Understanding the risks of solar batteries and how STS ensures safety

As the demand for solar energy grows in South Africa, more community schemes are investing in solar and battery backup solutions to mitigate load shedding and reduce electricity costs. While these systems offer significant benefits, it is crucial to understand the risks associated with solar batteries and how to prevent potential hazards.

At Sectional Title Solutions (STS), we provide expert guidance, maintenance, and safety measures to ensure reliable and risk-free solar energy adoption.

Solar battery storage systems enhance energy independence, but they also come with potential risks if not properly installed or maintained. Here are some key risks and how they can be managed:

While rare, lithium-ion batteries – the most commonly used solar storage solution – can pose fire hazards if damaged, improperly installed, or subjected to extreme heat. Overcharging, deep discharging, or manufacturing defects can also lead to thermal runaway, a condition where the battery overheats uncontrollably.

Prevention measures:

• Ensure professional installation by certified experts, such as those working with STS.
• Use battery management systems (BMS) to prevent overcharging and overheating.
• Keep batteries in a cool, well-ventilated space away from direct sunlight and flammable materials.

Misinformation about solar battery explosions often causes unnecessary fear. While cases of battery explosions are extremely rare, they can occur due to poor-quality batteries, improper handling, or inadequate ventilation leading to gas buildup.

Prevention measures:

• Choose high-quality, certified batteries from reputable suppliers such as ours.
• Implement proper ventilation systems in battery storage areas.
• Regularly inspect batteries for swelling, leaks, or unusual heat buildup.

Lithium-ion and lead-acid batteries contain hazardous materials that can be harmful to both human health and the environment if they leak or are improperly disposed of.

Prevention measures:

• Follow manufacturer guidelines for battery maintenance and disposal.
• Use only authorised recycling centres for expired batteries.
• Avoid physical damage to battery casings.

All batteries degrade over time, leading to reduced efficiency and capacity. Factors such as frequent deep discharges, high temperatures, and poor maintenance can accelerate this process.

Prevention measures:

• Use smart energy management systems to optimise charging and discharging cycles.
• Maintain moderate battery charge levels (avoid complete discharge or overcharging).
• Schedule regular maintenance with STS’s expert team.

Improper installation can lead to wiring faults, short circuits, or poor system performance. Many risks associated with solar batteries stem from inadequate maintenance or a lack of professional oversight.

Prevention measures:

• Only work with qualified technicians, like those at STS, who ensure compliance with safety regulations.
• Conduct routine inspections and servicing to detect issues early.
• Educate homeowners and scheme managers on proper battery usage and storage.

At STS, we recognise the importance of a safe and efficient solar energy system. Our expertise in community schemes allows us to provide:

• Professional installation: Our certified solar partner Bright Light ensures compliance with safety regulations and best practices.
• Regular maintenance and monitoring: We offer ongoing monitoring and scheduled maintenance to maximise battery lifespan and safety.
• Quality assurance: We only work with reputable suppliers, ensuring that all installed batteries meet the highest safety standards.
• Comprehensive risk management: We have extensive knowledge on fire safety measures, proper storage solutions, and emergency response plans.

Solar battery storage is a game-changer for South African complexes, flats and estates, offering resilience against power disruptions. However, understanding the associated risks and taking proactive measures is essential for safe and effective use. With STS’s expert guidance, professional installation, and comprehensive maintenance services, you can harness the power of solar with confidence and peace of mind.
