Wall-Mounted Lithium Battery Energy Storage System
The TOPTEC DKM Series wall-mounted lithium iron phosphate (LiFePO4) energy storage battery is designed for residential and small commercial/industrial applications. It comes in four mainstream models: DKM24100, DKM4850, DKM48100, and DKM48200. Featuring high-quality prismatic LiFePO4 cells and an intelligent BMS, it offers an extended cycle life and superior safety stability. Its sleek, minimalist design supports easy wall mounting, saving space and simplifying installation. An integrated touch LCD screen provides real-time visibility of key metrics like voltage, capacity, and charge/discharge status. The DKM battery is compatible with most major photovoltaic inverters on the market, enabling seamless communication and integration into distributed PV systems, as well as off-grid and grid-tied home energy storage setups. It delivers clean power to homes, retail stores, small industrial equipment, and agricultural irrigation systems. Multiple units can be paralleled for scalable capacity, flexibly adapting to varying load demands. Standard communication interfaces include RS485, RS232, and CAN, with optional WiFi/4G Bluetooth remote monitoring for anytime, anywhere status tracking.

Core Product Advantages:
Safe and durable battery cells: Lithium iron phosphate (LFP) cells offer superior thermal stability, resisting fire and explosion even at high temperatures. With a cycle life exceeding 6000 cycles under 25°C and 80% DOD conditions, they exhibit minimal degradation over extended use.
Intelligent BMS Comprehensive Protection: Built-in BMS with seven protection functions—undervoltage, overvoltage, overcurrent, overtemperature, balancing, over-discharge, and short-circuit protection. Monitors each cell in real time and actively balances voltage differences to significantly extend battery life.
Wall-mounted installation saves spaceWall-mounted design saves floor space and installs easily on indoor walls. Ideal for home balconies, equipment rooms, and shop walls.
Strong inverter compatibilityIntegrates with major photovoltaic inverters to store solar energy during the day and discharge during peak/valley periods or power outages at night, reducing electricity costs and enhancing energy independence.
Data Visualization + Remote ControlReal-time LCD display of operational parameters. Supports wired and wireless expansion for remote monitoring of SOC, charge/discharge power, and temperature data—simplifying operations.
Flexible scaling designSupports up to 15 units in parallel stacking, flexibly matching capacity needs from small residential energy storage to small commercial and industrial applications.
