SunC SCRA-R-25.6-100S — 2.56 kWh / 25.6 V LiFePO4 battery

Description

Technical specifications

Solar energy ready for the evening

2.56 kWh for self-consumption and evening use of solar energy. SunC SCRA-R-25.6-100S combines 100 Ah at 25.6 V with LiFePO4 chemistry and a manufacturer-developed BMS. The rack enclosure measures 560 × 480 × 225 mm, supporting an organised battery installation for a home or small business. A 95% depth of discharge and at least 6,000 cycles at 25 ± 2 °C, 0.5 C and EOL 80% provide a defined basis for regular charging and discharging. Standard charging at 50 A and maximum charging and discharging at 100 A help match the energy reserve with the power equipment. CAN and RS485 provide the data interfaces. The upper tables contain the electrical and temperature values of this exact version, with a complete Markdown reference available to download. SunC SCRA-R 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 SCRA-R range uses new Grade A lithium iron phosphate cells. SunC specifies at least 6,000 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.

Current ratings and system power

Energy capacity is one part of battery selection; charging and discharging current are equally important for matching the power equipment. The standard charging current describes the regular charging operating point. The maximum charging current defines the upper charging rating, and the maximum discharging current describes the battery's current capability when supplying the connected equipment. Each value has its own row in the technical table. This allows the charger and inverter settings to be coordinated with the selected battery version and intended load. Voltage multiplied by current describes electrical power at a given operating point, whereas energy capacity relates to the available operating duration. Considering both together helps create a balanced system with an appropriate energy reserve and a current rating suited to its intended demand.

Dimensions and operating temperatures

Each capacity version has its own enclosure dimensions, shown beside the electrical specifications in the upper tables. Together, these values support planning for the equipment room and the positioning of associated system components. SunC specifies a charging temperature range of 0 to 50 °C and a discharging range of −20 to 60 °C. The current catalogue supplied by the manufacturer gives a storage range of −20 to 60 °C. Separate rows for charging, discharging and storage preserve the distinction between these operating states and make the data straightforward to use during system planning. Enclosure size supports the physical arrangement, the voltage range supports electrical matching, and the temperature figures describe the environmental conditions for the respective battery mode.

Planning around useful stored energy

A household storage project brings together generation, electricity demand and the way loads are used over the day. The SCRA-R battery contributes a defined energy reserve within that wider system. Its listed voltage range establishes the electrical operating window, while the separate charging and discharging ratings describe how energy moves into and out of the storage unit. Looking at these figures alongside the building's typical evening demand provides a concrete way to choose a capacity. The 95% depth-of-discharge figure and the cycle-life test conditions add further context to that selection. Keeping all of these values in a single model-specific product profile makes it easier to coordinate the battery choice with the rest of the installation and to retain the selected configuration in project documentation.

Rack format for organised energy storage

SunC SCRA-R combines LiFePO4 cells, battery electronics and a rectangular metal enclosure with a front connection area. The rack format helps organise battery equipment within a clearly arranged installation space. The front carries the power connections and controls of the corresponding model, with actual product photographs showing their physical layout. The family offers nominal 25.6 V and 51.2 V versions and several energy capacities, providing a choice for the voltage class of the energy system. Each offer retains its own model identity, capacity and dimensions. System planning can therefore start with a defined enclosure and electrical configuration and coordinate its position with the inverter, charging equipment and electrical connections of the wider installation.

Manufacturer BMS and separate current ratings

SunC specifies its own BMS with multiple battery-management functions for the rack-mounted family. Standard charging is rated at 50 A, with maximum charging and discharging at 100 A. These values have separate rows in the upper tables alongside the operating voltage of the exact model. The 25.6 V batteries have an electrical range of 21.6 to 29.2 V; the 51.2 V versions operate from 43.2 to 58.4 V. This distinction supports matching with energy equipment in the corresponding voltage class. Capacity in Ah and energy in kWh remain separate selection values. A larger energy reserve supports a longer period of using stored electricity, while current ratings describe the transfer of energy into the battery and towards the connected load. Both aspects contribute to a balanced storage-system design.

The exact version and a portable product reference

This model page brings together the technical data of a specific rack battery and original photographs of its construction. Enclosure dimensions are listed separately from the electrical values and remain linked to the corresponding model code. The downloadable Markdown document contains the same identity, tables and application description, making it useful for sharing information between the customer, system designer and installer. The original catalogue is hosted directly on Batterado and also provides a view of the family's other capacity options. Selection can be based on one coherent set of information: the voltage class, required energy capacity, current ratings and physical arrangement. The battery unit remains a clearly described part of the wider energy system and can be retained in the project's technical documentation.
