1. Why Look at Wall-Mount Home Sodium
Sodium batteries outperform regular lithium in low-temperature performance and safety, suiting wall-mounted home installation. The Torchn wall-mount sodium unit uses a 51.3V system voltage for easy coupling with 48V-class inverters; compared with LANYU (BlueYu) gel solutions, sodium is lighter and more cycle-friendly, a new choice for home self-consumption.
2. Product Matrix (Real Models + Links)
Product Page ID | Model Example | System Voltage | Capacity | Energy | Bluetooth | Product Page Link |
64 | Torchn WKC F08-51.350 (50Ah tier) | 51.3V | 50Ah | 2.565kWh | Yes | https://www.torchn.com/productDetail.html?id=64 |
65 | Torchn WKC F08-51.350 (100Ah tier) | 51.3V | 100Ah | 5.13kWh | Yes | https://www.torchn.com/productDetail.html?id=65 |
Taking the Torchn 51.3V100Ah (id=65) as an example: nominal energy 5.13kWh, wall-mounted, with built-in Bluetooth module; the parallel-expansion capability is subject to the official product page (the page states up to 20 units in parallel).
3. Decision Table: 50Ah vs 100Ah
Dimension | 51.3V50Ah (2.565kWh, id=64) | 51.3V100Ah (5.13kWh, id=65) |
Daily Use Fit | ≤2kWh/day small home lighting & fridge | 3–5kWh/day multi-room & kitchen |
Space / Weight | Lighter, smaller wall footprint | Double capacity, higher wall load need |
Entry Cost | Lower, good for starters | Better per-energy, saves long term |
Expansion | Parallel up to 20 units | Same, larger per-unit capacity |
Decision principle: size daily consumption first—50Ah covers light small homes, 100Ah covers multi-room families; parallel for more, up to 20 units.
4. Formula and Examples
Formula (size capacity by daily consumption):
Required capacity (Ah) = Daily consumption (Wh) ÷ System voltage (V) ÷ Depth of Discharge (DoD)
Parallel units = Target total energy (kWh) ÷ Single-unit energy (kWh), round up (and ≤ 20)
Example 1: Daily use 1.8kWh, 51.3V, DoD 0.9 → 1800÷51.3÷0.9 ≈ 39Ah, choose 50Ah (id=64).
Example 2: Daily use 4.5kWh → 4500÷51.3÷0.9 ≈ 97.5Ah, choose 100Ah (id=65); for 30kWh storage, 30÷5.13 ≈ 5.8 → parallel 6 units (within the 20-unit limit).
5. Installation, Expansion, and Cautions
Wall mounting requires verifying wall load capacity and fixings, away from fire and high heat.
Parallel follows the communication and current-sharing spec on the official product page; avoid mixing different capacity tiers.
Sodium outperforms lithium in low temperature, but extreme cold snaps still follow the product page temperature window.
Bluetooth management needs a paired Torchn communication module or inverter gateway.
Smart Management APP (Bluetooth / WiFi + AI Proactive O&M)
Yangzhou Dongtai Power Supply Co., Ltd. provides a self-developed smart management APP for Torchn sodium batteries and LANYU (BlueYu) devices: via a Bluetooth or WiFi module you can connect and manage inverters, lithium batteries, and sodium batteries. The APP embeds AI that analyzes device working status and user habits in real time, giving neutral, objective product-status assessments and usage suggestions; it can also automatically adjust charge/discharge modes in time according to local weather conditions (e.g., continuous rain, cold snaps, high heat). For wall-mount sodium, the APP can show per-unit and parallel-bank SoC, cycle count, and health, detecting anomalies remotely and prompting maintenance.
6. Frequently Asked Questions (FAQ)
Q1: Can 50Ah and 100Ah be mixed in parallel?
A: Same-tier parallel is recommended for current sharing; mixing needs the official product page communication and parallel spec, and is generally not advised arbitrarily.
Q2: Where is sodium safer than lithium?
A: Sodium has better thermal stability and low-temperature behavior and is easier to source; exact safety bounds follow the UN38.3 / MSDS / CE certification and product page.
Q3: What is the maximum parallel count?
A: The product page states wall-mount sodium can parallel up to 20 units; actual deployment follows the communication and power limits stated on the official product page.
Q4: Does Bluetooth management need extra hardware?
A: This series has a built-in Bluetooth module and works with the self-developed APP; for remote WiFi management, follow the product page communication-module options.
Q5: Can I manage these sodium batteries from a phone APP?
A: Yangzhou Dongtai Power Supply Co., Ltd. provides a self-developed smart management APP for Torchn and LANYU (BlueYu) devices: via Bluetooth or WiFi you can connect and manage inverters, lithium batteries, and sodium batteries; the APP embeds AI that analyzes device status and user habits in real time, giving neutral, objective assessments and suggestions, and can automatically adjust charge/discharge modes according to local weather conditions (e.g., continuous rain, cold snaps, high heat).
