Key Features

• Upgraded V2 16kWh All in One Energy Storage System with A+ LiFePO4 Cells, 6000+ Cycles @80% DOD: Integrated battery and inverter all‑in‑one design, plug‑and‑play for easy installation. Powers household appliances during blackouts, ideal for home solar systems, off‑grid living and unstable‑grid backup scenarios.
• Bluetooth & WIFI Remote Monitoring via Mobile App: This 16kWh All in One ESS enables you to check real‑time SOC, voltage, charging power anywhere, optimize solar self‑consumption.
• 2A Active Equalization BMS System: This V2 16kWh all‑in‑one home energy storage is equipped with advanced BMS featuring 2A active equalization, which improves cell consistency and extends whole‑pack service life.
• Built‑in Aerosol Fire Extinguishing System: 16kWh All in One battery comes with complete over‑charge, over‑discharge, short‑circuit and over‑temperature multi‑layer safety protection, supporting safe indoor operation.
• Expandable Capacity & 3‑Phase Parallel Support: The 16kWh all‑in‑one solar battery allows connecting multiple identical units to expand storage capacity or build a three‑phase power system. We recommend ordering all units at once for optimal matching performance.
• Intelligent Multi‑Source Charging Modes: The 16kWh integrated solar energy storage system supports PV solar charging, mains grid charging, or simultaneous charging from both sources. Auto switch between solar and mains power. It can serve as backup power supply when grid power fails.
• Optional Heating Module: 16kWh All in One Energy Storage System supports optional heating configuration. You may select versions with or without heating to enhance battery performance in low‑temperature environments.

Precautions

•No matter what the charging model is, once the temperature of the cell is above the absolute charging temperature, charging should be stopped.

• Please check the orientation of the positive and negative terminals before packaging.

•Connect the terminal or wire to the battery module, and pay attention to insulation to prevent short circuit.

• When not in use for a long time, the battery should be stored in a cool and dry place (<35°C, 30%~50% SOC, charge and discharge once every 3 months).

• Do not place the battery in direct sunlight or a heat source.

• Do not wear metal jewelry (such as rings, watches, accessories, etc.) when handling the battery unit.

Prohibited matters

Do not charge beyond the maximum charging rate.

Do not disassemble or modify the battery.

Do not throw or hit the battery.

Do not pierce the battery with sharp objects (such as nails, knives, pens, electric drills).

Do not mix with other types of batteries or modular units.

Do not excessively squeeze the battery during use.

Do not place the battery in a high temperature greater than 60°C.

Do not use conductive materials to connect the positive and negative terminals (such as metals, wires).
