Solar batteries can improve the efficiency and functionality of your solar power system, but they also increase the cost of installing the system in the first place. In order to get the highest ROI from this added cost, you want your batteries to last for as long as possible. Luckily, there are a few things you can do (or avoid doing) in order to improve the lifespan of your solar batteries. Keep reading to learn what they are.
Avoid Over-Discharging
One of the most common drainers of solar battery life is over-discharging. All batteries have a limit on how much of their power they can discharge. This is called the DoD, or depth of discharge rating. Discharging a battery below this recommended limit can cause irreversible damage to your battery’s cells. A battery’s DoD can vary between 50% and 90% depending on the battery type, with a select few having a DoD higher than 90%. Make sure you know what your batteries’ limits are, and ensure that their discharge level stays within these limits so you can reduce stress on the battery and prevent premature wear.
Use Good Charging Practices
Ensuring your batteries are consistently and correctly charges is also essential to a long lifespan. Batteries should be charged regularly to prevent them from staying at low charge levels for extended periods of time;prolonged storage at these lower charge levels can damage the batteries. Make sure your solar system’s inverter or charge controller is set to follow the specific charging required by your battery type. Many systems include settings to monitor and prevent overcharging, which can be especially helpful.
Avoid Extreme Temperatures
Extreme temperatures can drastically reduce solar battery life. Lithium-ion and lead-acid batteries perform best in moderate climates, typically between 68 and 77°F. High heat can lead to electrolyte evaporation in lead-acid batteries, while extreme cold can limit battery performance. For homes in areas prone to extreme heat or extreme cold, consider installing your battery bank in a climate-controlled environment to maintain stable temperatures. A basement or insulated garage usually works well for this.
Perform Routine Maintenance
In general, a solar power bank can continue doing its job with little to no interference from you. However, if you really want your batteries to last, and you want them to keep performing at peak efficiency during that time, then routine maintenance can help. If you have flooded lead-acid batteries, check electrolyte levels regular to prevent cell damage. For all battery types, clean battery terminals to prevent corrosion and periodically check your connections to make sure they’re secure. All battery types can benefit from a quick visual inspection as well, looking for signs of swelling, leaks, or unusual heating.
