Solar Inverters

Solar inverters are crucial for converting the direct current (DC) electricity generated by your solar panels into alternating current (AC) electricity for use in your home. The placement of your solar inverter can impact the efficiency and overall performance of your solar energy system.

Things to consider when choosing where to place your solar inverter

Choosing the right location for your solar inverter is a critical decision in the process of setting up a solar PV system for your home or business. The inverter plays a crucial role in converting the direct current (DC) electricity generated by your solar panels into alternating current (AC) electricity that can be used to power your appliances and be sent back to the National Grid. Here are some important factors to consider when deciding where to place your solar inverter:

  1. Proximity to Solar Panels: Ideally, the solar inverter should be located as close as possible to your solar panels. This minimizes energy loss due to long cable runs, reducing voltage drop and increasing overall system efficiency. If you have a string inverter (one central inverter for all panels), it should be placed near the center of your solar array. For microinverters or power optimizers, each one should be placed near its respective panel.
  2. Weather Protection: The inverter should be shielded from extreme weather conditions such as direct sunlight, rain, snow, and excessive heat. Choose a location that offers protection from the elements to ensure the inverter’s longevity and performance. An outdoor-rated inverter enclosure or wall-mounted box can provide the necessary protection.
  3. Adequate Ventilation: Solar inverters generate heat during operation, and they require proper ventilation to dissipate this heat. Ensure that there is adequate airflow around the inverter to prevent overheating. Installing it in a well-ventilated area or adding a fan if necessary can help maintain a suitable operating temperature.
  4. Accessibility for Maintenance: Consider ease of access for maintenance and servicing. Inverters may require occasional maintenance or repairs, so ensure that the chosen location allows for easy access. Avoid obstructing the area with obstacles or placing it in an inaccessible location.
  5. Noise Levels: Inverters can produce some noise while operating, especially if they have fans or cooling systems. If noise is a concern, choose a location that is not too close to living or working areas. Alternatively, you can opt for inverters designed to be quieter.
  6. Security: Inverters can be attractive to thieves due to their value. Consider security measures like installing a lockable enclosure or placing the inverter in a less visible location to deter theft.
  7. Electrical Codes and Regulations: Ensure that the installation complies with local electrical codes and regulations. Different regions may have specific requirements for inverter placement, wiring, and safety measures. Consulting with a professional installer like NXTGEN Energy or electrician is advisable.
  8. Future Expansion: If you plan to expand your solar panel array in the future, consider whether the chosen location can accommodate additional inverters or handle increased electrical load.
  9. Aesthetics: The appearance of the inverter and its placement can impact the aesthetics of your property. Choose a location that minimizes visual impact if aesthetics are a concern.
  10. Monitoring and Communication: Ensure that the inverter location allows for easy access to monitoring and communication devices, such as Wi-Fi or Ethernet connections, to enable real-time monitoring of your solar system’s performance.

Ultimately, the right location for your solar inverter will depend on your specific circumstances, the type of inverter you have, and your local conditions and regulations. Consulting with a qualified solar installer like NXTGEN Energy is crucial to making an informed decision and optimizing the performance and longevity of your solar power system.

Near Your Main Electrical Panel

Solar inverters are typically installed near your main electrical panel, which simplifies the connection to your home’s electrical system. This placement minimizes energy losses and ensures efficient energy distribution.

In a Shaded Area

While it’s important to keep solar panels exposed to sunlight, solar inverters should be placed in a shaded area or inside an enclosure to protect them from direct sunlight and extreme heat. Overheating can reduce their lifespan and efficiency.

Wall Mounting

Wall mounting is a common method for installing solar inverters. Ensure the wall is sturdy, and the inverter is mounted at a convenient height for maintenance and monitoring.

Best locations to install a Solar Inverter

Solar inverters are an essential part of your solar panel system setup, allowing you to convert the direct current (DC) that is produced from your solar panels into alternating current (AC) that can be used by your home or business appliances. Here are some considerations for the best placement of a solar inverter in your home:

Frequently Asked Questions About Solar Inverters

What are the types of solar inverters?

What are the 4 types of inverters? In the UK there are four main types of solar inverters that you can choose from. The four types are string inverters, micro-inverters, hybrid inverters and power optimiser inverters.

What type of solar inverter is best for a solar panel system?

String inverters are the standard for most residential home systems. They work by connecting multiple solar panels into an array (single string on one part of your roof or dual string on multiple parts of your roof) and sending the power to a centralized solar inverter for DC (direct current) to AC (alternating current) conversion that’s compatible with the national grid. String inverters are affordable and efficient.

What size solar inverter do I need for my home?

How do I know what size solar inverter to buy? Your inverter should be aligned with the DC rating of the solar panel system itself. So, if you have a 6 kilowatt (kW) system you will need a solar inverter that is around the 6000 W mark to match it.

Can you run a solar inverter without solar battery storage?

Can I use solar panels and solar inverters without solar battery storage? The answer is yes, if you are connected to the national grid, you can use solar panels and solar inverters without solar battery storage.

What is the life expectancy of a solar inverter?

When do you need to replace a solar inverter? While most solar power inverters come with a lifespan of approximately 5 to 10 years, they do require regular maintenance in order to ensure optimal solar inverter efficiency.

Do solar inverters need maintenance?

Do you have to maintain your solar inverter? A solar inverter requires very little maintenance. Once you make sure it’s properly installed, you simply need to keep it clean. Wipe it free of any accumulating dust, debris, and cobwebs on a regular basis.
