Trina have also soft launched their rather well position but (in my view 50%-60%) over-priced solutions - which are Lithium based storage plus inverter - in decent sizes and maximum power out ratings - but at $1,200 USD a kWh they did an oppsie. About $800 a kWh is the target I reckon must be hit for an economical solution.
The one I am really keen of seeing and what price point they hit are the modular 1.2kWh Enphase systems - as I love web based controlled, individually controllable and programmable storage solutions. A system with Enphase micro-inverters on any decent solar panel, plus Enphase storage on the new Enphase Gateway-S would be a killer design in my view. Time will tell as these technologies are now well less than 12 months away.
