Next-Gen 15.36kWh Sodium-Ion Battery (with Heater)

15.36 kWh sodium-ion (Na-ion) home energy-storage battery with built-in heater — the W16-5C is a wall-mounted Na-ion battery for residential solar systems, compatible with hybrid grid-tied and off-grid inverters from multiple brands.

Built on 48 V / 320 Ah Na-ion cells (15.36 kWh), with an independently designed BMS, ~99% conversion efficiency and 9,000-cycle life at 80% DoD. Standard 160 A charge/discharge (200 A max). The built-in heater warms the cells for smooth charging below 0 °C, enabling charging -40 to 55 °C and discharging -40 to 60 °C, with RS232 / CAN / RS485 communication.

• Triple BMS cutoff for overcharge, over-discharge and short-circuit, plus 300 °C thermal-runaway and puncture/cut resistance
• Scalable up to 20 units in parallel for 307.2 kWh maximum capacity
• App monitoring with AI life prediction and remote diagnostics
• Extreme -40 to 60 °C operation with IP65 rating and anti-corrosion coating
• Certified to UN38.3, MSDS and Marine Report (per spec sheet)
