Expandable Solar Battery Storage

The EnergyCell 5 platform allows homeowners and installers to increase battery storage capacity as energy requirements grow. Its modular architecture supports additional battery modules within the manufacturer's approved stack configuration.

Multiple compatible stacks can also be configured into a larger energy storage system, providing flexibility for expanding residential or commercial energy needs.

Intelligent Battery Management and Protection

The included EnergyCell Battery Management System monitors battery voltage, current, and temperature to help maintain reliable operation and protect the connected battery modules.

Automatic stack identification and communication help simplify commissioning, while supported inverter communication allows the battery system to coordinate charging and discharging with compatible energy equipment.

Cold-Weather Performance with Integrated Heating

Each EnergyCell 5 battery module includes integrated heating elements designed to support battery operation in colder climates.

Because lithium batteries have temperature-dependent charging limitations, the heating system helps maintain appropriate battery conditions when ambient temperatures drop. Actual charging availability depends on battery temperature, system configuration, and operating conditions.

LiFePO4 Technology and Integrated Safety Features

The EnergyCell 5 uses lithium iron phosphate battery chemistry, known for its thermal stability and long cycle life in stationary energy storage applications.

In addition to intelligent battery monitoring, the platform incorporates an internal fire-extinguishing module as an added safety feature. These protections work together with the system's electrical controls and approved installation requirements.

Outdoor-Ready Modular Construction

The EnergyCell 5 features an outdoor-rated enclosure designed to resist dust and water exposure. Its floor-mounted, stackable configuration allows the battery system to be assembled without requiring separate wall-mounted battery modules.

The modular design also simplifies future expansion when additional compatible modules and system components are installed according to OutBack Power requirements.

Solar Self-Consumption and Home Backup

When connected to a compatible hybrid or battery inverter, the EnergyCell 5 can store electricity generated by solar panels for later use.

Stored energy can help reduce reliance on purchased utility electricity, support time-of-use energy management, and supply backup power to selected loads during an outage when paired with a properly configured backup-capable inverter.

Applications

• Whole-home and essential-load battery backup systems.
• Residential solar energy storage installations.
• Off Grid Solar Systems and remote properties.
• Hybrid solar inverter systems.
• Small commercial battery storage applications.
• Solar self-consumption and time-of-use energy management.
• Expandable battery storage for increasing energy demands.
• Indoor and outdoor energy storage installations.

Inverter compatibility, available backup power, and installation requirements depend on the complete system design. Verify inverter support and applicable installation requirements before purchasing.
