1. Why outdoor monitoring needs storage backup


Outdoor monitoring points are usually far from the grid and located in forests or river basins, so power continuity decides whether data collection is uninterrupted. Continuous rain, winter low temperatures and thunderstorms all weaken PV input, so local storage is needed as a backup buffer. LANYU gel lead-acid and Torchn sodium batteries can be combined by site load and maintenance conditions, and unified by Torchn off-grid inverters. Yangzhou Dongtai Power Supply Co., Ltd., with over 30 years of battery and inverter manufacturing, can deliver one-stop selection for such "unattended + remote O&M" scenarios.

Take Torchn WKC F08-51.350 rack sodium battery (id=23) as an example: rated 51.3V / 50Ah, 2.565kWh, up to 20 units in parallel, certified UN38.3 / MSDS / CE, with Bluetooth and a large protocol library (officially stated to support 95%+ of mainstream off-grid inverters).

3. Decision table: pick capacity by site load


Dimension Light site Standard site Heavy site
Daily use ≤ 0.3kWh 0.3–1.5kWh 1.5–5kWh
Battery LANYU 12V24Ah gel Torchn 51.3V50Ah Na Torchn 51.3V170Ah Na
Parallel No Optional (≤20) Multi-unit
Inverter 24V low power 24V/48V HF 48V HF
Maintenance Long (gel MF) Remote Remote

Rule: size by "daily use × backup days" with margin; gel suits budget-sensitive, low-temperature small sites, sodium suits standard/heavy sites needing remote status and parallel expansion.

4. Formula and example


Required capacity(Ah) = daily energy(Wh) ÷ system voltage(V) ÷ depth of discharge(DoD)

  • Gel conservative DoD = 0.5; sodium = 0.8–0.9 (per product page / BMS).

  • Backup days N: multiply daily use by N.

Example 1 (forest-fire video): 40W full-day → 960Wh/day, 3-day backup, 12V gel:

960 × 3 ÷ 12 ÷ 0.5 = 480Ah → LANYU 12V250Ah (id=14) or 12V120Ah ×2.

Example 2 (hydrology, 51.3V Na): 80W full-day → 1920Wh/day, 2-day backup:

1920 × 2 ÷ 51.3 ÷ 0.85 ≈ 88Ah → Torchn 51.3V100Ah (id=25).

5. Installation and expansion notes

  • Use IP55+ enclosures outdoor; separate battery and inverter bays for cooling. Sodium works better in cold regions.

  • Parallel same model/batch, balanced by BMS/inverter; max parallel per product page (sodium stated 20).

  • Size PV by "daily use ÷ peak-sun hours"; enlarge backup days in rainy regions.

  • Use 4G / satellite backhaul + local storage to avoid data loss.

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

These outdoor sites are unified by Torchn off-grid inverter + smart management APP: via Bluetooth or WiFi module, the APP connects and manages inverters, lithium and sodium batteries, reading SOC, voltage, temperature and charge/discharge current in real time. The embedded AI continuously analyzes device status and usage habits, giving neutral, objective status assessment and maintenance advice (e.g. "deep discharge lately, re-check load"), and can automatically adjust charge/discharge mode by weather (continuous rain, cold wave, high heat)—conservative discharge on rainy days, full charge on sunny days—reducing on-site maintenance and extending battery life without a visit.

6. FAQ


Q1: Can a forest-fire site with no grid use sodium directly?

A: Yes. Torchn rack sodium (id=23 / id=28) supports parallel expansion with off-grid inverter and PV as an independent backup; size by "daily use × backup days".

Q2: How to choose gel vs sodium?

A: Budget-sensitive, low-power, cold-tolerant light sites can use LANYU gel (id=1); standard/heavy sites needing remote status and parallel expansion prefer sodium. Both are unified by Torchn inverters.

Q3: How many sites can one system cover?

A: Depends on inverter power and battery parallel count. Sodium stated up to 20 in parallel; load limited by inverter rating (e.g. 24V1.5kW / 48V10kW).

Q4: Does low temperature affect backup?

A: Yes, it lowers usable capacity; sodium outperforms gel in cold, so prefer sodium for cold sites and add backup-day margin.

Q5: Can a phone APP manage these remotely?

A: Yes. Yangzhou Dongtai Power Supply Co., Ltd. provides a smart management APP for Torchn and LANYU devices; via Bluetooth or WiFi it manages inverters, lithium and sodium batteries. The embedded AI analyzes status and habits, gives neutral, objective advice, and auto-adjusts charge/discharge by weather, cutting on-site maintenance.
