The Guardian series is not only the safest, most reliable, and smartest battery storage system on the market but also one of the most price competitive. The Guardian series offers excellent value for money, making it an ideal choice for those looking to maximize the benefits of their off-grid or hybrid solar installation.

Flexibility & ease of Installation

The Guardian Series Battery Storage System is an extremely flexible solution for off-grid and fringe-of-grid solar installations. Its “plug and play” installation makes it easy to install and expand at any time.

With the Guardian, you have the freedom to choose the best inverter/charger platform suitable for your application including Selectronic SP Pro, Victron Energy MultiPlus & Quattro and SMA Sunny Island.

Intelligent

At the heart of each Guardian BSS is Polarium’s smart 12.9 kWh battery module. These batteries are smart devices with the ability to monitor key battery parameters via Bluetooth, direct PC link or supported inverter platforms.

Know in real-time how your battery system is performing with accurate State of Charge (SOC), State of Health (SOH), Current, Voltage and Temperature readings.

The Guardian BSS can be configured as a ‘managed’ or ‘non-managed’ battery based on chosen inverter platform.

NEW FOR Q3 2023: Guardian will support direct communications with SMA Sunny Island and Victron Energy Inverters to actively manage charge/discharge parameters and remote monitoring via Sunny Portal / VRM Portal.*

Pedigree

Solar Energy Australia is proud to be bringing battery technology to the market via the Guardian Series that previously only available to Industries that demand products that can perform under the toughest conditions.

Polarium smart lithium batteries are the lithium-ion battery of choice for Australians:

• Telecommunications providers 
• Government and Public Safety Agencies 
• Railway Networks 
• Defence Infrastructure    

Reliability

The Guardian Series Battery Storage System is designed and tested for Australian conditions, making it an extremely reliable energy storage solution. With its integrated pre-charge circuit, wide temperature operation, advanced battery management system (BMS), and robust construction, it offers unmatched performance and durability all backed by a comprehensive 10 Year warranty.

• No requirement for weekly maintenance charge to 100% SOC to support cell balancing.
• Polarium’s patented Current Limiting Device (CLD) prevents over-charge and over-discharge without disconnecting/disabling the battery. Allows batteries with different SOC to be installed in the same system.
• Battery system can be easily ‘black started’ – by applying voltage to the terminals.

Safety

The Guardian Series is a ‘plug and play’ pre-assembled battery system that is compliant with AS 5139 installation requirements and the CEC’s ‘Best Practice Guide’
At the core of all Guardian models is the Polarium SLB48-250-146-2 battery module. These battery modules benefit for 5 Layers of embedded safety protection, including the most sophisticated Battery Management System (BMS) available on the market today.

Lithium-ion batteries are an extremely powerful and their high energy characteristics can pose a risk if not managed correctly.

Too often the safety discussions are oversimplified with a debate on cell chemistry alone, and not the multiple layers of protection that make a safe and reliable product.
