Safe Home Battery is essential to you

Safe home battery is essential to you whenever you decide to install a home battery system.

So, why we must choose the best brands and safe home battery (LFP Lithium battery)? Recently a breakout news about a fire accident happened in Northern Adelaide spreads out, and people begin to pay attention to the solar battery safety. No one would like to live with an unsafe battery system, and it would be like living with a bomb that is possible to explode at any time. A complete abandon of solar battery is not smart as it is still a component for a cleaner future. However, it is highly recommended to select the safe and qualified battery brands and models to secure your energy and your property.

For end consumers, Lithium battery may all the same. But actually there are big differences in terms of safety. The safety of a lithium battery is largely determined by its chemistry, including NCA, NMC or LFP. NMC which is better than NCA on safety. But still not the best. The safest chemistry is LFP which is the one Growatt battery using.

Below is a comparison of different chemistries

One of the main causes of danger in lithium-ion batteries is related to the phenomenon of thermal runaway. This is a heating reaction of the battery in use and is caused by the nature of the materials used in the battery chemistry. Thermal runaway is mainly caused by the demands placed on the battery under specific conditions, such as overload in unfavorable climatic conditions. The result of thermal runaway of a battery depends on its charge level and in the worst case may lead to inflammation or even explosion of the lithium-ion battery. However, not all types of Li-ion technology, due to their chemical composition, are equally susceptible to this phenomenon. The following graph shows the energy generated during an artificially induced thermal runaway

As can be seen, among the lithium-ion technologies mentioned above, LCO and NCA are the most dangerous chemicals from a thermal runaway perspective, with a temperature rise of about 470°C per minute.

The NMC chemicals emit about half as much energy with a rise of 200°C per minute, but this level of energy leads to internal combustion of the material and ignition of the battery in all cases.

In addition, it can be seen that LiFePO4-LFP technology is slightly affected by the thermal runaway phenomenon, with a temperature rise of only 1.5°C per minute.

At this very low level of energy release, thermal runaway of LiFePO4 technology is inherently impossible in normal operation, if not almost impossible to trigger artificially.

Combined with a BMS, Lithium Iron Phosphate (LifePO4 – LFP) is the safest Li-ion technology on the market today.

Now a kind of LFP home Battery is your best choice

Fortunately, all of the Growatt batteries use lithium iron phosphate (LFP) technology and already added more safe and reliable consideration for your home battery system. It’s time to know the difference of the chemistries and importance of choose a safe battery. Do not risk their safety just because a big brand.

LFP home batteries have been carefully installed for many homes

There are many solutions from Sunterra for you to select, you can choose to install one home battery or two home batteries, depending on the conditions of your family. They are both safe home battery examples.
