Important properties are their lifetime (energy capacity decrease after a number of charging/discharging cycles), the amount of energy they can store, the power they can charge/discharge with, and their power/energy ratio, the C rate. The properties of the inverter and the battery chemistry are responsible for all these factors. Currently, mostly Lithium ion batteries are connected to grids. They provide high C rates and less energy capacity decrease per charge cycle than other batteries.

As long as batteries have capacity to charge or discharge, they can do either with any power (up to their maximum power) you need, so they can actually replace your generators, create and maintain a grid, and control their power according to demand. So you can actually turn off those fossil fuel monsters! And by charging, batteries can provide "negative power". Your minimum idling power is now negative, which means you can suck up excess PV power, and feed it back into the grid later!
