Vatrer 48V (51.2V) 100Ah WiFi Heated Server Rack Lithium Solar Battery EU - 2 PACK

Why Reliable Energy Storage Matters for Modern Homes In many homes using solar power or backup energy systems, during the day, solar panels may generate plenty of electricity, but without dependable storage, that energy can't be used when families actually need it, at night, during storms, or when the grid fails. Traditional batteries lose efficiency quickly or struggle in cold conditions. The Vatrer 48V 100Ah heated server rack battery is designed to address these real-world challenges. It helps ensure that stored solar energy remains available whenever electricity is needed most. High-Capacity 5.12kWh LiFePO4 Battery with 5000+ Cycle Life For solar energy systems, the Vatrer 48V 100Ah heated battery provides 5120Wh of energy storage, enough to support essential household loads such as refrigerators, lighting, internet routers, and home electronics overnight. Inside the battery are EV-grade LiFePO4 cells, designed for stable performance and long service life, supporting over 5000 charge cycles at 100% depth of discharge. Compared with traditional lead-acid batteries that often degrade within a few hundred cycles, this 48V 100Ah lithium battery maintains consistent voltage output and significantly longer operational lifespan. Built-in 100A Smart BMS Protects the Battery System For energy storage systems that operate continuously, this Vatrer 48V server rack lithium battery includes a built-in 100A Battery Management System (BMS) that monitors voltage, current, and temperature in real time. The system automatically protects the battery from overcharge, overdischarge, overcurrent, short circuit, and extreme temperature conditions. By balancing individual cells and regulating charging behavior, the BMS helps maintain stable performance and prevents conditions that could shorten battery life. This integrated protection simplifies system operation while improving long-term reliability. Self-Heating Supports Charging in Cold Weather Cold temperatures often prevent lithium batteries from charging safely. To address this issue, the Vatrer 48V heated lithium battery includes a heated function designed for low-temp environments. When the battery temperature drops to 32°F, the internal heating system activates during charging, gradually warming the battery. Once the temperature reaches 41°F, the heating stops and normal charging continues. This feature allows the battery to charge safely in winter conditions, making it suitable for solar systems installed in garages, cabins, outdoor energy cabinets, or other colder environments. Smart Touch Screen with WiFi and Bluetooth Monitoring Energy storage systems are easier to manage when system data is visible and accessible. This Vatrer WiFi server rack lithium battery integrates a WiFi intelligent communication module and Bluetooth monitoring system, allowing users to track battery performance locally or remotely. Through the touchscreen display or Vatrer app, you can view state of charge, voltage, current, temperature, and battery status in real time. The WiFi communication module also enables remote monitoring, system configuration adjustments, OTA firmware upgrades, and multi-battery management. Rack-Mount Design Allows Flexible Installation The Vatrer rack-mount lithium battery uses a server rack design that allows it to integrate easily into energy storage cabinets or battery racks. Its internal structure is reinforced so the battery can be installed horizontally or vertically, depending on available space and system layout. This flexible installation design simplifies system setup and makes maintenance easier for homeowners and installers building modular solar storage systems. Expandable Energy Storage up to 51.2kWh As household energy demand increases, this Vatrer 48V 100Ah heated LiFePO4 battery supports parallel connections of up to 10 units, allowing total energy storage capacity to scale up to 51.2kWh. This modular expansion makes it possible to start with a single 48V lithium solar battery and gradually increase storage as solar production or household electricity usage grows. Multiple Charging Options for Different Power Systems Energy systems rarely rely on a single power source. This Vatrer 48V lithium battery supports several charging methods commonly used in solar and mobile energy systems. Using a 58.4V 20A LiFePO4 charger, the battery can reach a full charge in approximately 5 hours. For renewable energy setups, it can be charged through solar panels connected to a 48V MPPT charge controller, typically requiring about 1500W of solar input on a sunny day. In backup scenarios, the battery can also be charged through a 30A DC-DC charger connected to a generator or vehicle system, ensuring power availability even when solar energy is limited. Why Choose Vatrer 48V 100Ah Heated Lithium Batteries With WiFi Reliable energy storage is not only about capacity, it also depends on safety, durability, and how well the system adapts to real-world energy needs.
