Behind-the-meter (BTM) DC microgrids are gaining attention as a means to improve efficiency, resilience, and renewable integration. By reducing conversion stages, DC architectures simplify the coupling of solar PV, batteries, and power electronics–dominated loads. This is particularly relevant for data centers, where medium-voltage rectifiers and direct DC distribution can streamline the power chain, improve efficiency, and enable seamless integration of on-site resources. While DC microgrids promise benefits in reliability and grid-interactivity, they also raise challenges in protection, grounding, and interoperability with AC systems.
