All in One wall-mounted energy storage system—integrating both an inverter and a battery—specifically engineered for high-efficiency and stable performance in residential and commercial settings.
✅ Highly Integrated: Featuring a unified design with a built-in 3.5kVA pure sine wave inverter and optional 2.56kWh or 5.12kWh Lithium Iron Phosphate (LiFePO4) batteries; this streamlined unit ensures simple installation and maximizes space savings.
✅ Efficient and Flexible: Boasting a peak efficiency of 94%, the system supports a 4000W PV input and a 100A hybrid charging current (combining PV and AC sources), thereby significantly enhancing energy utilization efficiency.
✅ Safe and Durable: Utilizing Lithium Iron Phosphate cathode materials, the system features a metal enclosure with an IP20 protection rating. It operates across a wide temperature range (Discharge: -20°C to 55°C) and holds UN38.3 and MSDS certifications, guaranteeing safety during both transport and operation.
✅ Intelligent Communication:Supports optional RS485, RS232, or WLAN communication protocols, enabling intelligent monitoring for convenient remote supervision and comprehensive energy management.

Build an LED display outside the product group to visualize the overall data and status of the battery pack. You can also DIY the operation functions of the display according to your needs.
Not only can we know whether the remaining available capacity of the battery can meet our demand for the total temporary power consumption, but also know when each single battery and battery pack needs to be replaced and repaired.
A lithium battery can easily be stored for a year. Make sure you maintain a 50%-80% charge when storing, and by recharging every 3-6 months, you will be able to store for much longer.
Know more about how to store your battery.
Exact pricing will vary based on which battery model you choose and how many of them you need to power your home.
For example, the capacity difference between lifepo4 battery 200ah and lifepo4 battery 100ah is 2 times, but the price difference is usually about 1.8 times.
However, an average sized home battery backup system typically costs between $10,000 and $18,000 to run
