BMS management module SAJ High voltage B2-HV BMS | Interconnection Cable Kit

SAJ B2-HV BMS: Central Control Unit for High Voltage Storage Systems, Intelligent Cell Balance and Data Wiring Kit and Power

Ensure maximum durability and total operational safety of a residential lithium storage bank requires an advanced centralized control system. The module SAJ BU2 HV BMS + Kit Cable (technical reference B2-HV BMS) Acts as the Electronic Orchestra Director of the All-In-One System, in charge of thoroughly supervising each voltage, current and temperature parameter to prolong the life of the accumulators.

Multilayer supervision in real time, active balance and high voltage management

The main function of this component is the active protection of the accumulation tower. The BMS constantly evaluates the load state (SOC) and the health status (SOH) of the Ferrophosphate Lithium (LFP) cells, running automatic voltage rolling processes that avoid overloads or deep discharges in Individual blocks. Your power electronics is optimized to manage continuous flows with a maximum loading and unloading of 30 A, Assimating the photovoltaic injection peaks generated during the hours of greater solar radiation. If your single-family project requires a high-performance solar field set with maximum safety over flat or tilted covers to feed this tower, we advise you to examine our catalog of structures for of structural aluminum.

The entire continuous current regulated by this brain control is efficiently channeled towards the domestic investment stages. If you want to optimize the diurnal consumption of your home or evaluate the totalized modular capacity that this system can govern, we invite you to consult the available offer in our specialized menu of batteries high voltage.

Integrated cable kit, IP65 watertight protection and diagnosis in the cloud

This commercial package is supplied next to official Cable Kit, composed of the CC power hoses with isolated quick coupling terminals and the CAN bus communication lines necessary to physically link the upper port of the BMS with the hybrid Inverter. The exterior chassis has a degree of environmental isolation Ip65, certifying a total seal against dust and water projections, which enables its placement both in basements and in the climate-exposed outer facades.

In addition, it benefits from the technology of remote Firmware Update, allowing technical service to optimize remote load algorithms without the need for face-to-face visits. Your thermal dissipation occurs by natural convection passive, maintaining the free environment of mechanical noise (operation less than 35 dBA). If you need to evaluate three-phase conversion equipment or upper power scale for your corporate network, we suggest you review our range of inverters hybrid industry.

Frequently Asked Questions (FAQ)

1. What exact function does the B2-HV BMS module in the battery tower SAJ? The BMS (Battery Management System) It is the brain of control of the entire storage bank. Its main function is individually supervising the voltage, the current and temperature of the lithium cells of the lower BU2 modules. This guarantees that the loading and unloading is carried out fully and safely, protecting the system from possible overheating, short circuits or excessive discharges that may damage the useful life of the equipment.
2. What is the Cable Kit (Cable Kit) that is included with this product? Although the intermediate battery modules are automatically connected to be stated (thanks to their internal rapid connectors), an outer cable set is required to link the end of the storage tower with the hybrid Inverter. This kit includes the high-voltage high voltage current cables properly isolated and data cables for CAN communication, ensuring a clean and safe transmission of energy and sensor readings.
3. How many lithium batteries can a single B2-HV BMS module from SAJ? A single B2-HV BMS control module is optimized to centrally monitor high-voltage flexible modular configurations ranging from a minimum of 1 lithium accumulator block up to a maximum limit of 5 blocks stacked in the same tower, allowing shape managing Secure a storage range that covers from 4.8 kWh to 25.6 kWh according to the series of batteries used.
4. Can the BMS module be installed to the weather exposed to rain? Yes, it is totally suitable for placement on the outside. The chassis of the central control unit has grade environmental protection certification Ip65, which guarantees a hermetic seal against dust and absolute resistance to direct climatic inclemencies such as rain, icy or high environmental humidity.
