Products Description
Core Selling Points (Marketing Highlights)
All‑in‑one design – Integrates battery, inverter, and 4G Wi‑Fi router into one compact unit, saving space and reducing external devices.
Dual charging inputs (PV + AC) – Supports both solar panel (with MPPT) and AC mains charging, either simultaneously or with PV priority, offering flexible energy replenishment.
Built‑in 4G Wi‑Fi router – Comes with 4G antenna and Wi‑Fi access point, providing network coverage anywhere, ideal for mobile or remote locations.
Pure sine wave output – Delivers clean power suitable for sensitive electronics, ensuring broad compatibility.
LiFePO₄ battery – Safe, long cycle life, and certified with CE, UN38.3, and MSDS.
Smart wake‑up – Automatically powers on when AC or PV input is connected, eliminating the need for manual start‑up.
Technical Features
| Feature | Description |
|---|---|
| MPPT charging | Efficiency >92%; wide PV voltage ranges (12‑36V for 250W model, 12‑50V for 500W model) maximise solar utilisation. |
| Multiple operating modes | Supports PV‑priority charging (when PV ≥60W), AC bypass, and simultaneous charging/discharging. |
| 4‑stage LED battery indicator | Four green LEDs show SOC from 0‑100%; a separate red LED indicates fault status. |
| Smart charge management | Re‑charging only starts when SOC drops to ≤98% after full charge, avoiding frequent topping‑up; re‑connecting power after an interruption allows immediate re‑charge if SOC <100%. |
| Low‑voltage sleep protection | Automatically shuts down and enters hibernation at SOC = 0% or when a single cell voltage drops below 2.4V, preventing over‑discharge damage. |
| Communication interface | RJ45 port (details not fully specified) for expansion, plus dedicated 4G/Wi‑Fi antenna connectors. |
Product Advantages (vs. Competitors)
Compact and lightweight – Small footprint (215×135×310mm for 250W; 215×205×310mm for 500W), easy to carry or wall‑mount.
Wide operating temperature – Works from ‑25℃ to 55℃ (LiFePO₄: ‑10℃ to 50℃) and humidity 10‑90% (non‑condensing), suitable for diverse environments.
Comprehensive safety protections – Built‑in safeguards against short circuits, reverse polarity, over‑charge, over‑discharge, and mechanical shocks; clear warnings against unauthorised modifications.
Simple operation – Single button control (press 1.5s to power on/off or toggle AC output), user‑friendly interface.
Transparent after‑sales policy – Provides fault self‑check guidance (photo taking, code recording) and clear warranty conditions, reducing user risk.
Accessories and Convenience
Standard package includes: AC charging cable, PV connector (XT60‑F), Wi‑Fi antenna, 4G antenna, and a SIM card slot for 4G connectivity.
Wi‑Fi router configuration: Accessible via web interface at 192.168.8.1 (default SSID:
HAO‑LINK_XXXX, password:123456789); users can customise SSID and password.Antenna placement guidance: 4G antenna requires 360° unobstructed view; Wi‑Fi antenna should be kept away from microwaves, cordless phones, Bluetooth devices, etc., to avoid interference.
Important Reminders (Product Positioning)
Recommended maximum load ≤0.8 kW (though rated power is 250W/500W) – this indicates the product is designed for light‑duty, portable, outdoor, or backup use, not for heavy‑duty appliances.
Prolonged operation at maximum charge/discharge current (>30 consecutive minutes) voids the warranty – emphasises the need to follow standard current ratings to ensure battery longevity.
