Volthium 51.2-100-RH-3U-C

Volthium 51.2V 100Ah Rackmount Lithium Battery (Heated)

48V LiFePO4 Solar Battery | 5.12kWh Energy Storage | 19″ Rack Mount

The Volthium 51.2V 100Ah Rackmount Lithium Battery is a professional-grade 48V LiFePO4 battery designed for off-grid solar systems, hybrid inverters, and energy storage installations. Built in Quebec by Volthium, this battery is engineered for modular expansion, long lifespan, and safe operation in harsh climates.

Designed to fit standard 19-inch server racks (3U height), this battery provides 5.12kWh of usable energy storage and can be expanded into large battery banks for cabins, homesteads, and off-grid power systems.

With integrated battery heating, smart BMS protection, and UL-certified safety standards, this is one of the most robust lithium battery solutions available for residential energy systems.

Built for Off-Grid Solar Systems

This 48V rackmount lithium battery is ideal for powering:

• Off-grid cabins

• Homesteads and remote properties

• Solar backup systems

• Hybrid solar installations

• Energy storage for inverters

It is fully compatible with popular inverter brands including:

• Sol-Ark

• Lux Power

• Schneider / Conext

• Victron GX systems

This makes it a perfect energy storage solution for modern 48V solar power systems.

Modular Energy Storage

The Volthium rack battery system is designed for scalable solar energy storage.

Each unit provides:

5.12 kWh of energy storage

Multiple units can be stacked in parallel to increase system capacity.

Up to 32 batteries can be combined, creating a battery bank of:

48V – 3200Ah – nearly 164 kWh of total storage

The integrated BMS automatically synchronizes and balances all connected batteries, allowing the entire system to function as one unified battery bank.

Built-In Cold Climate Heater

This battery is specifically designed for cold climates and northern environments.

The integrated heater allows safe operation in temperatures as low as:

• Charging down to −25°C (-13°F)

• Discharging down to −20°C (-4°F)

When the internal battery temperature drops below −7°C during charging, the heater automatically activates to warm the cells.

No manual configuration is required.

This makes the battery ideal for Canadian winters, off-grid cabins, and remote solar installations.

Advanced Lithium Battery Management System

The battery includes a fully integrated Battery Management System (BMS) that provides:

• Over-charge protection

• Over-discharge protection

• Over-current protection

• Cell balancing

• Temperature protection

• Automatic battery bank communication

The BMS allows the battery to operate safely and efficiently with standard solar charge controllers.

Smart Monitoring & System Integration

The battery includes built-in communication interfaces for advanced system monitoring.

Available connections:

• VE.Can communication

• RS-485 connection

This allows direct integration with Victron GX devices, including:

• Cerbo GX

• Color Control GX

• GX Touch

The battery can communicate system data directly to the inverter and monitoring equipment without requiring an additional battery monitor.

Safe LiFePO4 Battery Chemistry

Volthium batteries use Lithium Iron Phosphate (LiFePO4) prismatic cells, one of the safest lithium battery chemistries available.

Compared to traditional lithium batteries used in electronics, LiFePO4 cells provide:

• Higher thermal stability

• Lower fire risk

• Longer lifespan

• Deeper discharge capability

These batteries can be repeatedly discharged to 100% depth of discharge without damage, making them ideal for solar energy storage systems.

Long Lifespan Energy Storage

Volthium lithium batteries are true deep-cycle solar batteries.

Expected lifespan:

• 3000 cycles at 100% depth of discharge

• 6000+ cycles at 90% depth of discharge

This provides many years of reliable energy storage for residential solar systems.

Certifications & Safety Compliance

The Volthium rackmount battery is certified to major North American safety standards.

Certifications include:

• UL9540

• UL1973

• UL9540A (cells)

• CSA certified

These certifications allow installation in residential and commercial energy storage systems.
