SunC SCRA-R-51.2-100(HV) — 20.48–81.92 kWh high-voltage rack battery system

Description

Technical specifications

Capacity in Ah and energy in Wh

20.48–81.92 kWh in the modular SunC SCRA-R-51.2-100(HV) high-voltage system. LiFePO4 modules rated at 51.2 V and 100 Ah form configurations with 4, 8, 16 series-connected modules, with system voltages and energy capacities kept separate in the upper tables. Recommended charge and discharge current is 50 A, with a maximum of 75 A for matching the storage unit to the power equipment. CAN 2.0 and RS485 provide the data interfaces. A rack-mounted IP20 construction, 95% depth of discharge and at least 6000 cycles under the catalogue conditions support regular energy use. Each listed configuration retains its own dimensions and operating voltage, alongside temperature, humidity and altitude data. Original family photographs and a downloadable Markdown reference complete the project information. Nominal voltage, capacity in ampere-hours and energy in watt-hours describe the battery together, with each value serving a different purpose. Voltage identifies the electrical class of the connected circuit, Ah describes capacity at that voltage, and Wh describes the energy reserve. For an initial assessment of operating duration, the wattage of the intended loads can be considered alongside the stored energy. The nominal energy figure characterises the battery itself; the resulting supply duration also depends on the operating pattern and the wider system. The upper tables therefore keep all three quantities separate and link them to the exact model. This supports both an initial size comparison and the detailed preparation of a particular installation.

Temperature ranges for each operating state

The manufacturer data separates charging temperature from discharging temperature. For this family, charging is specified from 0 to 55 °C and discharging from −20 to 55 °C. Keeping the two operating states separate preserves the meaning of their respective values and supports planning for the battery environment. Combined with the electrical specifications, these figures create a coherent technical reference: voltage and current for the connected equipment, capacity and energy for the intended reserve, and temperature for the corresponding operating state. The product Markdown follows the same structure so electrical and environmental values remain linked to the exact version when information is shared.

A complete reference for selection and planning

The product page brings original specifications, actual photographs and application information together. The SunC catalogue is hosted directly on Batterado, and the downloadable product Markdown contains the technical table and description in the selected language. It can be used for comparison, project records or coordination with an installer. System preparation considers the voltage class, required energy reserve, charging values and current capability together with the way the circuit is intended to operate. The exact model identity stays attached to that information from the first selection through a price enquiry and further technical planning. This keeps the chosen configuration easy to communicate within the wider energy project.

Solar energy ready for the evening

SunC HV stores electricity in LiFePO4 cells and provides the battery section of a residential or small commercial energy system. It can take in surplus photovoltaic generation during the day and supply stored energy to a compatible inverter after sunset. The inverter converts the DC energy into AC power for electrical appliances. This links the timing of generation with the way a building is actually used: electricity collected on a sunny afternoon can support evening lighting, cooking equipment or household electronics. The technical tables above give the nominal energy, voltage and current ratings of this exact variant. These values provide the starting point for matching the storage unit to the energy demand, inverter power and intended operating pattern of the installation.

LiFePO4 cells for repeated energy cycles

The SunC HV range uses lithium iron phosphate cells. SunC specifies at least 6000 cycles at 25 + 2 °C, a 0.5 C test rate and an end-of-life criterion of 80% remaining capacity. Keeping those conditions beside the cycle figure makes the specification useful when comparing batteries in the same category. The stated depth of discharge is 95%. The storage unit is designed around a recurring energy cycle in which charging during generation is followed by discharge when electricity is needed. Capacity in ampere-hours and energy in kilowatt-hours describe different aspects of that task. The Ah figure expresses electrical capacity at the stated nominal voltage, while kWh expresses the size of the energy reserve. Both appear together in the model-specific data so the battery can be selected by its actual electrical configuration.

High-voltage storage built from battery modules

The SunC HV rack establishes a system energy reserve by connecting battery modules in series. Each module has a nominal voltage of 51.2 V; the voltage of the complete system follows the selected module quantity. The upper tables therefore distinguish module data from the voltage and energy of the whole installation. Listed configurations are manufacturer variants within one model family and allow the energy size to be selected for the project. A rack arrangement brings the battery units and control section together in an organised assembly. Selection can be based on capacity, system voltage and current capability while retaining the original identity of the module family.

Module and system specifications kept separate

Module voltage, module capacity in Ah, the number of series-connected units and total system energy each have a distinct role in high-voltage battery selection. Each listed configuration therefore retains its own voltage, operating range, energy and dimensions in the specification table. Recommended and maximum current values are given separately. This supports matching the required energy reserve to the battery input of the chosen power equipment. Battery data connections use CAN 2.0 and RS485 interfaces. Communication, system voltage and current class are considered together as properties of the selected assembly during project preparation.

Rack layout, environment and project documents

SunC specifies rack installation, IP20 protection, relative humidity of 5 to 85% and altitude up to 2,000 m. Charging temperature is 0 to 55 °C, discharging −20 to 55 °C and storage −20 to 60 °C. Dimensions retain the manufacturer's two-set designation for the configurations where the catalogue lists it. The original family photograph shows the rack construction, with an additional detail of its upper control section. The catalogue and customer Markdown are hosted directly on Batterado. Module and system specifications remain together in the portable reference for selecting a configuration and preparing the wider energy project.
