How can solar batteries be recharged? batteries be recharged?

There’s two meanings for the term “solar battery”:

1.A system comprising solar panels for collecting solar energy, and a battery which can store that energy, as well as the electronics that typically links these two (I.e. battery recharger), and perhaps the inverter (more electronics) that connects this system to a mains-wired home/premise. Here, the batteries are charged by the solar panels, though if the inverter is grid-interactive, it could also be recharged from the electricity grid.

2.Batteries designed with the specific characteristics suited to use in applications where solar panels are part of the system storing and providing power. Those battery characteristics are typically to cope with deep cycling, operating for prolonged periods in a partial state of charge, low maintenance requirements.
