TITAN Solar Array Simulator

Comprehensive Full-Condition I-V Curve Simulation

TITAN Solar Array Simulator features built-in static and dynamic MPPT test curves that comply with Sandia, EN50530, and CGC/GF004 standards for approximating the real-world output characteristics of PV array under complex weather conditions. Various user-defined metrics through HMI interface support the reproduction of I-V curve, including:

• Voc (open-circuit voltage)
• Isc (short-circuit current)
• FF (fill factor)
• Material Characteristics: monocrystalline silicon, polycrystalline silicon, and thin-film cells
• Realistic shading conditions (cloud cover or dirt accumulation)

More advanced features include the  realistic partial shading (cloud cover or dirt accumulation) simulation capabilities, with a single curve boasting an ultra-high resolution of up to 4,096 points. Combined with an ultra-fast 100ms online curve switching capability, TITAN functions against inverters with the most rigorous PV input validation that closely mimics real-world physical environments.

High Dynamic Response & Ultra-Fast Switching

Frequency matters for testing application against sudden and dynamic load variations. TITAN demonstrates excellent dynamic control loop performance that at rated current, both the 10% to 90% rise and fall times are controlled within 2ms, and under extreme load spans from +90% to -90%, the switching time is less than 4ms. The system features a high voltage slew rate of up to 300V/ms and a current slew rate of 500A/ms - which is a sub-millisecond transient response capability that aligns with the rapid change during dynamic MPPT tracking tests.

High-Efficiency Energy Regeneration & Grid-Friendly Interaction

TITAN Solar Array Simulator is not simply a souce of power yet with comes with an advanced energy regeneration function to recover the load energy back to the AC grid with an efficiency exceeding 94% meanwhile maintains an ultra-high power factor of 0.99 under full-load conditions and strictly limits the input-side total harmonic current distortion (THDi) to below 3%. TITAN eliminates expensive cooling and heat dissipation costs, and achieves better utility-interaction between your test bench.

Ultra-Wide Output Range & Fiber-Optic Parallel Reconfiguration

DMPS and fiber-optic technology allows test bench setup with TITAN Solar Array Simulator to scale up to 10 MW from a single unit of maximum voltage 2000 VDC and 1.0 MW power capability. The superior digital parallel current-sharing algorithm based on ActionPower's patented technology achieves the consistent dynamic response and testing accuracy after parallelling remain completely identical to a single unit.

Testing platform reconfiguration is available to split the 10MVA test platform into several sub master-slave systems for multiple output and multiple test station setup. The system is non-bound to your previous testing requirements and can be reconfigured to meet your evolving test applications.

Powerful Universal Programming & Virtual Internal Resistance

Apart from PV emulation capability, TITAN SAS operates with standard operation modes as that of a programmable DC power supply supporting CV/CC/CP/CR setup, combined with advanced sequence execution through complex 1,000-step transient profiles (Step/List/Wave) with a 1ms dwell time resolution. Integrated internal resistance settings (-2Ω to +2Ω, 1mΩ resolution) reproduces ohmic line drops and battery polarization impedances for replicating the physical status of solar panels.
