The NBS II PRO 3.2kW/24V is a compact yet powerful hybrid solar inverter designed for reliable off-grid and optional on-grid power solutions. Building on the series' reputation, it integrates a pure sine wave inverter, a high-capacity MPPT solar charger, and an AC battery charger into a single, efficient unit. Perfect for medium-sized homes, workshops, or backup power systems, it seamlessly manages energy from solar panels, the grid, or a generator, providing stable power with features designed to protect and extend battery life.

Key Features

• Robust Power Output: Delivers a continuous 3.2 kW (3200 VA) of pure sine wave AC power with a high surge capacity of 6.4 kVA, capable of starting and running motor-driven tools, appliances, and other demanding loads.

• High-Efficiency MPPT Charger: The built-in 100A MPPT solar charger can handle up to 3500W of solar panels, maximizing energy harvest from a wide MPPT voltage range (30–450 VDC) for faster battery charging.

• Battery Life Extension: Features battery equalization for lead-acid batteries to balance cell voltages and extend the overall battery lifecycle, ensuring long-term reliability and performance.

• Fast and Adaptive Transfer Switching: Provides a ultra-fast 10ms transfer time for sensitive electronics like computers and a standard 20ms for general appliances, ensuring optimal compatibility and uninterrupted operation.

• Multi-Source Charging Flexibility: Can charge the battery from both solar panels (100A max) and the AC grid/generator (80A max), with an intelligent system that manages the total charge current up to 100A.

• Wide Operating Voltage Range: Accepts a broad AC input range (90–280 VAC), ensuring stable performance even with unstable grid power or generator sources, making it ideal for rural or areas with poor grid quality.

• Lithium Battery Ready: Equipped with communication ports (CAN & RS485) for seamless integration with a Battery Management System (BMS), enabling safe and optimized charging for modern lithium batteries.

• Compact and Durable Design: Maintains a compact form factor and light weight (5.5 kg) while supporting a higher operating temperature range (up to 60°C), suitable for various installation environments.

• Remote Monitoring Capability: Offers standard communication interfaces and optional WiFi/Bluetooth modules, allowing for convenient remote monitoring, control, and system configuration via a smartphone app or computer.

• Optional On-Grid Functionality: Provides the option for on-grid connection, enabling potential energy export (where permitted) and offering flexibility for future system expansion into a grid-tied setup.
