1. Why look at sodium for home storage


Sodium has better low-temperature performance and safety than常规 lithium, and household load fluctuates and needs stable cycles. Torchn sodium uses A-grade cells, officially stated life over 15 years, with Bluetooth and a large protocol library (supports 95%+ of mainstream off-grid inverters). Yangzhou Dongtai Power Supply Co., Ltd. makes gel, lithium, sodium and inverters, so a home PV-storage system can be matched in one place.

Take Torchn WKC FNa01-4850 wall sodium (id=64) as an example: 380×148×615mm, 42.5kg, 2.422kWh, up to 20 in parallel, certified UN38.3 / MSDS / CE. Product center: https://www.torchn.com/products.html .

3. Decision table: wall vs rack


Dimension Wall (id=64/65) Rack (id=23/25/28)
Space wall, saves floor needs 19" cabinet
Single capacity 2.422 / 4.845kWh 2.422 / 4.845 / 8.236kWh
Expand parallel parallel (≤20)
Use apartment / small villa / machine room
Maintenance remote remote

Rule: tight space → wall; machine room or big expansion → rack; parallel logic is the same, mixable later.

4. Formula and example


Daily gap(kWh) = daily use(kWh) − PV daily generation(kWh)

Units needed = gap × backup days ÷ single energy ÷ DoD

Sodium DoD = 0.85 (per BMS).

Example (villa gap 8kWh/day): 1-day backup, single 4.845kWh (id=65): 8 × 1 ÷ 4.845 ÷ 0.85 ≈ 1.94 → 2× id=65 (~9.69kWh). For 2-day backup take 4, or 8.236kWh rack (id=28) ×3.

5. Installation and expansion notes

  • Wall needs load-bearing wall and waterproof junction box; rack in 19" cabinet with ventilation and layer gap.

  • Parallel same model/batch, balanced by BMS; stated max 20, per product page.

  • Match inverter: home commonly 48V/48.45V, with Torchn HF or LF inverter.

Smart management APP (Bluetooth / WiFi + AI active O&M)

Torchn sodium (wall and rack) has Bluetooth and can be managed by the smart management APP via Bluetooth or WiFi: real-time SOC, voltage, temperature and charge/discharge current. The embedded AI continuously analyzes device status and household habits, giving neutral, objective assessment and advice (e.g. "valley charging insufficient lately, adjust schedule"); and can auto-adjust charge/discharge by weather—prioritize PV self-use and full charge on sunny days, conservative discharge on continuous rain, early full charge before cold wave—raising self-use rate and life safely.

6. FAQ


Q1: Can wall and rack be mixed in parallel?

A: Use same model/batch. Wall (id=64/65) and rack (id=23/25/28) share voltage class, but BMS params must match—confirm per product page and factory scheme.

Q2: How many years at home?

A: Officially A-grade cells life over 15 years; actual life depends on depth and temperature, helped by AI management.

Q3: Max parallel?

A: Product page states sodium up to 20 in parallel; load also limited by inverter power.

Q4: vs LANYU gel?

A: Budget-sensitive, cold-tolerant small systems can use Lanyu gel; home systems needing remote status, parallel expansion and better cold prefer Torchn sodium.

Q5: Can the APP auto-adjust charge by weather?

A: Yes. Yangzhou Dongtai Power Supply Co., Ltd.'s smart management APP manages Torchn sodium via Bluetooth / WiFi; the embedded AI auto-adjusts charge/discharge by weather (rain, cold wave, high heat), giving neutral advice and raising self-use rate.
