Risks of Installing Solar Inverter and Batteries in Attics
In recent years, solar invert or hybrid inverters with batteries have gained popularity as eco-friendly power solutions. However, it’s crucial to consider where to install these batteries to ensure optimal performance and safety.
In this article, we will explain why it is not advisable to place solar invert or hybrid inverters with batteries in attics in the United Kingdom. We will discuss the dangers of this choice, including temperature fluctuations, limited ventilation, fire hazards, restricted accessibility, overheating of DC cables, and high resistance risks.
Attics in the United Kingdom are subject to extreme temperature variations throughout the year. These fluctuations can significantly impact the efficiency and lifespan of solar invert or hybrid inverters with batteries. Exposure to extreme heat or cold can seriously affect their performance.
Installing inverters and batteries in attics means subjecting them to these harsh temperature extremes, which could ultimately reduce their effectiveness and longevity.
Ventilation and Airflow
Attics often lack proper ventilation and airflow, leading to stagnant air and increased humidity levels. Solar invert or hybrid inverters with batteries generate heat during the charging and discharging. Therefore, it is essential to have proper air circulation to eliminate any fire hazards.
Placing them in poorly ventilated attics can lead to heat buildup, potentially causing thermal runaway. Adequate ventilation is essential for dissipating heat and maintaining the batteries at optimal operating temperatures.
Safety should always be a top priority when dealing with battery systems. Placing solar inverter or hybrid inverter with batteries in attics increases the risk of fire hazards. Attics commonly contain flammable materials like insulation, wood, or stored items, which can fuel a fire.
In case of a battery malfunction or a thermal event due to unfavourable conditions, a fire may ignite rapidly and spread throughout the attic space. To minimise potential risks, it is essential to install batteries in a more controlled and fire-safe location.
Overheating of DC Cables
Attic installations can lead to the overheating of DC cables. Attics often lack proper insulation, and the heat generated by the batteries can cause the DC cables to reach high temperatures. Overheated cables result in increased resistance, leading to power losses and reduced battery system efficiency.
High Resistance Hazards
Installing solar invert or hybrid inverters and batteries in attics introduces additional risks associated with high resistance. High resistance in these components can lead to voltage drops, power losses, and potential hazards, including electrical fires or damage to the battery system.
While solar string inverters or hybrid inverters with batteries offer many advantages, careful consideration of their placement is vital to ensure optimal performance and safety. Attics in the United Kingdom are not suitable for housing these solar string inverters and batteries due to temperature fluctuations, limited ventilation, fire hazards, restricted accessibility, overheating of DC cables, and the risks associated with high resistance.
To guarantee the longevity and efficiency of your battery system while prioritising safety, it is strongly recommended to explore alternative locations. These alternative locations should provide appropriate temperature control, good ventilation, and easy accessibility for regular maintenance and monitoring. Placing solar inverter or hybrid inverter and batteries in a more suitable location can significantly enhance their performance and ensure the safety of your home.
In contrast, you can choose a microinverter instead of a string or hybrid inverter to eliminate the fire risk, overheating of cables, ventilation & airflow issues and extreme temperature fluctuation. Read a detailed comparison of microinverters with string inverters in one of our blogs.
Always consult with a qualified professional to determine the best placement for your specific needs, and enjoy the benefits of sustainable and reliable power solutions.
