The Deye BOS-A is a professional high-voltage, rack-mounted LiFePO₄ battery system designed for small C&I and high-power hybrid/PCS applications. With an intelligent BMS, high current capability, and modular scaling, BOS-A is built to deliver reliable peak power, maximize self-consumption (TOU), and support stable backup / microgrid operation when paired with compatible Deye inverters.

Two selectable “All-in Rack” configurations (as offered in this listing)

✅ Option 1 — Rack 10+ (All-in)

A complete rack solution with 10× BOS-A battery modules, including PDU + full cabling set for a clean, professional HV installation.

• Nominal energy: 10 × 7.68 kWh = 76.8 kWh

• Usable energy (typ. @ 90% DoD): ≈ 69.1 kWh

✅ Option 2 — Rack 13+1 (All-in)

A higher-capacity rack solution with 13× BOS-A battery modules, including PDU + full cabling set for a turnkey build.

• Nominal energy: 13 × 7.68 kWh = 99.84 kWh

• Usable energy (typ. @ 90% DoD): ≈ 89.9 kWh

Both selections are intended as complete rack packages (“all-in”) so installers can deploy faster with fewer missing parts and a consistent wiring layout.

Why installers choose Deye BOS-A

High-voltage performance for serious systems

• LiFePO₄ chemistry for safety, stability, and long service life

• High output capability: up to 160 A system current (model/config dependent)

• 90% recommended DoD and up to 6000 cycles (EOL 70%) under specified conditions

• 10-year warranty (per manufacturer terms)

Smart protection & monitoring

• Full protection suite: over/under-voltage, over-current, temperature protections

• Cell voltage balancing + intelligent charge/discharge management

• Communication via CAN2.0 and system status indicators for quick diagnostics

Rack format, clean installation

• Designed for rack mounting with a compact footprint

• Indoor enclosure rating IP20 (typical plant room / technical room use)

Compatible Deye inverters and system architecture (per Deye solution documentation)

BOS-A is designed to pair with Deye’s high-power three-phase hybrid and PCS platforms, including (depending on project design and region variant):

• Deye SUN-50K-SG01HP3-EU-BM4

• Deye SUN-60K / 70K / 75K / 80K-SG02HP3 (EU variants shown in Deye materials)

• Deye SUN-100K-PCS01HP3 and SUN-125K-PCS01HP3 (PCS applications)

This ecosystem supports advanced energy strategies such as:

• TOU / peak-shaving: configurable multi-period charge/discharge scheduling

• Generator integration: diesel-generator ready (application dependent)

• Hybrid flexibility: BOS-A supports connection to two inverter DC interfaces for flexible design and redundancy options.

Expansion and scalability

One of the biggest advantages of BOS-A is its modular growth path:

• Series expansion: the platform supports 7 to 21 battery modules in series (system voltage scales with module count).

• Energy scaling (system level): roughly 53.76 to 161.28 kWh nominal across the supported series range (usable energy depends on DoD and configuration).

• Project scalability: Deye’s solution materials also reference parallel / multi-unit architectures for larger on-grid and off-grid projects (final limits depend on inverter model and site design).

You can start with Rack 10+ or Rack 13+1, and later expand the site capacity by moving to larger BOS-A series configurations (subject to inverter compatibility, permitted series count, and installation design).

What’s included in this offer (per your selection)

• 1× BOS-A rack system (cabinet/rack format)

• Battery modules (10× or 13×, depending on chosen option)

• PDU (Power Distribution Unit)

• Complete cabling set (power + communication harnesses as supplied with the rack kit)

Notes for correct application

• HV installation: BOS-A is a high-voltage DC system—installation must be performed by qualified professionals following local electrical and safety regulations.

• Indoor use: IP20 enclosure—install in a protected technical space.

• Exact inverter match: always verify the exact inverter model code and firmware/region variant for your project requirements.
