In photovoltaic (PV) distributed generation system, the knee point is how to capture the energy generated by PV array and optimal conversion for achieve maximum productivity of the system. In this paper, re configurable high step up dc to dc converter and re configurable dc to ac inverter suitable for local utility interconnection is presented. Proposed dc to DC to AC hardware is tested under the conditions of different loads with variable standards also at different solar power input. The power fluctuation in the input or output is sensed with WCS 2705 hall sensor, and it’s fed to ultra-low power MSP 430 powerful microcontroller, 200 kHz sampling error signal is reconfigured according to memory setting. Thus, enhanced generated power absorb, optimized loss and higher stability are implemented. Specific real time 2 kilowatt hardware of the proposed feature full controller based dc to dc to ac inverter is presented. The real time hardware implementation results justify the stability and feasibility of the universal load analysis and the proposed hardware topology. Experimental Verification of a Module Integrated Isolated Coupled Inductor based DC-DC Boost Converter fed Micro-inverter.
