What Are the Specs of Eco-Worthy 48V 100A Server Rack Battery?

The ECO-WORTHY 48V 100Ah Server Rack Battery is a 3U LiFePO4 lithium battery with a 5.12kWh energy capacity, designed for solar storage, off-grid systems, and industrial applications. It features a built-in 100A BMS for safety, Bluetooth monitoring, and supports 6000+ cycles at 80% depth of discharge. Operating within -4°F to 140°F, the rack-mountable unit offers modular scalability and UL1973 certification for commercial use. Pro Tip: Multiple units can be paralleled to achieve up to 30.72kWh capacity in a single cabinet.

What chemistry does the ECO-WORTHY 48V battery use?

This system employs LiFePO4 (lithium iron phosphate) chemistry, known for thermal stability and long cycle life. Its UL1973 certification ensures safety for stationary energy storage applications.

LiFePO4 cells maintain 80% capacity after 6000 cycles at 25°C, outperforming traditional lead-acid batteries by 8-10x. The battery’s thermal runaway threshold exceeds 518°F (270°C), making it suitable for high-temperature environments like solar farms. Pro Tip: Never charge below 32°F (0°C) without low-temp cutoff protection—LiFePO4 can’t absorb charge safely in freezing conditions. For example, a 48V 100Ah unit provides 5.12kWh, enough to power a 1kW HVAC system for 5 hours during outages.

What communication protocols are supported?

The battery integrates Bluetooth monitoring and RS485/CAN bus interfaces for system integration. Users can check SOC, voltage, and temperature via mobile apps.

Bluetooth 5.0 enables real-time monitoring within 33ft (10m), while RS485 supports Modbus RTU for SCADA systems. The CAN bus operates at 250kbps, compatible with major solar inverters like Victron and SMA. Pro Tip: For multi-unit setups, use RJ45 cables to daisy-chain up to 16 batteries without signal degradation. Imagine these communication ports as a bilingual interpreter—they let the battery “speak” both consumer-friendly Bluetooth and industrial CAN bus protocols simultaneously.

How does the BMS enhance safety?

The 100A BMS provides over-voltage, under-voltage, and short-circuit protection with ±1% voltage accuracy across 16 cells.

Balancing current reaches 150mA per cell, reducing voltage deviation to <50mV during charging. The BMS disconnects loads within 15ms of detecting critical faults. Practically speaking, this responsiveness prevents catastrophic failures—similar to how airbags deploy milliseconds before impact. Warning: Avoid sustained discharges above 100A; while the BMS permits 200A pulses (5sec), continuous high-current draws accelerate capacity fade.

What are the physical dimensions?

This 3U battery measures 19″ W x 12.6″ D x 5.1″ H, weighing 110lbs (50kg). The steel enclosure meets IP20 standards for indoor rack installations.

Standard 19-inch rack compatibility allows integration with server cabinets or solar power walls. Unlike traditional lead-acid systems, it requires 67% less floor space per kWh. For example, six units in a 42U rack deliver 30.72kWh—equivalent to 24 lead-acid batteries occupying three racks. Pro Tip: Use vertical mounting brackets when stacking more than three units to prevent chassis warping.

What solar compatibility features exist?

Designed for 48V solar systems, it accepts 58.4V max input voltage through MPPT chargers. Compatibility includes 3000W+ inverters with DC input ranges of 40-60VDC.

The battery’s 100A continuous discharge supports 5kW inverters without voltage sag. With 96% round-trip efficiency, only 4% energy is lost during charge/discharge cycles—compared to 15-20% losses in lead-acid banks. Why does this matter? Over a year, a 10kW solar array paired with this battery would save 800-1000kWh otherwise wasted in conversion losses.
