Depending on your family’s energy use, you may need a system that generates more or less electrical power. Ensure that your system will generate enough electricity during the day and, if desired, enough.
[pdf] 3-phase string inverters perform power conversion on series-connected photovoltaic panels. Usually, these inverters are rated around a few kilowatts up to 350 kW. In general, most inverter designs are transformerless or non-isolated. String inverters typically rely on two-stage power conversion.
[pdf] Here I have explained about a couple of simple circuit configurations which will convert any low power inverter to a massive high power inverter circuit. You'll find a plenty of small and medium sized inverter.
