1. Product Overview & Key Advantages The ESS 500W / 1004.8Wh Wall-Mounted Energy Storage System is an ultra-compact, all-in-one power solution engineered for residential backup, apartment lighting, desktop workstation power, and light off-grid applications. By packaging a pure sine wave inverter, smart MPPT solar charger, grid charger, and a high-capacity 3.2V 314Ah LiFePO4 battery into a slim wall-mountable chassis, it delivers immediate plug-and-play backup power without complex external wiring.
- Space-Saving Wall-Mount Architecture: Featuring a slim 420 × 290 × 90 mm profile and weighing only 11.0 kg, it mounts securely on indoor walls without occupying valuable living space.
- Reliable Cell Longevity & Safety: Equipped with heavy-duty prismatic LiFePO4 chemistry rated for up to 8,000 cycles, offering comprehensive safeguards against over-charge, over-discharge, low DC voltage, and high thermal loads.
- Low Acoustic Signature: Engineered for home and office environments, maintaining a quiet operating noise level below 40dB.
- Intuitive LED Status Display: Features 4-level SOC battery capacity indicators and a working status indicator on the front panel for instant system monitoring.
