LG Chem RESU (Next Generation)

Featuring a sleek design and powerful performance, LG Chem’s new generation energy storage system has arrived.

Five new LG Chem RESU (residential energy storage unit) models are now available to meet customers’ varying needs with respect to voltage and capacity.

The RESU comes in three low-voltage battery systems (48 volt) at 3.3kWh, 6.5kWh and 9.8kWh. Two high voltage (400 volt) systems are also on offer at 7kWh and 9.8kWh.

With the RESU Plus expansion kit, all 48V models can be ‘cross-connected’ with one other 48V unit of any capacity. This allows the RESU range to offer energy storage capacities from 3.3kWh to 19.6 kWh.


  • World-leading lithium-ion battery technology
  • Compact and light weight
  • Powerful performance: World best energy density
  • Easily adaptable energy storage solution

  • BMS (battery management system) firmware can be updated easily by using SD card


  • Charge during off-peak times – Discharge during peak times
  • Store solar energy generated from photovoltaic panels for future use
  • Discharge during a blackout, functioning as backup power


LG Chem RESU 3.3, 6.5 & 9.8

The RESU comes in three low-voltage battery systems (48 volt) at 3.3kWh, 6.5kWh and 9.8kWh.

With the RESU Plus expansion kit, all 48V models can be ‘cross-connected’ with one other 48V unit of any capacity. This allows the RESU range to offer energy storage capacities from 3.3kWh to 19.6 kWh.

With LG Chem, PV system owners can use PV electricity for their own requirements, not only during sunlight hours but also at times of less light, such as in the morning or evening. Electricity produced by the PV system can be consumed directly, stored in the batteries or fed into the public grid. Self-consumption is prioritised; grid power will only be used when neither the PV system nor the batteries are able to supply sufficient electricity.


LG Chem RESU 7 & 9.8

The RESU also comes in two high-voltage (400 volt) systems at 7kWh and 9.8kWh.

The new systems are lighter and smaller than their predecessors and have been designed to allow easy wall-mounted or floor-standing installation for both indoor and outdoor applications.

Reposit Power

Care Solar Solutions is a proud installer of energy optimisation software Reposit Power.

Reposit learns, adapts and predicts your energy usage to ensure you get the most from your solar, save money on your power bill and pay off your battery faster.

Reposit can even sell your power back to the grid when the prices are highest – earning you GridCredits and an even lower energy bill.

Reposit is like your own energy stock broker. If the demand is high enough, it will automatically trade your excess energy for GridCredits™ which it will then put towards lowering your bill – and every GridCredits you earn is another dollar off your bill.

To access GridCredits you will need to be with an energy company that offers a GridCredits plan.

With Reposit you’re only connected to the grid when you have to be and when energy prices are at their lowest.

Thanks to cleverly designed algorithms, Reposit can predict cloudy weather in your area and pre-emptively charge your battery harder during low cost times.

Reposit is constantly looking ahead, planning the best way to use or store the solar energy, based on predictions of how much is likely to be generated and the home’s typical electricity use.


  • Compatible with single phase, two phase and three phase sites
  • Compatible with all solar inverters
  • Compatible with battery inverters and batteries: Solax, Sungrow, SMA Sunny Boy Storage

Energy saving downlights

By installing LED lamps and fittings, or replacing your home’s traditional incandescent and halogen lamps, your home will use less energy. Good quality LED (light-emitting diode) lighting products produce similar light output to traditional incandescent and halogen lamps and reach full brightness without the need for warm-up time. The lifespan of LEDs has also been proven to eclipse that of incandescent light bulbs, and many fluorescent lamps.


  • Downlight
  • Module
  • Spotlight
  • Global bulb
  • Reflector light
  • T8 tube
  • Panel light
