Ampt reaches 5 GWh of DC-coupled energy storage projects
DC optimizer company Ampt has reached the milestone of 5 GWh of DC-coupled energy storage projects.
Ampt String Optimizers are DC / DC converters that reduce costs, increase performance and improve the grid response of DC-coupled energy storage systems. PV power plant developers and owners deploy Ampt products for mission-critical applications, including peak shift and peak plant replacement, renewable energy enhancement, and grid support. Solar + storage projects with Ampt range from 20 to 200 MW of PV solar energy in combination with up to 6 hours of energy storage.
One of Ampt’s key differentiators in PV + storage is its high fixed voltage (HFVB) DC bus, which lowers capex costs through the power density and efficiency of both the PV plant and battery system increase. Ampt’s HFVB also simplifies system operations so that DC-coupled systems can achieve a level of grid responsiveness historically associated with AC-coupled systems that are more expensive and less efficient.
Other benefits of systems with Ampt include string-level maximum power point tracking (MPPT), which increases service life by capturing energy that would otherwise be lost due to electrical imbalance in the system. Ampt also enables higher DC / AC ratios (up to 3: 1), meaning more PV power is deployed on inverters and transformers. This lowers overall equipment costs and extends energy storage time.
“Low cost solar with battery energy storage is a clear path to revolutionizing our grid and saving lives by replacing obsolete fossil fuel infrastructures with shippable clean energy. Ampt is working with leading developers and solution providers to accelerate this transition, ”said Levent Gun, CEO of Ampt. “Ampt is committed to realizing this future through continuous innovation.”
