150 W inverter-an optimal design for use in solar home systems

Single-frequency photovoltaic inverters have been on the market since a need arose to produce AC power from a DC source, probably long before the beginning of PV power systems. With the growth in the PV industry, the need for better, more cost-effective inverters is ever present. Producing an inverter of high quality at a low cost is a challenge. A high quality inverter at high cost cannot compete in the low quality inverter market. Solar home systems are often offered inverters that do not look after the assets of the client, i.e. the lifetime of lights and various loads used on inverters. A investigation was done, looking at various 150 W inverters (law as well as high cost), comparing and evaluating the results. A low cost inverter was then developed that caters for most loads at an affordable price
