Titan DC Series

Scalability from hundreds of kW to multi-MW systems: 

The TITAN series covers a power range that extends from component-level validation and string inverters to testing central inverters and large battery stacks. 

It is equipped with modular power blocks from 300 kW to 750 kW and can be connected in parallel to deliver a scalable output power of up to 10 MW.  

Thanks to advanced hardware technologies, communication between the cabinets and dynamic specifications remain unchanged. 

Precision and safety:  

Our products offer high measurement and command update rates of up to 1 kHz. Combined with voltage and current accuracy of ±0.01% F.S., they enable deterministic control and accurate data acquisition for ripple analysis, transient evaluations, and performance benchmarks across all operating points. 

Multi-layered protection mechanisms, including programmable OVP, OCP, OPP, and OTP functions, ensure safe operation of both the simulator and the device under test. Integrated error logging records up to 200 events. Special diagnostic queries support maintenance analysis, system integration, and long-term reliability monitoring.

Efficiency for high-performance and endurance testing:

TITAN is inherently a bidirectional DC power supply. 

Thanks to this feature, bidirectional current flow can be achieved as needed. This enables efficient current draw from the device under test during inverter operation.  

Regenerative operation feeds up to 94% of the absorbed energy back into the grid. This significantly reduces thermal load, energy consumption, and operating costs in PV test environments ranging from several hundred kilowatts to megawatts. 

Solar Array Simulation: 

TITAN is the market-leading solution for high-resolution I-V curve emulation of photovoltaic systems. With up to 4096 discrete points, TITAN offers unmatched resolution and reproduction of the real-world behavior of photovoltaic systems.  

Thanks to extremely short curve update and switching intervals of just 100 ms, we can accurately reproduce rapid irradiance transitions, partial shading events, and temperature-dependent operational shifts. Both standard-compliant and user-defined I-V curves are generated for variant testing. 

Both static I-V curves for evaluating MPPT efficiency in steady-state conditions and dynamic I-V sequences for analyzing transient MPPT tracking are supported. This ensures realistic validation of the inverter control algorithms under practical operating conditions.

The TITAN series sets new standards. It comes standard with PV simulation models that reflect the test methods specified in EN 50530 and Sandia SAS. Users do not need to rely on external modeling tools to generate the legally required test patterns.  

In addition to predefined, standards-based models, user-defined I-V curves can be imported, edited, and sequenced via CSV files or parameterized models. Voc, Isc, fill factor, and temperature coefficients must be taken into account.

Our programmable test recipes enable the execution of complex test scenarios—including sequential fault injection, irradiation ramps, and advanced cycle profiles. Test recipes can include up to 1,000 steps and 10,000 cycles.

Battery simulation:

TITAN features programmable emulation of internal resistance (Rint). This allows the nonlinear and state-dependent behavior of real batteries to be modeled.

The resistance characteristics are clearly defined as a function of SoC and SoH. This enables the simulator to reproduce dynamic voltage drops, current-dependent losses, and efficiency fluctuations as observed in real battery systems. 

This functionality is critical for validating BMS control algorithms, charge termination logic, thermal management strategies, and protection thresholds under dynamic load conditions.  

TITAN chargers and control systems are the future. They implement realistic battery impedance curves, enabling more accurate, repeatable, and risk-free testing than physical batteries. 

TITAN integrates software-defined battery chemistry models that reflect the different electrical characteristics of various battery types. These include LFP, NCM/NCA, LCO, LMO, LTO, NiMH, and lead-acid systems. Each model can be parameterized with cell topology, SoC, temperature, and internal resistance to capture chemistry-specific voltage profiles and dynamic responses.

TITAN supports first, second, and third-order RC equivalent circuit models. This allows TITAN to provide advanced battery behavior customization. In addition, user-defined models can be imported via CSV files. The simulator offers a command update rate of up to 1 kHz. This means fast transient response and closed-loop accuracy. It is therefore ideal for the development and validation of BMS algorithms, converters, and energy storage control systems.
