In DC coupled systems, different energy sources like batteries, fuel cells, UltraCaps, photovoltaic panels are connected via a common DC intermediate circuit. Because of the different voltage levels, "DC / DC Buck Boost converters" must actively connect such loads to a constant DC link voltage.
Stercom's String Power Booster SPB_30kW allows simple system configuration and a fast regulation using the bidirectional fast voltage drop mode control. The SPB is available as 30KW / 100A performance class and allows input / output voltages of up to 1000V. The SPB power can be scaled up to approx. 120kW through parallel connection. Since the SPB is preferably used to connect battery and UltraCap strings, we have also integrated two-pole DC isolators, fuses and a string management controller in our SPB_30kW.
The SPB is available as a 19 “module with 4U or as a Mobile Box IP67.
The SPB enables efficient integration of energy storage into DC-coupled industrial systems, reducing grid load through peak shaving. This is particularly valuable for manufacturing plants and infrastructures that require a stable, uninterrupted power supply.
Combines PV systems and UltraCap storage for efficient energy storage and usage. The SPB supports charge regulation and grid stabilization during fluctuating solar yields.
Provides reliable coupling of battery storage and other energy sources. Bidirectional voltage regulation ensures stable power supply for autonomous grids and UPS systems for critical infrastructure.
The SPB can be configured for various energy management tasks, such as load management, emergency power supply (UPS), and grid relief. This makes it an ideal solution for applications requiring flexible DC storage technology.
