Lithium battery module SAJ 5kwh BU2-5.0-HV1 / 5 | Expansion for HS2 series

SAJ BU2-5.0-HV1 / 5: 5 kWh lithium modular storage, high voltage LiFePO4 cells and cable-free quick connection system

Increasing the fee of nocturnal self-consumption and ensuring the electrical supply before commercial network failures requires the integration of high efficiency accumulators that take advantage of each watt generated by the solar boards. The battery module SAJ BU2 HV5 Plus - 5.0 (technical reference Bu2-5.0-hv1 / 5) is presented as the definitive modular component for the series of inverters hS2 single-phase hybrids, providing a predictable, safe and compact energy reserve.

Chemistry LifePO4 without cobalt, scalability in tower and passive thermal management

The storage core of this block uses advanced technology Lithium Ferrophosphate (LifePO4). . By completely dispensing the cobalt in its chemical composition, the equipment drastically elevates its resistance to overheating or internal short circuits, offering a premium residential grade security. . Its structural design is based on stackable modularity : Each block provides a nominal capacity of 5.0 kWh and the system allows connect in series up to 4 battery modules to form a compact tower 20.0 KWh of Total Storage. This flexibilizes the initial investment of the house, allowing us to expand the energy reserve as the needs of the family increase. If you want to optimize daytime uptake to simultaneously supply these accumulators and the consumption of your home, you can review our selected offer of invertersSingle-phase and three-phase.

The delivery and absorption of energy is extremely efficient, processing a maximum current of loading and continuous discharge from 30 a. The energy stored in these chassis directly feeds the house during the night or at moments of light cut through the emergency exit of the tower. To ensure that this block is maintained constantly even in the early hours of the morning, we suggest you verify the photovoltaic power options available in our catalog of lithium batteries and high performance solar modules.

Pre-wired fast connectors, outer IP65 and integrated aesthetics immunity

Constructive engineering of SAJ highlights for its concept Plug-and-play. . The BU2-5.0-HV1 / 5 module incorporates a system of integrated fast connection (Quick Connector) that completely eliminates the use of external power cables or data among the units of the tower. . The blocks are interconnected automatically when physically stacked on top of another, streaming the workmanship time of the installer and achieving an impeccable aesthetic finish free of rough wiring on the wall. . All the chassis is shielded under a sealing certification Ip65, Suitable for outdoor placement exposed to climate change or in residential garages. To ensure a robust and leveling anchor of the entire modular assembly on rugged soil surfaces or walls, it is essential to fix the system with ours structures for and metallic supports of high mechanical strength.

Frequently Asked Questions (FAQ)

1. Can I use this battery module SAJ of 5 kWh with inverters of other brands? No, the module Bu2-5.0-hv1 / 5 it is designed specifically as the official storage block official to integrate within the all-in-one solution of the series SAJ Hs2. Its electronic data interface and its powerful power connections are exclusive of this ecosystem, so it is not compatible with inverters hybrids from other manufacturers.
2. How do the power and data cables connect between the batteries when the tower armed? One of the biggest innovations of the HS2 series is that it does not require any type of exposed wiring between the battery modules. . The blocks have rapid internal connectors (Quick Connectors) Integrated directly in the upper and lower chassis. . When stacking a physically module on another, the DC connections and the BMS communication lines automatically fit cleanly and safely.
3. How many battery modules can I add maximum and what total capacity do I get? The system inverter residential HS2 single-phase allows you to attach a maximum of 4 Battery modules BU2-5.0-HV1 / 5 in a single tower. . By having each block a nominal capacity of 5.0 kWh, you can configure your installation scalable with 1 block (5 kWh), 2 blocks (10 kWh), 3 blocks (15 kWh) or complete the maximum capacity of the system with 4 blocks to reach 20.0 KWh of Total Storage.
4. Is it safe to install this lithium battery bank on an outdoor terrace or garden? Yes, it is completely safe. This module has a hermetic chassis with protection grade classification Ip65, which guarantees a total seal against the penetration of dust and rain from any direction. . In addition, its chemistry of Lithium Cells Ferrophosphate (LIFEPO4) emphasizes internationally by not containing cobalt, offering an outstanding thermal resistance that avoids fire risks to variable climate environments.
