Q:
What would your design or feature "wish list" be for this product?
36 answers
Answers:
Mass produced low cost grid-tied macro-inverters (300W to 600W) that can work in remote regions (without conventional grids) with a captive smart-grid. The modular design should permit both consumer and the micro-grid to expand as the energy-needs of such first-timer users grow.
~Gulshan K, Manufacturer, New Delhi, India
Close to true sinusoidal wave production. Consistent performance throughout heat and life cycle. Tolerance for input variations or a compatible external component that will be tunable to specific needs. This would increase the useability of a single DCACi.
