I have a grid-tied solar system with battery back-up. I use a SolarEdge StorEdge inverter with an LG Chem RESU10H lithium-ion for battery storage. I recently purchased a Tesla Model Y. In using the Electric Vehicle there exists a wealth of videos/information regarding maintaining the health and longevity of the battery. Tesla and many others stress the importance of
only charging the vehicle to 100 % if you are embarking on a long trip. In daily commuter short distance driving we are advised to
only charge the battery to 70-80% maximum!! Using this system of charging we are told will maximized the useful life
of the battery.
As I have come to appreciate this advice , I find myself concerned about the cycling of my solar battery storage system. Should not the battery health advice given for my Tesla also apply to my solar electric storage battery?? My battery currently discharges to 70 or 80% each night, then immediately charges
back up to 100% in the morning.(assuming a sunny day). So......is this charge/discharge cycle unhealthy for the long term health of my battery?? If so, what steps can I take to rectify the situation?
Thank you,
Michael
