AoKu Solution: Modular 16.08kWh battery modules stack from 64.3kWh up to 192.9kWh per rack. Connect up to 8 racks in parallel to easily achieve 1543.2kWh total capacity for pay-as-you-grow scalability.
🛡️ High-Safety Hardware Protection (Breaker & Fuse Isolation)
The Problem: High-voltage DC short circuits pose extreme safety risks to industrial inverter equipment and facility personnel.
AoKu Solution: The ESMU incorporates a 250A DC Circuit Breaker and dual high-rupturing DC fuses, providing instant physical isolation during overcurrent faults to prevent catastrophic electrical damage.
📱 Remote Cloud Diagnostics & Smart APP Monitoring
The Problem: Unmonitored industrial battery banks lead to un-noticed cell faults and costly unscheduled factory downtime.
AoKu Solution: Built-in WiFi telemetry and CAN/RS485 ports transmit real-time voltage, SOC, temperature, and diagnostic logs to the AoKu Cloud app, enabling proactive maintenance before faults occur.
💡 Plug-and-Play Quick Installation & Low Maintenance
The Problem: Complex electrical wiring for high-voltage battery banks increases labor costs and prolongs project commissioning timelines.
AoKu Solution: Pre-engineered modular racks and plug-and-play quick-connect DC terminals streamline onsite cabinet assembly, cutting engineering labor time and maintenance overhead.
