Ampt, a DC optimizer firm specializing in large-scale photovoltaic (PV) programs, has launched its i50 String Optimizer – the following technology of its energy administration resolution. The i50 is designed to decrease prices and enhance efficiency of utility-scale PV or PV-plus-storage tasks. The i50 String Optimizer helps solar energy plant builders, homeowners and operators improve clear vitality technology and undertaking ROI whereas enhancing grid resilience and reliability.
The i50 String Optimizer builds on the expertise of Ampt’s i32 String Optimizer to ship larger energy and design flexibility whereas sustaining the extremely accredited i32 capabilities. Notable latest tasks with Ampt optimizers embody a 380 MW PV-plus-storage plant within the California Unbiased System Operator (CAISO) energy grid market, and 390 MW of String Optimizers to Chile’s largest solar-plus-storage plant.
Ampt String Optimizers are DC/DC converters that ship full accessible energy from the PV array at a excessive and glued voltage. The upper voltage permits your entire system to function at a decrease present for a given energy to scale back the fee and amount {of electrical} elements comparable to cables, vitality storage programs, inverters and transformers.
The i50 optimizer gives additional value financial savings by enabling fewer photo voltaic trackers per MW within the system. Ampt’s predictable DC bus voltage additionally simplifies battery and inverter controls to enhance grid responsiveness of the facility plant. As well as, the optimizers carry out most energy level monitoring (MPPT) on every enter to maximise lifetime manufacturing and embody wi-fi monitoring to enhance O&M.
The i50 optimizer achieves substantial energy density with output energy as much as 70 kW, which permits a single optimizer to be deployed on every photo voltaic tracker. By accommodating larger enter currents, paralleled strings of PV modules and versatile string lengths, system designers can maximize the utilization of every photo voltaic tracker with out the everyday string sizing constraints in programs with out Ampt.
Nicely-suited for various purposes, the i50 options enhanced capabilities for utility-scale solar energy crops that use high-power PV modules and photo voltaic trackers and opens new alternatives for system homeowners and builders to decrease the entire value of PV energy crops.
