SolaX Power battery storage systems provide Australian households with efficient solar energy storage, backup power support, and flexible modular expansion. Designed with LiFePO₄ technology, these smart home battery systems help reduce grid reliance and improve long-term energy savings.
The SolaX Power brand is a Chinese company with a global presence that has been operating in the production of inverters and energy storage systems for more than 15 years. The products of this brand are offered with modular design, expandability, and high safety.
These batteries are particularly suitable for households that:
• have predictable nighttime electricity use
• want to reduce reliance on the grid
• intend to expand their energy system in the future
SolaX works with DC Coupled high voltage systems and must be installed with compatible inverters. Installation and commissioning are carried out by the professional Axial team in Melbourne.

SolaX Battery Models Available in Australia
T BAT HS Series (3.6 kWh & 5.1 kWh Modules)
T BAT HS (3.6 kWh modules):
• Expandable capacity: ~7.3 kWh up to ~47.9 kWh
• Output up to ~33.2 kW
• IP65 rating
• Floor or wall mounting
T BAT HS (5.1 kWh modules):
• Nominal capacity ~5.1 up to ~30.7 kWh
• IP66 rating
• Flexible installation
SolaX Power battery systems are designed using LiFePO₄ (Lithium Iron Phosphate) technology, which is a type of lithium battery known for high thermal stability, low internal resistance, and long cycle life (over a thousand charge/discharge cycles).
These batteries are modular: you can combine several battery modules together to build the capacity you need. For example, 3.6 kWh modules can provide storage in systems up to about 47.9 kWh, and 5.1 kWh modules can form configurations up to about 30.7 kWh.
In these systems, DC Coupled high voltage means that the energy generated by solar panels is transferred directly to the battery (instead of being converted to AC first and then converted back to DC). This architecture has several technical advantages:
• Minimal energy conversion losses between DC to AC and back to DC
• Higher efficiency in stored and used solar energy
• Faster response to household energy demand during peak usage
To intelligently manage energy flow, SolaX systems use a Battery Management System (BMS) that:
• Controls charge/discharge cycles to increase battery life
• Monitors internal temperature and thermal protection
• Optimises energy flow between the battery and the inverter
• Enables fault detection and software updates
Ultimately, compatible inverters with the SolaX architecture appropriately manage the stored energy during night or peak usage hours and deliver it to the consumer. This integration increases solar energy utilisation and the overall efficiency of the system.
Monitoring & Maintenance
Monitoring and managing energy through the SolaX Cloud application and platform is one of the key parts of the battery user experience:
Key features of the SolaX application:
• Real-time viewing of battery charge and discharge percentages
• Display of solar energy production, household consumption, and grid import/export
• Daily, weekly, and monthly reporting for performance analysis and consumption optimization
• Status and fault alerts to prevent potential issues
• Software updates to improve performance
• Remote access via mobile or web portal
This tool helps you analyze energy consumption, battery charge behavior, and system performance, allowing you to optimize based on usage patterns and get the most benefit from your investment in the battery.

Smart Considerations Before Choosing SolaX
• Compatible inverters: Proper operation is only guaranteed with inverters compatible with DC Coupled systems
• Expansion after installation: Adding modules after one year requires approval
• AC Coupling limitation: AC Coupled options for non-SolaX inverters are not available
• Local support: Lack of official offices may limit direct brand support

FAQs
- What warranty does a SolaX battery have?
SolaX batteries in Australia come with a 10-year product and performance warranty. The minimum usable capacity at the end of the warranty period is typically around 70% of the original capacity. - What is the expected lifespan of a SolaX battery?
With normal use, SolaX LiFePO4 batteries last approximately 10–15 years. Charge/discharge cycles and environmental conditions affect the actual lifespan. - What is the usable capacity of the battery?
Depending on the model and number of modules, capacity can range from 4.6 kWh up to around 48 kWh. Typical households often use 9–15 kWh. - What is the maximum output power of the battery?
Output depends on the configuration; smaller systems provide around 2.8–5 kW continuous power, while larger systems offer higher output. - How much space does the battery occupy and what is its weight?
Modules are compact and can be wall-mounted or floor-mounted. Example dimensions: 474 × 193 × 708 mm, weight approximately 72 kg. - Can multiple SolaX batteries be combined?
Yes, SolaX batteries are modular, allowing multiple modules to be combined to increase total capacity. - Does the battery provide backup power during outages?
When installed with a compatible inverter, essential circuits in the home can remain powered during blackouts. Not all systems provide backup by default. - What are the installation requirements to maintain the warranty?
Installation must be performed by a qualified technician and the battery registered on the SolaX Cloud platform. Adding modules after one year requires manufacturer approval. - Is the battery compatible with other inverters?
SolaX batteries generally work with DC Coupled compatible inverters. Using non-compatible inverters is not recommended for proper operation. - How much capacity does the battery lose over time?
Capacity gradually decreases. After 10 years, at least 70% of the original capacity remains, and the battery can still be used for several more years at reduced capacity.
