Affordable lithium battery from the world's largest manufacturer

LG Chem RESU 6.4EX Battery

The new ultra-compact, lightweight LG Chem RESU 6.4 EX is an aesthetically pleasing battery storage solution for any home or business. The 6.4kW battery has an impressive lifespan of 6,000 cycles and a depth of discharge rating of 90% giving a total of 5.76kWh’s of useable storage. Installing a quality LG Chem RESU 6.4 EX battery system will enable your home to be much more energy independant and will also ensure you self-consume as much of your solar energy as possible.

The LG Chem RESU 6.4 EX is currently compatible with the following solar hybrid inverter / chargers:

  • Sungrow SH5K – integrated solar inverter and battery charger
  • SolaX X-Hybrid – integrated solar inverter and battery charger with emergency power facility
  • SMA Sunny Island – add-on unit for existing solar power systems that already have an SMA inverter.

You can easily monitor the performance and health of the batteries and the amount of power being fed into batteries / grid by viewing the LCD screen on the front of the battery inverter or if you have a Sungrow SH5K hybrid inverter you can download the Sungrow SolarInfo Moni free app for your smartphone or tablet.

These are actual screenshots taken from the Sungrow SolarInfo Moni app from a system Sunworks Solar installed here on the Sunshine Coast.

If you prefer not to use the app then you can see data on the performance of your system by looking at the front screen of the inverter. This screenshot of the system we installed on the Sunshine Coast shows power production for the 6kW solar array of 2,658 watts (a very overcast day) of which 1,792 watts is being used to charge the battery,866 watts is being self-consumed by the property and 0 watts being exported to the grid.

During times of higher power consumption in the home or at night the power stored in the battery will be used to meet the household load with additional power, if required, coming from the grid. In this screenshot you can see that the solar array is producing 999 watts whereas the household load is 2,072 watts therefore the battery is supplementing most of the additional power required with only 54 watts being drawn from the grid.
