What types of Lithium batteries should I choose?
Once we are clear that we want to get hold of a Lithium battery for our photovoltaic installation, the next step is to choose which types of Lithium batteries interest me most.
Let’s see what batteries we can find according to their characteristics.
Types of lithium batteries for solar panels
We can classify Lithium batteries into several categories depending on the criteria we apply in each case.
- Depending on the battery voltage.
- Depending on the brand.
- Ferrophosphate and nickel-manganese cobalt oxide batteries.
We are going to analyze the following classifications one by one to better understand the types of Lithium batteries we can choose.
Lithium battery voltage
We can choose between high-voltage (HV) and low-voltage (LV) batteries. Our choice should depend on the inverter that we have in our solar kit, and on the characteristics of the installation. If you have a hybrid inverter, you will need a high-voltage battery.
Because batteries (HV) are more efficient, if you require more consumption due to the nature of your home or industrial company, this type of battery is more recommended.
If you have any questions about your solar installation, you can contact us so that we can help you choose your batteries according to your needs.
There is currently a wide variety of battery brands available on the market. At Cuenca Solar, we recommend brands such as Byd, Huawey, Lg, and above all, the Pylontech brand. The Pylontech brand is one of the best-placed brands in terms of quality/price.
Lithium Ferrophosphate (LFP) and Nickel Manganese Cobalt Oxide (NMC) Battery
LFP batteries are best known for being safe, durable and ideal for household uses. This is because these batteries do not contain cobalt, which is known to be able to catch fire.
They do not need ventilation, so they are the most used in residential places that need daily energy cycles and that are connected to the electricity grid.
NMC batteries, because they contain nickel oxide and cobalt manganese, allow them to store more energy than the rest of the Lithium-ion batteries we have seen. The battery itself contains a management system that monitors the functions of this battery, as is the case with LFP.
We must be careful with extreme temperatures, as exposing them to these situations will reduce their lifespan.
What type of lithium battery do I choose for my solar installation?
Once the different types of batteries have been analyzed, the use of one type of battery or another will depend on several factors.
First we must consider the size of our installation, depending on the solar panels, and the energy we require.
Second, we must know how many electronic devices we want to be connected to the solar installation.
It is very important that depending on the use we are going to give to our installation, we choose the right batteries for each situation. It’s important to take good care of the batteries, if we don’t want to replace the batteries ahead of time.
At Cuenca Solar, we advise you to contact us so that we can advise you in a personalized way according to your needs and your solar installation.
