Growatt WIT 40K-XHU (AF,PID) Battery Inverter

The Growatt WIT 40K-XHU is an advanced hybrid battery inverter, specifically designed for large-scale commercial and industrial applications. This 3-phase system efficiently manages energy flow between solar panels, batteries, and the electricity grid, supporting both on-grid and off-grid functionalities. 'AF' (Active Fan) and 'PID' (Potential Induced Degradation) refer to advanced features that optimise the performance and lifespan of the entire installation.

Compatible Batteries

The Growatt WIT 40K-XHU inverter is compatible with the Growatt AXE HV battery series, such as the AXE 5.0H-E1 EU module in combination with the Growatt AXE 1000100-C1 BMS. These modular battery systems can be configured in various setups to achieve the desired storage capacity, ranging from 30 kWh to 180 kWh.

Key Features

• Multiple MPPT inputs for optimal yield from diverse solar panel configurations.
• Integrated battery input for direct connection to compatible storage systems.
• Supports DC/AC ratios up to 2.0.
• Max. string current up to 32A for compatibility with high-power modules.
• 100% unbalanced output per phase and 150% off-grid overload capacity.
• Intelligent air cooling system with no derating at ambient temperatures up to 50°C.

Main Advantages

• Energy Efficiency: High efficiency of up to 98.2% maximises energy yield from solar installations.
• Scalability: Supports parallel operation in off-grid mode, enabling flexible system expansion.
• Monitoring: Extensive monitoring capabilities via RS485, USB, Wi-Fi, GPRS, RF, and LAN for detailed insights into system performance.
• Grid Stability: Strong grid adaptability, even in weak grid environments (SCR<1.2).
• Ease of Installation: Compact size and relatively lightweight (90 kg) for efficient installation and transport.
• Safety and Durability: Features IP66 protection, Type II SPD on DC and AC sides, and active arc fault circuit interrupter (AFCI).

Applications 

The Growatt WIT 40K-XHU is ideally suited for commercial and industrial projects where energy storage and grid independence are crucial. This includes factories, warehouses, large business complexes, and projects focused on maximising self-consumption, peak shaving, and emergency power supply.

Warranty and Durability

This system is robustly built for long-term, reliable performance. The IP66 rating guarantees protection against dust and powerful water jets. The inverter is designed to function stably within a wide operating temperature range. Warranty terms are available via the official Growatt warranty card and any specific sales contracts.
