The Chroma 61815 regenerative grid simulator—also referred to as Chroma 61815 Grid Simulator, 61815 AC Source, or 61815 15kVA regenerative simulator—is a powerful and flexible AC power testing solution tailored for grid-connected products and energy systems. It delivers 15kVA of output power with bidirectional regenerative functionality, meaning it can both source and sink power, making it highly energy-efficient for long-duration and high-power testing.
Engineered for R&D and production environments, the 61815 supports various voltage configurations including single-phase, split-phase, and three-phase outputs. Its wide voltage and frequency ranges allow precise simulation of international power grid standards and conditions. It is commonly used to test solar inverters, energy storage systems, electric vehicle chargers, uninterruptible power supplies (UPS), and microgrid components.
One of its standout features is its regenerative ability—capable of feeding energy back to the grid—significantly reducing power consumption and heat during extended testing. The system includes programmable waveform synthesis, voltage and frequency transient simulation, and harmonic distortion capabilities to validate grid compliance and fault tolerance.
