What is a Solar Inverter?

A solar inverter is a critical component of a solar energy system. Its primary function is to convert the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity that can be used to power homes and businesses or fed back into the electrical grid. Solar panels produce DC electricity when exposed to sunlight, but most household appliances and the electricity grid operate on AC power. The solar inverter bridges this gap by converting the DC electricity into AC electricity, which is compatible with standard electrical systems.

Solar Inverter Explained

Here are the key functions and features of a solar inverter:

DC to AC Conversion:

  • Conversion: Solar inverters use electronic circuits to convert the variable DC output from solar panels into a stable and synchronised AC output, which is suitable for household and grid-connected use.

Maximising Energy Harvesting:

  • Maximum Power Point Tracking (MPPT): Many modern solar inverters employ MPPT technology to optimise the efficiency of the solar panel system. MPPT allows the inverter to adjust the electrical operating point of the modules to ensure maximum power output, especially under varying weather conditions.

Grid Connection:

  • Grid-Tied Systems: Solar inverters in grid-tied systems are designed to synchronise the solar-generated AC electricity with the utility grid. This allows excess electricity to be fed back into the grid, often earning credits or compensation through net metering programs.

Safety Features:

  • Anti-Islanding: Solar inverters have safety features like anti-islanding, which ensures that the inverter shuts down during power outages. This prevents the solar system from continuing to feed electricity into the grid, ensuring the safety of utility workers working on the power lines.

Monitoring and Data Collection:

  • Monitoring: Many solar inverters come with built-in monitoring systems that allow homeowners and solar installers to monitor the performance of the solar panels. This data helps in identifying issues promptly and optimising the system’s efficiency.

Types of Solar Inverters:

  • String Inverters: These are common for residential and small commercial installations, where several solar panels are connected in series to form a “string.” A single inverter is connected to multiple strings.

  • Micro inverters: Micro inverters are small inverters attached to each solar panel individually. They operate independently, allowing each panel to perform at its maximum capacity regardless of shading or panel mismatch.

  • Power Optimisers: Power optimisers are devices connected to each solar panel, optimising the DC electricity output before it reaches the inverter. They work in conjunction with a string inverter.

We have listed the best solar inverters for use in Scotland below.

Solar inverters are a crucial component of solar energy systems, ensuring efficient energy conversion and integration with the electrical grid. The choice of the type of solar inverter depends on the specific requirements and design of the solar installation.
