Cost

Current PV inverter products have high costs due to expensive components and high engineering costs/unit. The component costs of the EMPS inverter solution is lower than existing units of the same power level since the most expensive components (large transformers and capacitors) are eliminated. The cost of these large transformers and capacitors is driven by commodity materials costs such as copper and iron. The EMPS component cost is driven primarily by commercial semiconductor components whose pricing decreases over volume and time.

The cost of current PV inverters is further limited by the high development and engineering cost per model and the large number of models required by the industry. In additional to supporting a wide range of power levels, separate inverter designs are required for 1) grid-tied, 2) grid-tied battery backup, and 3) standalone applications. The EMPS solution supports all these applications with better cost, flexibility and efficiency metrics than existing products. This enables a single hardware design to address a much broader market area. Furthermore the EMPS product can be customized with software enabling a build-to-order manufacturing model with standardized hardware components and final stage software customization.
