5.12kWh for Solar and Backup Power The Vatrer 48V 100Ah server rack battery stores 5.12kWh in one LiFePO4 battery, so you can build a 48V solar or backup system without connecting several smaller batteries in series. You get one battery for nighttime solar use, essential household loads during an outage, or regular off-grid cycling while keeping the battery system simple. Built-In Protection for Everyday Energy Storage A built-in 100A BMS manages charging and discharging while protecting the battery against overcharge, over-discharge, overcurrent, short circuits, and abnormal temperatures. These protections work automatically during normal operation to help keep your solar or backup power system running safely and reliably. Grade A Cells for Long-Term Cycling Grade A LiFePO4 cells support the repeated charge and discharge cycles that come with daily solar storage. With a cycle life of 5,000+ cycles, this Vatrer 48V 100Ah LiFePO4 battery is built for regular use rather than occasional backup duty alone. That matters when your battery charges from solar during the day and supplies stored energy again after sunset. Storage That Scales with Your Energy Use You can start with one 5.12kWh battery instead of installing your final storage capacity all at once. Parallel expansion allows the system to grow to as much as 51.2kWh as your backup loads, solar production, or daily energy use increase. The same rack-based format stays in place as additional batteries are added. Battery Status at the Rack or on Your Phone The built-in touchscreen lets you check SOC, voltage, current, temperature, BMS status, and individual cell information directly at the battery. Bluetooth monitoring brings the same day-to-day visibility to the Vatrer app when you are nearby. For batteries installed in an accessible utility room, equipment room, or indoor rack, you can check operating status without opening the system or relying only on basic indicator lights. Low-Temperature Protection for Cold Conditions The built-in BMS continuously monitors battery temperature and responds automatically when conditions become too cold. Charging stops below 32°F to protect the cells from low-temperature charging, while discharge stops below -4°F to reduce stress on the battery in extreme cold. This protection helps the battery operate more safely through winter temperature changes. A Rack-Ready Layout That Stays Organized The SPCC steel enclosure protects the battery components inside a rack-based installation. The battery can be installed horizontally or vertically, giving you more flexibility when arranging an equipment rack or dedicated storage area. As the system expands, the consistent server rack form factor keeps multiple batteries easier to arrange and access. Multiple Ways to Recharge This 48V 100Ah LiFePO4 solar battery can be recharged from a dedicated LiFePO4 charger, a solar array, or a generator-based charging system. A 58.4V 20A LiFePO4 charger supports direct charging, while a 48V MPPT controller connects the battery to solar generation. You can rely on solar for day-to-day charging and use a charger or generator-based setup when solar input is limited. Build Your 48V Storage with Vatrer For a 48V solar or backup system built around an accessible rack, this Vatrer battery keeps the setup straightforward and leaves room to expand later. Start with the storage capacity your system needs today and add more when your energy use grows.
