How much will I save?

Like investing in solar panels, there comes a time when you will ‘break-even’, recover your initial investment, and enjoy huge savings.  The LG Chem RESU PLUS series is exceptional value and is expected to pay for itself within 5 years.  This will vary from home to home depending on solar system and battery storage capacity and household power generation and usage.  Your bvim network installer can calculate these savings for you more precisely when they visit your home.  What is clear right now is that any investment you make in solar panels is not fully realised unless you can also store the energy you are creating.  The RESU allows you to do that.

I’m considering buying a solar system. Can battery storage be installed at the same time?

How long does installation take?

On the same day that your LG Chem RESU battery storage arrives at your home, a Clean Energy Council of Australia SPS-accredited bvim network installer will carry out the installation.  Installation for battery storage takes about 3-4 hours depending on your existing solar system and individual requirements.  For complete package installation including solar panels, your installation may take longer and will depend on factors such as your home construction type.  Your RESU installer can give you more information on how long installation will take when they visit your home to finalise the quote.  Your contract confirmation will include an estimation of time needed for your installation.
