LG Chem Battery
The LG Chem RESU 6.4 EX Lithium-ion battery is a premium quality and versatile battery. The main battery unit features 6.6kWhs of storage capacity and can be expanded with two 3.2kWh modules – allowing you to have 6.4 kWhs, 9.6kWhs or 12.8kWhs of energy storage system. One of the best features of the LG Chem battery is its high power output – up to 5kW peak and 3.5kWs continuous as its cycle life being rated at greater than 6000 cycles. The LG Chem Battery features a round trip efficiency of 95%. Configured correctly with an SMA Sunny Island inverter and Automatic Transfer Switch (ATS), the LG Chem battery also works in ‘offgrid mode’ and can provide blackout protection. The LG Chem battery is best suited for larger capacity energy storage systems and for when blackout protection is required.
Tesla Powerwall Battery
Autonomous Energy will be offering the Tesla Powerwall battery just as soon as it is available in Australia. The Tesla Powerwall comes in 10 kWh weekly cycle and 7 kWh daily cycle model. In reality it’s only the 7kWh model that’s useful for Australian residential energy storage requirements. Multiple batteries may be installed together for homes with greater energy need, up to 63kWhs total for the 7kWh battery. The Powerwall requires a separate battery inverter. The Powerwall has a round trip efficiency of 92%, power output of 3.3kWs and a 10 year warranty.
NeeoQube and NeeoSystem Battery
The NeeoSystem is the most highly spec’d Lithium-ion battery on the market. Manufactured in Germany by Akasol, the NeeoQube and NeeoSystem offers exceptionally high power output, safety, reliability and quality. The NeeoSystem comes in 5 different configurations from 5.5kWhs to 27.5kWhs. Configured correctly with an SMA Sunny Island inverter and Automatic Transfer Switch (ATS), the NeeoQube and NeeoSystem battery also works in ‘offgrid mode’ and can provide blackout protection.
