grid-facing devices, which reduces modeling complexity and cost while shortening the compliance study process.
