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.
