Hubble AM-5 5.12kWh 51.2V LiFePO4 Low Voltage Battery

Overview of the Hubble AM-5 5.12kWh Battery

The Hubble AM-5 5.12kWh battery is a low-voltage lithium iron phosphate (LiFePO4) energy storage module designed for residential and light commercial solar and backup power systems. Operating at a nominal voltage of 51.2V, the Hubble AM-5 battery is engineered for daily cycling, high current performance, and long service life when paired with compatible low-voltage inverters.

What the Hubble AM-5 Battery Is Designed to Do

The Hubble AM-5 5.12kWh low-voltage battery stores DC electrical energy generated from solar panels or the grid and supplies that energy to a compatible inverter when required. It forms the energy storage backbone of hybrid, backup, and off-grid power systems, allowing loads to remain powered during grid outages or periods of low solar production.

What the Hubble AM-5 Battery Is Not

The Hubble AM-5 battery is not an inverter and cannot produce AC power on its own. It does not contain MPPT charge controllers, AC outputs, or grid synchronization hardware. The Hubble AM-5 is a low-voltage battery only and must not be connected to high-voltage battery systems.

System Type and Battery Voltage Class

The Hubble AM-5 5.12kWh battery is designed for 48V-class low-voltage battery systems. With a nominal operating voltage of 51.2V, it is compatible with low-voltage hybrid and off-grid inverters that support lithium batteries via CAN-bus communication. It is not suitable for high-voltage battery inputs or string battery systems.

Battery Chemistry and Internal Construction

The Hubble AM-5 uses lithium iron phosphate (LiFePO4) prismatic cells, selected for their thermal stability, high energy density, and long cycle capability. The battery incorporates an integrated battery management system that provides voltage protection, current limiting, cell balancing, and communication with the inverter for safe and controlled operation.

Charge and Discharge Performance

The Hubble AM-5 battery is rated for 1C operation, allowing it to deliver high continuous charge and discharge currents without compromising stability. This makes the Hubble AM-5 5.12kWh battery well suited to inverter systems that experience high surge loads or sustained power demand.

Scalability and Parallel Expansion

The Hubble AM-5 low-voltage battery supports parallel operation of up to eight battery packs with full communication. Parallel connection increases total energy capacity while maintaining system voltage, making the Hubble AM-5 suitable for scalable residential systems and growing energy demands.

Communication and Monitoring Integration

The Hubble AM-5 battery communicates with compatible inverters using CAN-bus protocols, enabling accurate state-of-charge reporting, controlled charge profiles, and system protection. Optional Hubble Cloudlink integration allows cloud-based monitoring, providing visibility into battery performance and system data.
