N8 - Sodium 48V Storage System

Superior Storage — Starting at just 8kWh and scalable all the way up to 64kWh per inverter, the N8 grows with your energy needs. The 8kW inverter runs continuously — up to 16kW peak — and works both off-grid and grid-tied, with two MPPT solar input channels and automatic generator backup built in. It can even replace your existing solar inverter.

Unmatched Safety — The sodium battery chemistry is inherently safe and stable, requiring no active thermal management and no exhaust ventilation. It handles extreme temperatures, survives rigorous safety testing (nail penetration, crush, drop, and more), and retains at least 80% capacity after 3,500 charge cycles.

Climate-Proof Chemistry — With an operational temperature of -40°F to 172°F, sodium-ion technology outperforms lithium in extreme temperatures, making it ideal for year-round outdoor use.

Eco-Friendly — Longer service life means fewer batteries consumed over time and less material waste.

Sustainable Materials — Sodium uses abundant, sustainable materials with a lower environmental footprint than lithium or lead acid.

Inverter Compatibility

Use the included N8 inverter, or connect N8 battery modules to a compatible third-party inverter. The master module communicates over CAN or RS485, and you choose the inverter brand with its DIP switches (see the user guide).

• CAN (recommended) — GoodWe, Pylontech protocol (Deye), Victron, SMA, Sofar, Growatt
• RS485 — SRNE, Growatt
