The short version

Key points

  • The Home Stack can be configured with 16kWh, 32kWh or 48kWh of storage, with the largest version remaining under one metre high.
  • The Home Tower combines a 16kWh battery with a separate inverter and can be expanded to as much as 128kWh in a suitable configuration.
  • EnergyLIB says its batteries use LFP cells, have a 10-year warranty and offer more than 8,000 cycles for the Home Stack.
  • The systems include monitoring, fault isolation, heat-spreading barriers and aerosol fire suppression, but correct installation and location remain essential.
  • The slim concept starts at 5.12kWh and is intended for Europe initially, with Australian availability dependent on local approvals and regulations.

Three battery shapes for different homes

EnergyLIB presented three residential battery designs at All-Energy Australia 2026. The Home Stack is a low-profile system, the Home Tower is a narrow upright unit, and the third design is a much slimmer concept intended to suit homes with very limited space.

The Home Stack uses 16kWh battery modules and can be configured for 16kWh, 32kWh or 48kWh of storage. The 32kWh example shown was approximately 75cm high, while the range starts at about 46cm and the largest version remains below one metre. EnergyLIB describes it as one of the shortest batteries in the market.

Home Stack capacity and safety

The Home Stack uses LFP cells and is quoted with a 10-year warranty and more than 8,000 cycles. It has an IP65 enclosure, although the presentation stressed that the installer still needs to select an appropriate location and maintain required clearances.

EnergyLIB says the system monitors individual cells for unusual voltage and temperature behaviour, with faults isolated at the affected pack. The battery also includes barriers intended to limit heat spreading, built-in aerosol suppression and additional short-circuit protection. These are safeguards rather than a guarantee that a fault cannot occur.

The system is paired with six or 10kW single-phase inverters. EnergyLIB says silicon carbide electronics are used to support efficient conversion and quieter operation. Backup capability depends on the inverter, battery, household wiring and any additional equipment required, so buyers need to clarify which appliances will remain powered during an outage.

The upright Home Tower

The Home Tower takes a different approach, placing a 16kWh battery in a single upright, floor-standing unit with a separate EnergyLIB inverter. This format may suit a narrow outdoor or indoor location where a low, wide battery is less practical.

EnergyLIB quotes up to 8kW of battery charging and discharging power. Multiple units can provide up to 128kWh in a suitable configuration, although that is substantially beyond the storage requirement of most homes discussed in the video.

The Home Tower also uses LFP cells, an IP65 enclosure, fault isolation and aerosol suppression. For an outdoor installation, the presentation recommended asking about heat, corrosion exposure and clearance requirements rather than assuming that a compact design will fit every location.

A slim concept for apartments

The third product starts at 5.12kWh and is approximately 18cm deep. It is presented as a potential option for apartments and other homes where depth is more important than maximum storage. The planned European concept is described as expandable from around 5kWh to 20kWh.

The proposed backup output is about 2.4kW, with a claimed changeover time of less than 10 milliseconds. That is aimed at essential equipment rather than running an entire home, and the video notes that the Australian version still needs to be confirmed.

The product is being developed for the European market first. EnergyLIB said it would consider bringing it to Australia once local rules and approvals allow this type of balcony battery. Australian buyers therefore cannot currently treat it as a plug-in option without further information about local compliance.

Questions to ask before buying

The presentation’s main message was to start with the home rather than the largest capacity number. Buyers should examine their electricity use after sunset, how much spare solar is available during the day, available installation space and the amount of backup power required.

EnergyLIB says its energy management system can coordinate charging and discharging with solar generation, household consumption and electricity tariffs. Buyers should also establish who provides support, whether that is the installer, distributor or manufacturer, and who will assist if a component is needed years into the warranty period.

EnergyLIB has an Australian team, stock in New South Wales and a distributor partner, Ultra Batteries Australia, according to the video. Installation must still be completed in a suitable location by a qualified installer.

TechManPat’s conclusion

My takeaway is that the Home Stack, Home Tower and slim concept are aimed at very different homes, so I would choose the available space and actual electricity use before choosing capacity. I would also want clear answers about installation, safety protection, backup loads, Australian approvals and long-term local support before spending my own money.
