Solar Battery – Sealed Lead-Acid and Lithium-ion BMS Batteries

What’s a solar battery and Why do solar energy systems require batteries?

Solar panels have one job – They collect sunlight and transform it into electricity. But they can make that energy only when the sun is shining. Thatโ€™s why the ability to store solar energy for later use is important. It helps to keep the balance between electricity generation and demand. Solar batteries are the way to store this energy.
Simple solar panel systems do not have batteries. But you can also buy hybrid systems that have batteries or are battery-ready.
The batteries store energy for you to use at a later time or to be sent back into the grid at a time that capitalizes on energy prices.
Batteries can also allow you to go off-grid or provide an alternative to joining the grid.
There are different kinds of battery technologies, but the main one currently dominating the market is lithium-ion.

SLA – Sealed Lead-Acid Battery
AGM – Absorbent Glass Mat
BMS – Battery Management System
