To address the power tracking accuracy and dynamic response challenges in three-phase PV inverters, this paper proposes a dual-loop control strategy implemented in the dq rotating reference frame, consisting of an outer power loop and an inner current loop.
It supports whole-home or dedicated load backup, integrates with lithium-ion batteries, and delivers up to 11. 4kW of continuous power with split-phase output and rapid switchover for uninterrupted energy supply.
The proposed control strategy is based on the use of a phase locked loop to measure the microgrid frequency at the inverter terminals, and to facilitate regulation of the in-verter phase relative to the microgrid.
Designed for harsh environments and seamless integration, this IP54-rated solution features a 105KW bi-directional PCS, optional air- or liquid-cooled thermal management, and parallel Standardized products, flexible system configuration, free to expand, and can be installed anywhere.
Shipped in a 20ft container, Sunwoda's containerized battery energy storage system (BESS) is an all-in-one energy storage solution for various scenarios.
PowerMagic, with its master-slave architecture design, is compatible with a 320Ah large battery cell design, offering high energy density and a scalable single cabinet capacity of up to 393kWh. This simplifies on-site installation and significantly reduces initial investment costs.
