The invention relates to a novel renewable energy generation feedback system, which is characterized in that the novel renewable energy generation feedback system comprises direct current power, an isolation transformer, a plurality of power change modules and a main control circuit, wherein the direct current power is produced by a generation device, the isolation transformer is used to feedback electric energy to a power network, a primary side thereof is a three-phase winding and is connected with the power network, and a secondary side thereof is a multi-channel three-phase winding. The power change modules change direct current to alternating current, the input ends of various power change modules are connected in series and are directly connected with the direct current power or are connected through matching inductance, and the output end of the power module is respectively connected with the secondary side winding of the isolation transformer. The main control circuit is connected with the power change modules, the main control circuit comprises a voltage detection unit and a current detection unit, through detecting the voltage and the current values of the direct current power and comparing with a predetermined value, the work of the power module is controlled. The novel renewable energy generation feedback system has low cost, high reliability, high conversion efficiency and low harmonic content.
