Inverter

The EMPS 5kW inverter is a grid-tied inverter system for North American photovoltaic systems. The inverter provides 120 or 240V AC single phase power at 60Hz. The inverter is designed to meet IEEE1547 and UL1741 standards.

The EMPS inverter has superior efficiency to currently available inverter systems. The 5kW inverter system has proven peak efficiency of >98%. The CEC (California Energy Commission) weighted average efficiency is estimated to be ~98%. The inverter can also be stacked (used in parallel) for use in higher power systems without any loss of efficiency.

The higher inverter efficiency also dramatically reduces wasted heat dissipation. This enables the system to eliminate the active cooling fan and only use natural convection cooling. The lower heat dissipation also reduces thermal stress on components and leads to more reliable long term operation.

The Maximum Power Point Tracking range for the inverter is 350 to 550V DC for high voltage PV string arrays. The inverter, when combined with EMPS' converter can also be used in hybrid systems with low voltage sources such as batteries, fuel cells and low voltage parallel PV arrays.
