What is a solar inverter, and how does it work?

At the heart of every solar panel system, a solar inverter plays a pivotal role in transforming sunlight into a usable form of energy for homes and businesses.

As photovoltaic cells capture sunlight and convert it into direct current (DC), the solar inverter steps in as a crucial component responsible for converting this DC into alternating current (AC). This transformation is vital because most appliances and the electricity grid operate on AC.

Functioning as the intelligent interface between solar panels and the electrical grid, its primary task is to manage the flow of electricity, adjusting voltage and frequency to match the requirements of the grid.

This not only enables the efficient use of solar-generated power but also facilitates the potential for excess energy to be fed back into the grid or stored for later use.

9 best practices to optimise your inverter for maximum solar output

  1. Professional installation

    Collaborating with certified solar panel experts ensures accurate and efficient inverter installation. Professional installers follow industry best practices, minimising the risk of installation errors that could compromise system efficiency.

    Make sure your chosen installers have necessary certifications from organisations such as NICEIC (National Inspection Council for Electrical Installation Contracting). This further ensures that they will adhere to quality standards, guaranteeing a reliable and optimally performing inverter and solar panel system in your home or commercial space.

  2. Regular maintenance

    Routine maintenance is paramount to ensure your solar inverter operates at peak efficiency. Schedule periodic checks by solar panel experts to inspect for dust accumulation, loose connections, or any signs of wear.

    According to a study by the UK’s Energy Saving Trust, regularly maintained solar systems can maintain up to 95% of their efficiency over a 20-year period, highlighting the impact of consistent upkeep on long-term performance.

  3. Proper placement

    Strategic placement of your inverter is crucial for optimal performance. Install it in shaded, well-ventilated areas to prevent overheating, which can hamper efficiency.

    An important study by the Solar Trade Association suggests that maintaining a lower operating temperature can lead to a significant increase in solar panel output, making thoughtful placement a key consideration for system efficiency.

  4. Voltage optimisation

    Fine-tuning voltage settings to match grid requirements is essential for efficient power transfer. Aligning the inverter’s output with grid specifications ensures seamless integration and minimises energy losses during conversion.

    The UK’s National Grid Electricity System Operator emphasises the importance of voltage control for grid stability, underlining its role in optimising overall energy efficiency.

    This is a crucial step for which it is advisable that you rely on expert solar installers in your region. Professionals at Tarven have completed 8000+ solar projects in the South East and London and we boast over 12 years’ experience. Want to learn how we can help? Call us on 020 8087 0216.

  5. Monitoring systems

    Investing in advanced monitoring tools is a proactive measure to track performance and detect abnormalities swiftly. Real-time monitoring allows for timely intervention in case of issues, ensuring continuous optimal operation.

  6. Timely upgrades

    Keeping abreast of firmware and software upgrades is crucial to benefit from the latest technological advancements. Regular updates enhance the inverter’s functionality, improving performance and compatibility with evolving grid standards.

  7. Clean surroundings

    Maintaining a clean environment around inverters is crucial to prevent dust accumulation and overheating. Regularly clearing debris and ensuring a dust-free environment contributes to the overall longevity and efficiency of the inverter.

  8. Battery integration

    Exploring options for battery storage enhances the overall efficiency of your solar panel system by harnessing excess energy for later use. By preventing overcharging or deep discharging, batteries help maintain the optimal operating conditions of the entire system, including the inverter. This, in turn, prolongs the lifespan of the solar inverter.

  9. Weather considerations

    Implementing weather-specific adjustments is vital to account for varying sunlight conditions. By adapting the inverter settings based on weather forecasts, you can optimise energy production and storage.

    The UK Met Office provides reliable weather data, allowing users to anticipate and adjust their solar systems accordingly, ensuring maximum efficiency even during unpredictable weather patterns.
