DRI

)

Pre-configured Power Solution The multi-terminal DRI is a 10kW inverter uniquely flexible to be more reliable, more efficient, and more cost-effective than currently available inverters. The DRI’s distinctive E-Quad design combined with its split-phase electrical connections make it ideal for residential applications including residential off-grid systems, electric vehicle charging, and small-commercial applications.

Efficient | Maximize energy.Maximize energy and minimize cost.Improves energy conversion efficiency. Programmable power curves and charge profiles also provide enhanced control for generators, AC loads, and batteries.

Applications | Energy StoragePre-installed energy management applications.Optimize local energy usage and costs with pre-programmed applications including peak-shaving, backup power, time-shifting, and frequency regulation.

Flexible | Integrate quickly and easily.Highly programmable and easily integrated.E-Quad Technology allows power routing to the grid, DC energy storage, and dynamic AC loads. Multiple AC and DC terminals are ideal for microgrid and off-grid systems.
