Core Features
Dome-Class Capacity: The Cornerstone of Energy Autonomy

20,480Wh Super-Sized Reserve: Effortlessly handles daily household electricity while supporting multi-day continuous high-intensity usage demands such as whole-house air conditioning, underfloor heating, pool equipment, and electric vehicle charging – eliminating power anxiety entirely.

Intelligent Power Matrix: Driving Every Possibility

Sustained High-Power Output: Supports continuous high-power discharge throughout the day, eliminating concerns about system overload or shutdown when multiple heavy-load devices operate simultaneously.

Seamless Switching Technology: <10ms grid interruption response time delivers more reliable power protection than traditional UPS systems, ensuring critical appliances and office equipment remain operational without interruption.

AI-Powered Energy Brain: Proactive and Efficient Management

Adaptive Learning: The system’s AI deeply learns household consumption patterns, PV generation curves, and local electricity pricing policies, automatically generating and executing optimal charge/discharge strategies to maximise cost savings.

Multi-scenario Modes: Instantly switch between [PV Priority], [Peak-Valley Arbitrage], [Emergency Standby], [Off-Grid Operation] and other modes to flexibly address diverse energy demands.

Ultra-Clear Smart Touchscreen: Revolutionising Interaction

Full-Laminated HD Display: Offers an expansive visual interface, dynamically and intuitively displaying energy flows (from grid, PV, output to loads, battery status).

Comprehensive Control: Users can monitor system status in real-time, customise parameters, receive maintenance alerts, and remotely control via the app – everything at your fingertips.

Fortress-Level Security Design, Foolproof Protection

Military-Grade Lithium Iron Phosphate (LiFePO₄) Cells: Adhering to the highest safety standards, with a cycle life exceeding 6,500 cycles. Capable of lasting over 15 years even with daily charging.

Nine-Layer Intelligent Protection System: Integrates third-generation intelligent BMS (Battery Management System) with AI EMS (Energy Management System), delivering comprehensive hardware-level safeguards including voltage, current, temperature, insulation, and cell balancing.

All-Condition Adaptability: Features an intelligent liquid-cooled thermal management system, ensuring sustained high performance and safety in extreme high/low temperatures while extending system lifespan.

Modular stacking, infinite scalability

Flexible expansion: Supports parallel connection of multiple HS-BG51400 units, effortlessly scaling total capacity to megawatt-hour (MWh) levels to seamlessly accommodate future growth in household energy demands.

Application Scenarios
Luxury residences and off-grid villas: Serves as the core energy infrastructure for entire properties, achieving energy self-sufficiency and creating green, tranquil modern living spaces.

Small Commercial & Community Retail: Provides backup power and daily electricity cost management for supermarkets, restaurants, data centres, significantly reducing operational expenses.

Core of New Energy Ecosystem: Seamlessly integrates with distributed generation systems like solar and wind power to build 100% clean energy microgrids.

Specialised Emergency Power Supply: Delivers exceptionally reliable electricity assurance for disaster command centres, communication base stations, medical clinics, and critical facilities.

Summary
The HS-BG51400 transcends conventional energy storage as a future-oriented ‘Home Smart Grid’. With unparalleled capacity, robust power stability, and highly intelligent AI management, it delivers the ultimate energy solution. Choosing the HS-BG51400 means embracing a more autonomous, economical, and sustainable future lifestyle.

FAQ
1.What is special about lithium batteries?

A: With high energy density, it has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries. Long service life, life span can reach more than 6 years. Light weight, the weight is about 1/5-6 of the lead-acid product under the same volume.

 

2. What is a lithium battery used for?
A: Lithium battery is used for power and energy storage. Like emergency power backup or UPS. Dependable electric and recreationalvehicle power, golf cart, reliable and light-weight marine, solar power storage, solar house, small processing factory, surveillance or alarm systems in remote locations.3.Are your batteries safe?A: Our batteries are safe. All Zwayn batteries use the safest and most stable components, including a LiFePO4 cathode and abuilt-in Battery Management System (BMS). The BMS protects the cells against excessively high or low voltages, high currents,short circuits, and excessive heat or cold. These are the most common causes of battery failures, and we have taken everyprecaution to mitigate these risks in all of our batteries.

4.How do I choose the correct lithium deep cycle battery for my application?
A: In most standard 12, 24, or 48 volt systems, the best choice of lithium battery is LiFePO4 (Lithium Iron Phosphate/
Pouch/Primary battery cell). The voltage of this type of battery is very similar to an AGM and will work great with readily
available system components for your RV, boat, off-grid power system, solar house(TV, refrigerator, washing machine, air
conditioner, water heater, microwave oven, induction cooker, dishwasher, printer, computer),Telecommunication Tower, hybrid &off-grid solar energy system applications.5.Can it be series or parallel for use?A: Yes sir, it can support max. 15 in parallel connection for use, Max 150kwh storage box.

6.Can these battery pack be compatible with my inverter? do you have a company list of the inverter which iscompatible?
A:Yes sir, our battery pack can compatible with most brand of inverter on the market, such as Deye, MUST, SMA, Growatt, Solax,Solis, Sungrow, Sofar, Voltronic, Sorotec, Studer, etc
