The need for an uninterrupted power supply cannot be over emphasized. Solar energy is one of the cleanest and renewable sources of energy available. However, it comes in form of direct current while most of the electric devices are designed to operate on alternating current. Hence this work concerns the design, construction and analysis of 1000 VA inverter powered by a solar panel via a 12 V industrial battery. The solar panel is made to charge the battery using a solar charge controller as a regulator. The 12 V DC from the battery is converted to 12 V AC at a frequency of 50Hz using integrated circuits, semiconductors and a power MOSFETs as a switching component. This voltage is then stepped up to a 220 V AC via the windings of a transformer. The circuit is found to be stable when within ±3% of the rated power.
