It's not relevant what source is used to charge the batteries. Right now there is a massive price difference between peak and off peak power (partly due to renewables daily cycle), so anyone able to build a battery can charge at the off-peak rate and sell at the peak rate every day. This means that batteries have a revenue source right now, and therefore, the only reason they don't exist is because the cost exceeds that revenue source.

Original producers of energy will have their own storage, and prices will level out. Excess generation capacity (e.g. noon) after recharging storage will be devoted to synthesizing liquid fuels and desalination, which serve unlimited demand. By the time there is enough renewable generating capacity to charge storage, storage will be very, very cheap. Right now, it costs more, so money produces much better results building generation capacity and factories for storage. As the factories are completed, production ramps up, and costs fall.
