3. Integrated BMS: The battery features an Integrated Battery Management System (BMS) known as BlueNova's proprietary BMMC electronic management system. This BMS is responsible for monitoring and managing various aspects of the battery's operation, such as temperature, voltage, and current, to ensure safe and efficient performance.
4. User-Friendly Interface: The battery comes with a simplified user interface that enables users to perform various activities, including basic onboard monitoring of battery status, advanced diagnostics, firmware updates, and even emergency on-site repairs. This ease of use makes it accessible to a wide range of users.
5. Compatibility: The battery supports serial communication, making it compatible with various inverters, chargers, and other peripheral devices from industry-leading manufacturers such as Victron, Studer, Ingeteam, SMA, Goodwe, and Sunsynk. This compatibility ensures that the battery can seamlessly integrate into existing solar or energy storage systems.
6. Long Warranty: BlueNova offers a generous 10-year product warranty for this battery, providing customers with peace of mind and confidence in its performance and longevity.

Overall, the BN26V-280-7.3K HC appears to be a high-quality and efficient lithium iron phosphate battery with a focus on performance, ease of use, and compatibility with various systems and devices in the renewable energy industry.

The BlueNova® HC batteries offer various methods for integration and connection, including serial communication and parallel connection. Here's some information about these two integration methods:

1. Serial Communication:
   • BlueNova® HC batteries feature serial communication functionality using the CAN (Controller Area Network) protocol.
   • When you connect a BlueNova® HC battery to a compatible inverter, charger, or third-party hardware device, it eliminates the need for manual voltage-based installation procedures.
   • The specific installation procedure for serial integration can vary and is determined by the serial-compatible peripheral hardware you are integrating with.
   • Serial communication simplifies the integration process and allows for better compatibility between the battery and other hardware devices.
2. Parallel Connection with MultiCap™ Technology:
   • BlueNova batteries with 123Smart firmware version 5.4 & higher, as well as BMMC firmware version 2.5 & higher, come equipped with MultiCap™ technology.
   • MultiCap™ technology enables you to connect multiple BlueNova batteries in parallel to increase the overall capacity of your energy storage system.
   • You can parallel-connect batteries regardless of their age difference or rated capacity difference under certain conditions: a. All parallel-connected batteries must have the same nominal voltage (e.g., 52V). b. The largest battery's installed capacity at C2 should not exceed 4 times the installed capacity at C2 of the smallest battery in the same configuration. c. Ensure that the correct firmware versions are installed on all batteries in the parallel configuration and are updated as needed. d. Each battery in the parallel configuration should be within its warranty period.
3. Parallel Connection Configuration:
   • When connecting batteries in parallel, it is recommended to connect them to the inverter/charger from both ends of the configuration. This approach ensures balanced and efficient operation.
   • The exact parallel connection setup and wiring will depend on your specific system and the requirements of the inverter/charger you are using.

By following these guidelines, you can effectively integrate BlueNova® HC batteries into your energy storage system, either through serial communication or parallel connection, depending on your system's needs and compatibility.
