LG Chem RESU battery storage supply and installation

The LG Chem RESU Battery Range
The RESU or 'Residential Energy Storage Unit' range consists of both 48 volt and higher voltage 400 volt lithium-ion battery options. The 48V (LV) series is available in 3.3kWh, 6.5kWh, 9.8kWh and 13kWh. While the higher voltage (HV) 400V batteries are available two sizes - 6.5kWh and 9.8kWh. A new Gen3 16kWh high-voltage battery is due to be released late 2020, see full details below.

All size figures are based on the total available capacity (kWh), however usable capacity is limited to 90% for the 48V version, and 95% for the 400V series. For larger residential systems a maximum size of 19.6kWh can be achieved by linking two of the 9.8kWh (RESU10) battery units together using the LG RESU plus battery combiner unit - the RESU plus.

The larger capacity RESU13, 48V battery was released in 2018 in order to compete with the Tesla Powerwall 2 (13.5kWh) battery.

All LG Chem RESU batteries are IP55 weather-rated. This means they can be installed in a semi-outdoor location such as a verandah or carport, but should not be located in a position exposed to direct sunlight, especially during the warmer months. As with any electrical/battery system, excessive prolonged heat is detrimental to the performance and life of the system.

Our certified installers have hands on experience installing numerous LG Chem RESU units across domestic projects.
