Smart Series Stackable Hybrid Energy Storage System
All-in-one 12kW / 16.07kWh–48.21kWh Split-phase
Designed for high-demand residential estates, light commercial facilities, and microgrid applications across North America and global 120/240V split-phase markets. The SUNFiD Smart Series combines a heavy-duty 12kW split-phase hybrid inverter with high-capacity 314Ah LiFePO4 battery modules in a clean, modular stackable tower.
By integrating battery management, power conversion, and rapid grid-to-inverter switching into an all-in-one vertical design, the Smart Series provides whole-home backup, solar self-consumption optimization, and off-grid power autonomy without complex external wiring.
Key Features & Technical Highlights
- Modular Stackable Capacity: Expandable battery storage offering 16.07kWh (1 module), 32.14kWh (2 modules), or 48.21kWh (3 modules) per single tower setup.
- High-Power 12kW Split-Phase Inverter: Delivers 120V/240V split-phase AC output (and up to 18kVA surge capacity) to power high-draw appliances, well pumps, and HVAC units.
- 314Ah High-Density LiFePO4 Cells: Engineered with industrial-grade 314Ah Lithium Iron Phosphate cells, delivering 6,000 deep cycles at 85% Depth of Discharge (DOD) under standard operating conditions.
- Seamless 10ms UPS Transfer: Features a typical 10ms transfer time between bypass and battery/inverter mode, guaranteeing uninterrupted operation for critical electronics and medical equipment during sudden grid outages.
- High-Efficiency Dual MPPT: Equipped with 2 MPPT inputs supporting up to 12kW (6kW + 6kW) PV solar input and a wide MPPT voltage range (90V–450Vdc).
- Multi-Unit Parallel Scaling: Supports parallel operation of up to 6 hybrid inverters for total system expansion in larger residential or commercial setups.
Target Applications
- Luxury Residential & Whole-Home Backup: Supplies continuous 120V/240V split-phase backup power for heavy household loads during grid failures.
- Solar + Storage Self-Consumption: Stores excess daytime solar generation from high-capacity PV arrays for peak evening discharge and time-of-use (TOU) rate arbitrage.
- Off-Grid Microgrids & Remote Infrastructure: Operates reliably in off-grid mode, integrating seamlessly with utility power, solar arrays, or backup diesel generators.
- Light Commercial & Small Business Backup: Protects critical commercial equipment, server racks, and cold storage in small business environments.
