PMA series energy storage converter adopts modular design. It supports power module independent operation and parallel operation. The flexible power conversion system configuration is easy to use, suitable for on-grid small-scale industrial and commercial applications.
【Peak Load Shifting】The leading three-level space vector modulation SVPWM technology of the PCS(power conversion system) enables efficient charging during off-peak hours and discharging during peak hours to minimize energy loss. The on-grid split-phase power control allows it to flexibly adapt to different grid conditions, ensuring the stability and reliability of the peak load shifting process.
【Demand Side Management】 Our modular energy storage system utilizes leading midpoint balance technology and adapts to unbalanced and nonlinear loads, enabling precise power flow control to respond to grid signals and optimize energy usage. The energy storage module system also supports remote upgrades and integrated local fault recorders, facilitating advanced remote management and monitoring for large-scale distributed demand-side management systems.
【Emergency Power Supply】Our energy storage converter uses well-established industrial IGBT power modules and independent air duct fan cooling, ensuring high stability and reliability of the system during emergencies. It supports off-grid operation and can handle unbalanced and half-wave loads, ensuring a stable power supply even when the grid is completely down.
【Dynamic Expansion】The modular power converters utilize standardized power capacity modules and a 19-inch 3U standard size design, which support horizontal or vertical installation, making physical expansion simple. Our modular energy storage products support the parallel operation of multiple machines, allowing modules to be easily added to meet growing power demands and enabling seamless dynamic expansion.
