Off-grid solar batteries are excellent for ensuring your energy independence. When paired with a solar system, they can minimise your electricity bill while keeping the lights on, no matter what might befall the grid.
You need batteries you can count on. In most off-grid scenarios, lithium-ion batteries are the preferred option. Let’s take a look at why:
Longevity
Lithium-ion batteries are known to have a much longer service life than other types of batteries, such as lead-acid batteries. Their extended lifespan, which allows them to endure between 3,000 and 5,000 charge and discharge cycles, translates to a lifespan of between 15 and 20 years, depending on how often they are used.
In contrast, lead-acid batteries only last about a quarter of this length.
Lithium-ion batteries can also be discharged more deeply without damaging their lifespan, allowing them to be safely discharged to up to 80% to 90% of their capacity without impacting their reusability. This leads to fewer replacements over time and a more stable product overall.
The lithium-ion phosphate chemistry inside lithium-ion batteries is also less prone to degradation and capacity loss than other battery technologies, which is another reason why they last so long.
Safety
Lithium-ion batteries in off-grid solar systems come equipped with a sophisticated battery management system (BMS) that helps to ensure the battery operates at peak performance.
The BMS ensures safe operation by managing the charge and discharge rates, preventing overheating and balancing voltages. Thermal management is also integrated into the BMS to ensure optimal operating temperatures and reduce the risk of uncontrolled chemical reactions that can cause fires or explosions in lesser batteries.
Various other built-in protections are also in place, ranging from overcharge protection to over-discharge protection and even short-circuit prevention. This improves the safety, reliability, and longevity of the battery and helps to prevent any hazardous situations from arising, making lithium-ion batteries a safe option for placement in your home.
Reliability
The long lifespan and stable chemistry of lithium-ion batteries ensure that they provide stable and reliable performance over a long period of time across a wide range of temperatures and conditions. Other types of batteries might be negatively affected by different weather conditions, but lithium-ion batteries remain stable despite temperature fluctuations.
In general, lithium-ion batteries boast a higher energy density compared to other kinds of batteries, which means they are able to store more energy in a lighter and smaller package. This helps you maximise weight and space usage.
The low maintenance nature of lithium-ion batteries means that they can be relied on over a long period of time without ever having to worry about running equalisation charges or performing other maintenance tasks that lead-acid batteries generally require.
