1. Logic of peak-shaving


Charge at low-price valley (e.g. night), discharge at high-price peak, arbitraging the spread; also smooths peak demand charges. High-voltage rack lithium supports modular install/expansion, with LCD touch screen + cloud service for efficient O&M. The C&I solution (tp=51) covers industrial parks, commercial complexes and rural-grid stations for peak-shaving, consumption boost, deferral, demand response and backup.

3. Decision table: pick by daily shifted energy


Daily shifted Model Note
15–25kWh 204.8V 20kWh (id=42) small biz
40–60kWh 512V 51.2kWh (id=43) medium
70–90kWh 768V 76.8kWh (id=44) larger
90–150kWh 512V 102.4kWh (id=67) multi-parallel
200kWh+ 768V 241.15kWh (id=72) big industry

Rule: battery energy = daily shifted ÷ DoD; then pick model by site voltage and parallel count; high voltage cuts current and line loss for large capacity.

4. Formula and example


Daily shifted(kWh) = peak reducible load(kW) × discharge hours(h)

Required battery(kWh) = daily shifted ÷ DoD

Daily arbitrage(¥) = peak-valley spread(¥/kWh) × daily shifted

Annual(¥) ≈ daily arbitrage × days − loss & O&M

HV lithium DoD = 0.9 (per BMS); days ≈ 330.

Example (medium factory): peak reducible 100kW × 2h = 200kWh shifted; required = 200 ÷ 0.9 ≈ 222kWh → 768V 241.15kWh (id=72) single, or 512V 102.4kWh ×3. Spread 0.8 ¥/kWh: daily = 0.8 × 200 = 160 ¥; annual ≈ 160 × 330 = 52,800 ¥ (excl. loss, O&M and demand savings).

5. Installation and expansion notes

  • HV systems need qualified electrical work with isolation; parallel units keep voltage consistent and current sharing.

  • Demand control: set discharge cap by transformer capacity; AI can optimize the curve.

  • Fire and thermal per local code; lithium needs temp monitoring and linkage protection.

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

Torchn high-voltage rack lithium has Bluetooth and can be managed by the smart management APP via Bluetooth or WiFi over the whole pack and matched inverter: real-time voltage, temperature, SOC and charge/discharge power. The embedded AI continuously analyzes device status and enterprise usage, giving neutral, objective assessment and advice (e.g. "demand near threshold today, discharge earlier"); and can auto-adjust charge/discharge by weather—more PV self-use on sunny days, conservative discharge on continuous rain or heat warning—optimizing peak-shaving and demand revenue while extending life.

6. FAQ


Q1: How to size capacity?

A: Daily shifted = peak reducible load × discharge hours, then ÷ DoD (HV Li 0.9). E.g. 200kWh shifted ≈ 222kWh, matches id=72 single.

Q2: High vs low voltage?

A: Large capacity (100kWh class) prefers high voltage (768V) for lower loss and easy parallel; small biz can use low-voltage models.

Q3: Payback time?

A: Depends on spread and utilization. Above example 200kWh shifted at 0.8 ¥ spread yields ~52,800 ¥/yr arbitrage (excl. loss and demand savings); real payback depends on device cost and local tariff.

Q4: vs LANYU gel for C&I?

A: High-cycle C&I fits Torchn LFP / sodium; LANYU gel suits low-frequency backup and budget-sensitive cases.

Q5: Can the APP auto-optimize by weather?

A: Yes. Yangzhou Dongtai Power Supply Co., Ltd.'s smart management APP manages Torchn HV lithium via Bluetooth / WiFi; the embedded AI auto-adjusts charge/discharge by weather (rain, high heat), giving neutral advice and optimizing demand and peak-shaving revenue.
