The report presents a physical model of a single-phase hybrid inverter for domestic use up to 12kV. The inverter is designed to be installed beforе the main distribution board, which means that it provides uninterrupted operation to the consumers regardless of whether there is an external network or not. There are additional inputs for rechargeable batteries and solar batteries is not sufficient at the time of peak load, the inverter can compensate for the d power from the power grid. The blocks of the hybrid inverter are mounted in an aluminium box, which ensures the cooling of the traction elements. Each block is built on a separate experimental board, and the individual blocks are connected to each pther on a motherboard. There is diode signaling for the available operating and operating voltages. Network protections are intended to be turned on from outside the devise.
