It’s currently possible for batteries to be a great investment, but diminishing returns hit hard. The most cost efficient setup is a solar farm where the panels produce DC which directly charges the batteries and the losses from DC>AC conversion only happens once before you send power to the grid. With the added benefit of only paying for a single set of DC>AC equipment.

However, the more such systems come online the less peaking power is worth and batteries aren’t competitive with current ultra low nighttime rates.
