Hubble AM-2 5.5kWh 48V Lithium Battery (116Ah) for Solar and Backup Power

The Hubble AM-2 is a high-performance 48V lithium battery designed for modern solar storage and backup power systems where fast response, strong discharge capability, and clean inverter communication are important. This battery is built to operate as a smart energy storage module, not just a “battery box”, meaning it includes an advanced BMS that monitors and protects the cells while also communicating with compatible inverters via CAN bus. The result is a more stable system that can manage charge and discharge safely during daily cycling, peak load events, and unexpected power outages.

Where the Hubble AM-2 fits in a system

The AM-2 is intended for low-voltage (48V) battery systems used in residential and light commercial installations. It can be used for solar self-consumption (storing excess PV and using it later), or as a backup battery bank that keeps essential loads running when the grid is unavailable. Because it supports parallel expansion with communication, it is also suitable for customers who want to start with a single battery and scale capacity later without redesigning the system.

48V battery system with 1C performance

Unlike slower “low current” storage batteries, the Hubble AM-2 is rated for 1C performance, meaning it is designed to charge and discharge at high continuous current levels relative to its capacity. This is valuable in real-world systems where loads can ramp quickly (kettles, pumps, compressors, workshop equipment, or multiple circuits switching on). A strong continuous current rating helps the battery support these conditions more confidently when paired with a compatible inverter and correctly sized DC cabling and protection.

Advanced BMS protection and current limiting

The AM-2 includes an advanced BMS with current limiting functionality. In practical terms, this means the battery is designed to protect itself and the system against unsafe conditions such as over-charge, over-discharge, and over-temperature. In a solar-and-backup environment, the BMS is the “traffic controller” that helps keep the battery operating within safe electrical and temperature limits during both charging and discharging.

CAN bus integration and parallel scalability

For clean inverter integration, the AM-2 provides CAN bus communication and is designed to integrate with leading inverter brands that support CAN battery protocols. It also supports parallel expansion up to 15 battery packs with full communications, which is important for larger capacity systems because the batteries can coordinate status and operating limits as the bank grows. This makes it easier to scale storage capacity for longer backup duration or higher sustained load support.

Installation flexibility and build quality

The battery is designed for wall mounting or shelf/rack installation, with heavy-duty side handles to assist with handling and mounting. The enclosure is a white bake-lacquer steel case, suited to indoor installation where the battery is protected from harsh weather exposure. This format makes it practical for utility rooms, plant rooms, garages, server rooms, or other protected installation areas where tidy cable routing and safe access are required.

Optional monitoring and system visibility

The AM-2 supports optional remote monitoring via the Hubble Cloudlink. For customers or installers who want additional visibility, remote monitoring can help with checking battery status, basic system performance, and troubleshooting in supported configurations.

Important setup notes for best results

Use correct DC protection, cable sizing, and inverter battery settings as specified by the inverter manufacturer and installer. Where long service life is the priority, follow the recommended charge current guidance and avoid unnecessarily aggressive charge profiles. In systems designed for frequent power outages, ensure the battery bank capacity is correctly matched to the real load demand to prevent repeated deep cycling beyond the intended operating strategy.
