On-Grid Solar Inverters

On-Grid Solar Inverters for Grid-Connected PV Systems

An on-grid solar inverter converts the direct current (DC) electricity generated by photovoltaic modules into alternating current (AC) that can be used by electrical equipment in a grid-connected property. These inverters synchronise their output with the electricity grid and are widely used in residential, commercial and larger photovoltaic installations.

Solar electricity generated by the PV system can be used by electrical loads within the property. Depending on the installation, local regulations and electricity supply arrangements, surplus energy may also be exported to the grid.

MPPT and Solar Energy Conversion

Modern grid-connected solar inverters commonly use MPPT (Maximum Power Point Tracking) technology to optimise energy harvesting from connected PV strings as sunlight, temperature and other operating conditions change. Models with multiple MPPT trackers can provide additional design flexibility where solar modules are installed across different roof orientations or PV strings.

Other available functions can include system monitoring, communication interfaces, configurable grid parameters and protection features. Exact functionality varies according to inverter model and manufacturer.

Single-Phase and Three-Phase On-Grid Inverters

Single-phase solar inverters are commonly used for residential and smaller PV installations, while three-phase solar inverters can be suitable for larger residential, commercial and industrial applications. The appropriate configuration depends on the electrical installation, required inverter capacity and applicable grid-connection requirements.

Choosing an On-Grid Solar Inverter

Important considerations include inverter AC output power, maximum PV input power and voltage, MPPT operating range, number of MPPT trackers, efficiency, phase configuration and compatibility with the proposed PV array. Grid requirements and applicable electrical standards should also be considered when designing an installation.
