Nabu Energy

The sun is a powerful source of clean energy, but its availability can fluctuate throughout the day. This is where battery energy storage (BESS) steps in, acting as your personal solar power bank. It captures the excess energy generated by your solar panels during peak sunshine hours and stores it for later use, ensuring a steady flow of clean energy even when the sun goes down. But how exactly do these batteries work, and are they reliable enough for your long-term solar investment? The Power of Lithium-Ion: Inside Your Solar Battery Lithium-ion (Li-ion) batteries are the undisputed champions of residential solar storage. Here’s a deeper dive into how they work: Electrochemical Reaction : At the heart of a Li-ion battery lies the movement of lithium ions between two electrodes – a positively charged cathode and a negatively charged anode. During charging, electricity flows into the battery, causing lithium ions to de-intercalate from the anode and intercalate (embed) themselves int
