Special Features
-
Massive 200A BMS: Most batteries only allow 100A; this unit supports a massive 200A discharge, allowing you to run high-surge appliances like pumps and air conditioners simultaneously.
-
Smart App Monitoring: Integrated Bluetooth and Wi-Fi allow you to track state-of-charge (SOC), temperature, and individual cell health directly from your smartphone.
-
Plug-and-Play Parallelism: Expandable up to 16 units in parallel for a total system capacity of over 160kWh.
-
Advanced Safety Suite: The industrial-grade Battery Management System (BMS) provides automatic protection against overcharge, deep discharge, and thermal runaway.
-
Compact “Double-Power” Chassis: Delivers 10kWh of power in a single enclosure, reducing the wiring complexity and wall space required for two separate 5kWh units
Installation & Mounting
-
Wall Requirements: Must be mounted on a solid concrete or reinforced brick wall capable of supporting >100kg.
-
Clearance: Maintain at least 20cm of clearance on all sides for ventilation and cable management.
-
Mounting Bracket: Secure the heavy-duty bracket first using the provided M8 expansion bolts before lifting the battery onto the hooks.
Wiring & Port Configuration
-
DC Terminals: Features dual positive (+) and negative (-) ports for easy parallel wiring.
-
Communication Ports: * CAN/RS485: For Inverter communication (Default: Pylontech/SRNE protocol).
-
RS232: For PC software debugging.
-
-
Parallel Setup: Support for up to 16 units. When paralleling, use the ADS (Address) Dip Switches to assign each battery a unique ID (Master = 0000).
System Startup Procedure
-
Connect DC Cables: Ensure correct polarity (+ to +, – to -) between battery and inverter.
-
Connect Comm Cable: Link the battery “CAN” port to the inverter “BMS” port.
-
Power On: Toggle the physical Power Switch on the side to “ON.”
-
Soft Start: Press and hold the “Reset/Wake” button for 3 seconds until the LED indicators light up.
Safety & Maintenance
-
Smart BMS: Automatically protects against over-charge, over-discharge, and short circuits.
-
Temperature: Discharge range is -20°C to +60°C; Charging range is 0°C to +55°C.
-
Storage: If stored for over 6 months, the battery must be recharged to 50% SOC to maintain cell health.
