The document details the WHES PP-T1, a series of all-in-one, three-phase energy storage systems designed for residential applications. The core value proposition is a fully integrated solution that combines solar energy conversion, battery storage, and intelligent management into a single unit, simplifying the transition to home energy independence.
1. Core Product Offering
The PP-T1 series is not a single product but a range of models offering scalable power and capacity. The system is available in configurations ranging from 5 kW to 13 kW of AC output power and 9.98 kWh to 29.9 kWh of battery energy capacity. This allows homeowners to select a system tailored to their specific energy consumption and solar generation profile. A key feature highlighted is the support for up to 2 times photovoltaic (PV) oversizing, meaning the system can handle a larger solar array than its inverter rating, maximizing solar harvest during sub-optimal conditions.
2. Key Features and Benefits
The document organizes the product's advantages into four distinct categories: Superb, Friendly, Safe, and Smart.
- Superb (Performance):
- High PV Compatibility: Each input string supports a maximum current of 16A or 26A, making it compatible with mainstream 182mm and 210mm high-power PV modules.
- Scalability: Up to 5 units can be connected in parallel, expanding the total system capacity up to a substantial 149.76 kWh for larger homes or higher energy demands.
- Friendly (User Experience & Installation):
- Quick Installation: An integrated plug-in terminal design for connecting battery modules is said to save 75% of installation time compared to manual wiring.
- Versatile Placement: With an IP65 protection rating, the system can be installed either indoors or outdoors.
- Quiet Operation: It operates at less than 25 dB, making it exceptionally quiet and suitable for installation near living spaces without causing noise pollution.
- Safe (Reliability and Protection):
- Comprehensive Safety Design: The system employs a four-layer protection design. Crucially, this includes a built-in aerosol fire suppression system (FSS) as a primary safety measure.
- Certified Safety: It utilizes long-life battery cells and meets stringent international safety standards, explicitly mentioning UL9540A certification for fire safety.
- Smart (Intelligence and Integration):
- Wide Compatibility: The system is designed to be compatible with Virtual Power Plants (VPP), Electric Vehicle (EV) charging, and can work in conjunction with diesel generators for hybrid backup solutions.
- Advanced Management: It supports remote firmware updates and self-diagnosis capabilities, allowing for easy maintenance and feature enhancements over time.
3. Technical Specifications Overview
A detailed specification table covers six models (WH-T1A502 to WH-T1A133). Key technical highlights include:
- Battery: Uses Lithium Iron Phosphate (LFP) battery cells (3.2V/52Ah). The standard battery pack configuration is 1P*30S, with capacities of 4.392 kWh or 4.992 kWh per pack, which are combined to achieve the total system capacity.
- Backup Performance: Features an ultra-fast Emergency Power Supply (EPS) switching time of less than 10 ms, ensuring critical home loads remain powered during a grid outage. The EPS output can handle significant surge loads (1.23x to 2x rated power for 10 seconds) and supports 110% unbalanced output across phases.
- Efficiency: High conversion efficiency is noted, with a maximum PV efficiency of 98.0% and a European weighted efficiency of 97.0%.
- General Data: The system operates in a wide temperature range (from -20°C to +55°C, with an optional heating module for charging at lower temperatures), at altitudes up to 3000m. It uses natural convection for cooling. Communication is enabled via RS485/CAN, and control is available through an LED display or a mobile app. Installation is floor-standing.
- Standards Compliance: The product is designed to comply with a extensive list of international and regional standards, including IEC 62619, IEC 62109, EN 50549, VDE-AR-N 4105, AS/NZS 4777.2, G99, and others, facilitating its deployment in markets like Europe, the UK, and Australia.
Conclusion
The WHES PP-T1 series presents itself as a premium, fully integrated residential three-phase energy storage solution. It emphasizes ease of installation, robust safety with built-in fire suppression, quiet operation, and intelligent features for modern energy management. Its scalability, high PV compatibility, and comprehensive international certifications position it as a versatile candidate for homeowners globally seeking to maximize solar self-consumption, ensure backup power, and participate in advanced energy programs like VPPs.
