Solar-Plus-Storage 101

A megawatt-hour (MWh) is the unit used to describe the amount of energy a battery can store. Take, for instance, a 240 MWh lithium-ion battery with a maximum capacity of 60 MW. Now imagine the battery is a lake storing water that can be released to create electricity. A 60 MW system with 4 hours of storage could work in a number of ways:

How home battery storage works

Solar panels generate energy in the form of direct current (DC) electricity. Home battery systems store energy as DC electricity. As most homes run on alternating current (AC) electricity, the DC electricity from solar panels or home batteries needs to be converted. Inverters are the mechanism that safely converts household electricity to AC.
