Growatt ARK20.4 High-Voltage Battery System for SPH BH-UP Inverter

This modular and efficient Growatt ARK 20.4 high-voltage battery system is specifically designed to couple with the Growatt SPH BH-UP inverter series, offering a reliable and scalable energy storage solution for residential and commercial solar energy systems.

System Components and Configuration

This complete system has a total usable energy capacity of 20.48 kWh and consists of the following core components:

• 1x Growatt BMS Controller - HVC 60050-C2 (SA00.0001700): The central Battery Management System (BMS) controller for high-voltage setups, essential for safe and optimised operation, monitoring, and communication between the battery modules and the inverter. The connection cables between the BMS and inverter are supplied with the BMS.
• 8x Growatt ARK 2.5H-A2 High-Voltage Battery Module (SD00.0005800): eight stackable battery modules, each providing 2.56 kWh of high-voltage energy storage capacity.
• 2x Growatt ARK 2.5 Battery Base (TV03.0004900): The stable base for vertically stacking and positioning the two battery modules and the BMS controller.
• 1x Growatt ARK 2.5H-A1 Series Cable (GW180.094300) : for connecting the two battery stacks.

Key Advantages

This high-voltage system offers installers and their customers significant operational and logistical advantages:

• Optimal Energy Efficiency: The high-voltage architecture ensures lower current consumption and higher charge and discharge efficiency, resulting in more usable energy.
• Simple Scalability: The modular design allows the capacity to be easily expanded later by adding extra ARK 2.5H-A2 modules (up to a maximum of 25.6 kWh).
• Full Compatibility: Specifically tailored for Growatt SPH BH-UP hybrid inverters, ensuring seamless integration and guaranteed system performance.
• Flexible Installation: The stackable, cable-free module design simplifies installation and reduces the required installation time.
• Long-Term Safety: The BMS controller continuously monitors performance and protects against overcharging, deep discharge, and temperature deviations.
• Longevity and Reliability: Utilisation of cobalt-free LiFePO4 (LFP) chemistry for a long cycle life and enhanced safety.

 Applications

This battery system is the ideal solution for:

• Residential Solar Installations: Perfect for new-build or renovation projects for homes with high self-consumption and a need for emergency power supply (back-up).
• Hybrid Systems: Designed for Growatt SPH BH-UP inverters.

Warranty and Durability

The LFP battery technology used guarantees a robust and safe system.

• Technical Warranty: Growatt offers a standard 10-year warranty on the battery modules.
• Lifespan: The system is designed for a long service life with a high number of charge and discharge cycles.
• IP Rating: The modules have an IP65 rating, offering protection against dust and water jets.
• Operating Temperature: The system is operational within a wide temperature range, allowing for flexibility in placement.
