As the global energy landscape accelerates toward cleaner and more sustainable models, PV energy-storage systems have become a cornerstone of renewable-energy utilization. In this fast-evolving field, high-precision, high-efficiency testing and validation tools are indispensable. The ANEVH(F) Series Programmable Bidirectional DC Power Supply—equipped with advanced technical capabilities—is redefining how the PV energy-storage industry evolves and innovates.
1. Testing Challenges in the PV Energy-Storage Sector
PV energy-storage systems integrate PV modules, battery packs, PCS/inverters, and energy-management systems. Each component requires rigorous electrical testing throughout R&D, production, and operation, including:
PV simulation testing: Simulating IV curves under various irradiance and temperature conditions to validate MPPT performance.
Battery testing: Evaluating charge/discharge characteristics, cycle life, efficiency, and safety boundaries.
System-level tests: Assessing overall system stability in scenarios such as grid interaction, islanding, and fault conditions.
Traditional test equipment often lacks both flexibility and breadth of functionality, making it difficult to meet increasingly complex requirements. The ANEVH(F) Series offers a breakthrough solution.
