While lithium-ion solar batteries have superior longevity, like any product their performance will gradually decline over time. As the battery charges and discharges during normal use, its capacity will naturally reduce after many years. But if your usage is in line with optimum cycling specifications and your battery is well maintained, it can last for up to 15 years.
It’s important to remember though, that even when the chemistry is performing perfectly, a solar battery can be affected by external forces like environmental stress and animal interference. Taking a few minutes to physically check your battery can make a difference. Let’s look at some of the ways you can ensure that your battery continues working for you at peak performance, whatever the weather.
Keep your battery cool
Your solar battery will perform at its best when installed in a cool, dry place. This can be outside under cover and out of direct sunlight, or in a garage or basement if you need to minimise the effects of high humidity, salt-air, or dust outside. You may need to ensure minimum ventilation requirements are met according to Australian Standards. The battery should be kept between 0°C to 45°C for optimal performance. A high-quality battery should include a battery management system (BMS) to provide in-built high and low temperature protection, switching the system off when suffering from extreme weather to save the battery cells from damage.
A maintenance check saves money
Extend the life of your solar battery by giving it a quick check every six months to ensure any maintenance issues are addressed. First, check your LED screen display to make sure all batteries are working. The current and odometer readings should be of similar values (within +/- 5% of each other).
Ensure your battery is still in an open space with adequate ventilation, and clear away any animal nests, insects, or obstructions that may have appeared around it. Check that your connections and cables are still undamaged and fitted securely.
Reward yourself with a reputable provider
Don’t let a broken promise let you down. When you need support, your solar battery provider should be there to offer you expert help. Choose a company (preferably Australian!) that is committed to continually improving the features and quality of their products so you can be sure they are exceeding the standards set by the applicable statutory and regulatory requirements. Even better – help safeguard our environment by ensuring they are listed and approved by the Clean Energy Council of Australia.
With a bit of research to find the best solar battery for you, and a little ongoing care and maintenance, your investment in energy storage will be lighting your home for years to come.
RedEarth Energy Storage provides a 10-year warranty that its batteries will retain 80% of initial capacity, or until it reaches a specified minimum energy throughput – whichever comes first.
