The system I am aware of was part of a large PV system, so it is impossible to break out the unit costs for just the batteries.

EnPhase is really big in Australia due to their widespread time of use (TOU) metering policies. Load shifting is quite common as net metering is not.

This system has over 500 PV panels and has not had one microinverter failure. Admit it has only been on line for just under two years, but that rate is nothing short of remarkable.

The new EnPhase microinverters (S300) will be available this fall and will support large watt panels in both 60 and 72 cell configurations - and about the size of a smart phone.

A little bird told me that "used" battery packs from EVs will be a snap to hook up to an EnPhase system as it will be open to almost any type of battery back.

Time will tell.
