| Model NO. | LFP All-in-One Energy Storage Battery with Inverter & Controller |
| Energy storage capacity | 14.4kWh |
| Series | Residential energy storage |
Product Overview：
Featuring a 51.2V standard voltage platform, this LFP all-in-one energy storage battery integrates a high-efficiency inverter (conversion efficiency ≥96%) and intelligent controller, directly connecting to 10-20kWp solar systems for real-time solar energy conversion and storage. It supports bidirectional charging/discharging, enabling energy storage during grid off-peak hours to reduce electricity costs while serving as an emergency power source during outages. The integrated design saves 30% installation space, and with an intelligent temperature control system and BMS battery management system, it ensures safe operation in environments from -15°C to +50°C, offering over 3,000 cycles (80% DOD). Ideal for home energy storage, solar self-consumption, peak-valley pricing management, and off-grid backup power, it simplifies energy system configuration while enhancing power reliability.
Key Features:
Integrated photovoltaic inverter, energy storage battery, and energy management system.
Built-in MPPT inverter-controller all-in-one unit with PV interface for direct PV charging.
Equipped with Grade A brand lithium iron phosphate (LFP) cells, ensuring safety, reliability, and long cycle life.
Features dual AC sockets for powering household appliances.
Advanced BMS (Battery Management System) with multiple safety protection functions.

Can it! Basic 20.48kWh, stacked to 30.72kWh like building blocks. A small shop can use 20.48kWh, but if you want a bigger one, you can simply add modules without having to replace the whole machine, saving money and effort.
The battery pack is replaceable! When there is a power outage, replace the battery with a new one and it takes 5 minutes to complete. The cash register and refrigerator keep running. Small convenience stores use this to avoid product damage or data loss, making emergency response extremely efficient.
IP20 can only be placed in a dry room, but it has a wide temperature tolerance of -30 ℃ to 50 ℃. 25kg per module, easy to move, can be used in campsites and construction sites, replacing fuel generators, quiet and environmentally friendly.
