JIEYO Stackable Energy Storage Battery — 48 V / 51.2 V LiFePO₄, 5 kWh–25 kWh, CAN/RS485, 6000+ Cycles

について JIEYO スタッキング可能蓄電池 is a modular, high-safety LiFePO₄ storage system engineered for residential and light-commercial solar applications. Each 51.2 V module provides approximately 5.12 kWh of usable energy, and modules stack vertically to scale from 5 kWh up to 25 kWh (and beyond in multi-stack arrays). With LFP chemistry, 6000+ cycle lifeそして 缶/RS485/RS232 communications to mainstream hybrid inverters, it is the practical core of an off-grid, hybrid, or on-grid backup system.

なぜホームストレージにLFPなのか？ NMCや鉛蓄電池に比べ、LFPは以下を提供する。 優れたサイクル寿命, より優れた熱安定性そして flatter voltage curves, which translate into predictable performance and lower lifetime cost per kWh.

True Stackable, Tool-Lite Installation

• Vertical stack design: modules align and lock mechanically; an upper control/BMS pack manages the whole stack.

• Floor-standing or cabinet/rack options: fits utility rooms, garages, equipment closets, or inverter walls.

• Quick electrical interconnects: short, labeled DC busbars/cables minimize wiring time and error.

• Expandable later: start at 5 kWh and expand to 10/15/20/25 kWh as loads grow—no redesign required.

• Clean footprint: narrow depth for tight spaces; front service access simplifies maintenance.

スマートBMS＆システム通信

• パックの監視： real-time voltage, current, temperature, and state-of-charge with cell balancing.

• 保護： over/under-voltage, over-current, short-circuit, over/under-temperature, and charge/discharge cutoff.

• インターフェイス： 缶/RS485/RS232 for closed-loop communication to hybrid inverters and energy gateways.

• Event logging: aids diagnostics and after-sales service; supports firmware updates (where applicable).

• Compatibility: suitable for off-grid, hybrid-grid, and on-grid topologies; inverter brand maps available on request.

グリッド接続モード

• オフグリッド： pair with a compatible hybrid/off-grid inverter for autonomous power where no utility is present.

• ハイブリッド・グリッド： self-consumption, peak-shaving, and time-of-use arbitrage; charge from PV by day, discharge at peak.

• オングリッドバックアップ： maintain essential circuits during outages using an ATS/backup output from the inverter (per local code).

機械・環境工学

• 保護等級 options up to IP54–IP65 (model-dependent), resisting dust and incidental moisture.

• Cooling: 空冷式 thermal path designed for quiet operation and long life.

• Enclosure: steel or alloy shell with powder-coat finish; corner reinforcement for logistics and on-site handling.

• サービス性： modular architecture allows replacement at module level to minimize downtime.

デザインによる安全性

• Cell-level LFP safety with ceramic separators and prismatic/EV-grade cells.

• Pack fusing & contactors with pre-charge circuits to protect busbars and inverter DC link.

• 絶縁と断熱 tested to relevant standards; creep distances respected for high-voltage stacks.

• Compliance documentation: CE / RoHS / MSDS / UN38.3 ロジスティクスと市場参入のために利用できる。

代表的な電気的特性

(*Values vary by configuration; ask for the exact datasheet for your market.)

• Nominal voltage: 51.2 V per module; multi-module stacks managed by BMS.

• Usable energy: ≈ 5.12 kWh per module; 10–25 kWh in 2–5 module stacks.

• Recommended C-rate: 0.5 C continuous; 1 C peak capability depending on inverter and ambient conditions.

• DoD window: 90–100% configurable; standard warranty tied to recommended DoD.

• 往復の効率： > 95% typical with modern hybrids.

• Temperature: charge 0–45 °C, discharge −10–55 °C (typ.); store at 15–30 °C for best life.

• コミュニケーション CAN / RS485 / RS232 with vendor-specific protocols selectable via DIP/firmware.

Use Cases

• Residential PV self-consumption: store daytime solar to cover evening peaks; raise PV utilization.

• Backup power: keep routers, lighting, computers, security systems, fridges and circulation pumps running during outages.

• Peak-shaving & TOU: charge off-peak, discharge on-peak to reduce bills.

• Small C&I micro-grids: stabilize loads in retail, workshops, telecom shelters, and remote cabins.

• RV/Marine cabins & lodges: stationary stacks can support longer stays with quiet, fuel-free energy.

システムサイジングの例（例示）

• 5 kWh (1× module): small apartments, routers/IT + lighting + intermittent appliance backup.

• 10 kWh (2×): typical 3–5 kW hybrid inverter for evening consumption and brief outages.

• 15 kWh (3×): longer autonomy for fridges, work-from-home setups, and pumps.

• 20–25 kWh (4–5×): extended backup for larger homes; pairs well with 8–12 kW PV arrays and 8–10 kW hybrids.

For runtime planning, a quick estimate is:
Runtime (h) ≈ Capacity (Wh) × DoD × system efficiency / average load (W).
At 25 kWh with 90% DoD and 92% system efficiency, you have ≈ 20.7 kWh usable—enough for ~20 hours at 1 kW average.

設置および試運転に関する注意事項

1. Inverter pairing: choose an inverter with a supported CAN/RS485 profile; set battery type to LFP and select the JIEYO (or compatible) profile.

2. DC wiring: observe polarity and torque specs; use appropriately rated DC isolators and fuses per code.

3. 接地： bond enclosure and rack per local electrical code.

4. Ventilation: allow front/side clearance for airflow; avoid sealed cabinets in high-ambient rooms.

5. Firmware & BMS addressing: when stacking, set DIP addresses in ascending order; verify on the inverter screen/app.

6. Commissioning: charge to 100% on first run to sync SOC and perform BMS balancing.

メンテナンスと保管
