Batteries output DC. They need an inverter to be connected to the grid. The inverter needs to choose a phase angle at which to output current and voltage, through something that looks suspiciously like a boost converter. This doesn't have to be quite the same phase as the line, it can "lead" or "lag" in an attempt to push the line phase angle back to what it's supposed to be.
