Extending the Lifespan of Your Must and Meritsun Solar Batteries (Up to 50%!)

At Sona Solar Zimbabwe, we are committed to helping you get the most out of your solar investment.


A key component of any solar system is the battery, and its lifespan directly impacts your overall system performance and cost-effectiveness. Here, we explore practical tips to maximize the lifespan of your Must or Meritsun Lithium-ion (Li-ion) solar inverter battery, potentially extending its life by up to 50%!

Understanding Li-ion Battery Technology:

Li-ion batteries are the preferred choice for solar systems due to their superior performance, lightweight design, and long lifespan. However, like any battery, they have a limited number of charge cycles.

By implementing these practices, you can significantly improve the health and longevity of your Must or Meritsun battery.

Insights from Mercury Direct

  1. Maintain Optimal Depth of Discharge (DOD): DOD refers to the percentage of a battery's capacity that's used during a discharge cycle. Ideally, aim to keep your DOD between 10% and 80%. Completely draining your battery (0% DOD) or routinely letting it drop below 10% can significantly reduce its lifespan. Must and Meritsun batteries often come with built-in features to prevent excessive discharge.
  2. Avoid Extreme Temperatures: Both Must and Meritsun Li-ion batteries are designed to operate within a specific temperature range. Excessive heat can accelerate battery degradation. Ideally, aim for an ambient temperature range between 15°C (59°F) and 25°C (77°F) for optimal battery performance and longevity. Consider ventilation strategies in your battery enclosure to manage heat, especially in direct sunlight.
  3. Minimize Charge Cycles: The number of times your battery goes through a complete charge and discharge cycle directly impacts its lifespan. Here's how to minimize cycles:
  4. Optimize System Size: Ensure your solar system is sized appropriately to meet your energy needs. An oversized system will lead to more frequent shallow discharges, which can contribute to faster degradation.
  5. Shift Loads: When possible, try to shift non-critical energy consumption to daylight hours when your solar panels are generating electricity. This reduces reliance on battery discharge cycles.
  6. Regular System Monitoring: Sona Solar Zimbabwe recommends routine monitoring of your solar system's performance, including battery health. Both Must and Meritsun batteries likely have built-in monitoring systems or are compatible with monitoring devices that track factors like voltage, current, and temperature. Regular monitoring allows you to identify potential issues early and take corrective action to prevent long-term damage.
  7. Preventative Maintenance: Schedule regular preventative maintenance for your solar system with a qualified technician. This includes cleaning the battery compartment to remove dust and debris and ensuring proper ventilation. A technician can also check for any loose connections or signs of corrosion that could impact battery performance.
