Range-extended energy storage systems are available in product series that offer different power ratings, energy capacities, and generator sizes within a standardised platform. A product series allows for simplified selection, predictable performance, and consistent interface design across multiple project sizes. For INJET HanCang, the series approach reduces engineering customisation for each order while still providing options that match site requirements.
This article describes the structure of a range-extended system series, the performance tiers typically offered, and the criteria for selecting a particular model within the series.
A range-extended system series is built around a common architecture that includes the same control system, communication interfaces, and protection scheme across all models. The differences between models are primarily in the inverter power rating, battery capacity, and generator set size.
INJET HanCang’s series uses a common enclosure design with modular battery bays, allowing the battery capacity to be increased by adding battery modules within the same frame. The inverter is offered in multiple power ratings that share the same control software and physical connections, simplifying installation and training.
The series models are typically identified by the inverter power rating and the battery energy capacity, expressed in kilowatts and kilowatt-hours. For example, a model may be designated by its continuous AC output power, followed by the battery energy at a specified discharge rate.
INJET HanCang’s series includes models covering a power range suitable for commercial buildings, light industrial sites, and small manufacturing facilities. The power ratings are selected to match the peak loads of typical applications, with the generator size matched to the average load expected during extended outages.
For each inverter power rating, the series offers multiple battery capacity options. A smaller battery provides shorter autonomy but reduces capital cost. A larger battery extends the time before the generator must start, which can reduce fuel consumption for short outages.
The choice of battery capacity within a power tier depends on the site’s outage duration statistics and the load profile. INJET HanCang’s series provides capacity options with step increments that allow selection within a range between minimum and maximum values, based on the available space and budget constraints.
The generator size in the series is selected to match the sustained load during range-extended operation. The generator output should be sufficient to supply the average load while recharging the battery at a reduced rate.
INJET HanCang offers generator options within each model that are sized to handle the continuous load and provide a defined recharge rate for the battery. The fuel tank capacity is matched to the generator consumption rate, providing an autonomy duration during range-extended mode that extends beyond the battery’s capacity. Fuel tank sizes are selected to allow operation through a typical multi-day outage without refuelling.
The physical footprint of each model is determined by the battery capacity and the generator size. Larger battery capacity requires more cabinet space or additional cabinets, while larger generators require more floor area and ventilation.
INJET HanCang provides dimensional drawings for each model, including clearance requirements for maintenance access and airflow. The installation requirements include floor loading, anchoring, and environmental separation between the battery and generator sections. The series is designed with standardised interface points for AC connection, DC connection, and communication cabling.
All models in the series share the same energy management system software and user interface, allowing operators to interact with different models using the same procedures. The software includes the same control modes, data logging, and alarm handling across the platform.
INJET HanCang’s control features include remote start-stop, scheduled operation, and load management. The user interface is a touch screen display that shows system status, power flows, and historical data. The remote monitoring platform is consistent across the series, supporting fleet management for customers with multiple installations.
Each model in the series has a performance dataset that includes round-trip efficiency at different power levels, standby consumption, and generator fuel consumption at various loads. These data are used for project financial modelling and operational planning.
INJET HanCang provides efficiency maps for each model, showing the system efficiency as a function of load and battery state of charge. The generator efficiency data is supplied by the engine manufacturer and verified during system testing. The performance data also includes noise levels, emissions data, and thermal rejection values for site planning purposes.
The series is designed to allow capacity upgrades by adding battery modules or replacing the inverter with a higher power unit. The control system software is field-upgradable to incorporate new features or revised control logic.
INJET HanCang offers upgrade kits that include additional battery modules and associated hardware for capacity expansion. The upgrade process is documented in the installation manual and can be performed by trained service technicians. The series architecture anticipates future battery chemistry updates and communication protocol revisions, allowing for component replacement without a full system redesign.
A range-extended energy storage system series provides a standardised platform with performance tiers that simplify system selection and installation. INJET HanCang’s series offers options for power rating, battery capacity, and generator size within a common architecture, supporting a range of commercial and industrial applications with consistent control features and physical interfaces.
