The NBS II PRO 11kW Series is a high-capacity hybrid on-grid and off-grid energy storage inverter designed for robust residential and commercial solar energy systems. Engineered for maximum flexibility and efficiency, it seamlessly manages power from solar panels, the utility grid, and battery storage. A standout feature is its dual MPPT system, allowing for a massive 10kW of solar input across two independent strings. With a powerful 150A charger, compatibility with both lithium and lead-acid batteries, and advanced features like configurable output prioritization and smart load management, this inverter is a future-proof solution for achieving energy independence and optimizing electricity costs.

Key Features & Benefits

1. Hybrid On & Off-Grid Operation:

   • Provides uninterrupted power by intelligently switching between solar, battery, and grid sources. Ideal for both grid-tied savings and backup power during outages.

2. High-Capacity Dual MPPT Solar Charger:

   • Features two independent MPPT trackers with a wide voltage range (60-450VDC), supporting up to 10kW of solar panels. This allows for installation on different roof orientations, maximizing energy harvest.

3. Powerful 150A Charging System:

   • Combines solar and AC charging with a massive 150A current, enabling rapid battery recharge from either source, which is crucial for large battery banks and minimizing grid usage.

4. Advanced Battery Management & Compatibility:

   • Supports both Lithium and Lead-Acid batteries. Includes a battery equalization function for lead-acid and reserved communication ports (RS485/CAN) for advanced Lithium Battery Management Systems (BMS), ensuring optimal battery health and lifespan.

5. Smart Load Management & Configurable Priorities:

   • Allows users to configure AC/PV output usage times and prioritization, enabling intelligent energy allocation (e.g., powering essential loads first) to maximize self-consumption and savings.

6. User-Friendly 5" Touchscreen Interface:

   • A large, colorful LCD with a touch button provides an intuitive interface for real-time monitoring of system status, energy flow, and easy configuration of settings.

7. Robust Protection & Safety Features:

   • Comprehensive protection includes AC overcurrent, AC overvoltage, over-temperature, and overcharge protection, ensuring the safety and longevity of the inverter and connected equipment.

8. Scalable and Communicative:

   • Offers optional parallel function for power expansion and multiple communication options (WiFi, Bluetooth) for remote monitoring and control via smart devices.
