Modern households have never been more dependent on electricity – from daily lighting, kitchen appliances, and office equipment to security systems. A stable and uninterrupted power supply has become the foundation of a quality lifestyle. TCSN Power's all-new Merak SY Series wall-mounted/floor-standing energy storage system is designed around three core principles – flexible expansion, smart management, and long-lasting durability – delivering a one-stop energy storage solution for homes and small to medium-sized businesses.
Three Flexible Capacities, Precisely Matched to Your Needs
The Merak SY Series offers three standard capacities – 5kWh, 10kWh, and 16kWh – corresponding to 51.2V/100Ah, 200Ah, and 314Ah battery packs respectively. Users can easily choose based on daily electricity consumption, solar PV capacity, and desired backup duration. Whether it's basic backup for a small apartment or whole-home energy management for a detached villa, there's a perfect configuration that avoids both waste and shortfall.
Parallel Expansion, Scales with Your Growing Needs
The system supports parallel connection of up to 15 units, expanding total capacity beyond 240kWh – easily accommodating increased household loads, new appliances, or EV charging needs as your family grows. The modular design makes expansion as simple as building blocks, with no need to replace the main unit or rewire – truly delivering "one investment, lifelong benefits."
Ultra-Long Lifespan – A 20-Year Design Life You Can Count On
Built with high-quality prismatic LFP (lithium iron phosphate) cells, the system delivers an impressive 8,000 cycle life at 80% depth of discharge (DOD), with a design life exceeding 20 years. Even with daily charge-discharge cycles, it runs reliably for nearly 22 years – significantly reducing total cost of ownership over its lifetime. One installation, two generations of energy security.
Multi-Layer Safety Protection for Complete Peace of Mind
The Merak SY Series holds multiple international safety certifications, featuring an integrated fire protection module and intelligent BMS (Battery Management System) with comprehensive protection against overcharge, over-discharge, over-temperature, short circuits, and cell balancing. The prismatic LFP cells offer excellent thermal stability – no fire, no explosion – making them safe for indoor installation without any safety concerns.
Smart Interaction, Effortless Energy Management
Equipped with a 4.3-inch HD touchscreen, the system displays real-time status, remaining capacity, and input/output power at a glance. Bluetooth local maintenance and WiFi remote monitoring are also supported, allowing users to check system data, receive fault alerts, and set smart energy strategies like peak shaving and solar priority via a mobile app – making energy management simpler than ever.
Flexible Installation for Diverse Scenarios
Available in both wall-mounted and floor-standing configurations with IP21 protection rating, the system can be installed in garages, balconies, equipment rooms, or outdoor shelters. Compatible with all major hybrid inverters on the market, it offers plug-and-play connectivity with no complex wiring – significantly reducing installation time and labor costs.
