What is this product?

This is not just a single battery — it is a complete modular scalable energy storage system. Starting with one 48V 100Ah 4.8kWh rack battery, you can add additional identical units in parallel to expand total capacity all the way to 76.8kWh with 16 units connected.

The system uses RS485 and CAN bus communication protocols to allow all batteries to work together as one cohesive bank. A master-slave configuration ensures load balancing, state-of-charge (SOC) synchronization, and coordinated protection via the built-in BMS on each module.

How Does Parallel Connection Work?

Each battery module contains a 100A smart BMS with communication ports. When multiple units are connected in parallel:

• Power cables: Positive terminals connect together; negative terminals connect together (parallel wiring)

• Communication cables: RS485 daisy-chained in series, with one unit designated as Master, others as Slaves

• System integration: All batteries communicate as one virtual battery bank to the inverter via CAN/RS485

Scalability Options:

⚠️ Technical Note: When connecting multiple batteries in parallel, it is critical that all units are identical — same make, model, capacity, age, and BMS generation — to ensure balanced operation. For systems with 3+ units, a busbar system with equal-length cables is recommended.

Parallel Connection Specifications:

Installation Recommendations

By default, standard 1.5m parallel connection cables are included with each battery purchase. The cabinet or rack (not included) must be provided by the customer based on site-specific requirements.

What's Included per Battery Unit:

• 1 × 48V 100Ah Rack Battery Module

• 2 × 1.5m 4AWG power cables (positive & negative)

• 1 × RS485 communication cable (for daisy chain)

• 1 × User manual

Required for Parallel Expansion (Sold Separately or Provided by Customer):

• 19-inch server rack or battery cabinet

• Busbars (recommended for 3+ units)

• Master disconnect breaker (recommended for 8+ units)

Quality & Communication Integration

The battery system supports closed-loop communication with major inverter brands via CAN bus and RS485 protocols. In a closed-loop configuration, the BMS continuously sends real-time parameters — voltage, current, temperature, SOC — to the inverter, allowing the inverter to optimize charge/discharge based on battery status. This ensures:

• Extended battery lifespan through precise charge control

• Automatic current limiting during peak loads

• Fault and alarm reporting to the inverter display

Target customers and scalable applications:
