48V16S1P 314AH 314AH lifepo4 15kw/h solar energy system Backup Emergency Power Supply

1. System Overview

• 51.2V (16S LiFePO₄): Standard 48V-class battery, high safety and long cycle life

• 314Ah × 51.2V ≈ 16kWh: Large usable energy capacity

• 16S1P: 16 cells in series, stable and commonly used in residential/commercial storage

• Off-Grid: Operates independently without the utility grid

2. Main Application Scenarios

1️⃣ Off-Grid Homes / Farms

Suitable for:

• Rural, mountainous, island, or remote areas without reliable grid power

• Self-built houses, farms, stables, or holiday homes in Europe/Germany

Typical loads supported:

• Lighting, refrigerator, washing machine

• TV, computers, internet equipment

• Water circulation pumps, small electric cookers

???? A 16kWh system usually covers basic household electricity for 1–2 days

2️⃣ Solar Energy Storage (Day Charging, Night Use)

Typical use:

• Daytime: PV panels generate electricity → stored in batteries

• Nighttime / cloudy days: battery supplies power

Benefits:

• Maximize self-consumption of solar energy

• Independence from electricity price fluctuations

• Stable operation in fully off-grid systems

3️⃣ Backup / Emergency Power Supply

Ideal for:

• Areas with frequent power outages

• Users requiring high power reliability

Can support:

• Internet & communication devices

• Refrigeration / freezers

• Security systems

• Small servers or studios

???? Compared with diesel generators: quieter, cleaner, and low maintenance

4️⃣ Commercial, Mobile & Special Uses

Common applications:

• RVs, mobile container systems

• Temporary construction sites

• Outdoor events and exhibitions

• Telecom base stations, surveillance systems

• Small off-grid workshops or factories

3. Load Capacity (Reference)

⚠️ Actual performance depends on:

• Inverter power rating

• Depth of discharge (DoD)

• Simultaneous solar input

4. Recommended System Pairing

• Inverter: 5kW / 8kW / 10kW (48V)

• PV Array: 8–15 kWp (depending on local solar irradiation)

• BMS: ≥200A, with CAN / RS485 communication

• System Types:

  • Pure off-grid

  • Off-grid + diesel generator backup
