Know About Different Types of Batteries of Solar Storage Device

One of the highest energy devices that utilize solar energy is the solar storage device. Connected with a solar system, this is considered an effective device that reserves or stores the energy for making later applications. The energy that is stored in the device is consumed when the sun gets down and when the energy demand rises in case of a power outage. It comes with excellent features including scalable and flexible attributes. In addition to this, this device is ideal to be used in both commercial and residential buildings.

Four main types of batteries

In this storage device, a number of batteries can be used in order to ensure proper functioning and energy storage. Here is a summary of the different types of batteries of the solar energy storage device. Let’s have a look at them in a discreet manner:

Lead-Acid battery

This is one of the practical battery technologies that are well suited for the storage of solar electricity. It is almost the same type that you usually use in your cars. Lead-acid batteries come with a feature of the lowest self-discharge rate among all the rechargeable batteries of the device. Therefore, it is considered an inexpensive battery for energy storage purposes.

One of the most important features of this battery is its capability of discharging high currents. It is a good option to use if you want to store energy on a low budget. Their limited life cycle can be lowered down with repeated deep cycling. Lead-acid batteries are heavy in structure because of the materials used in it. Let’s have a look at some of the positive aspects of this battery:

  • One of the important benefits that come with the application of this is low maintenance requirements.
  • This battery is high performing in terms of working capabilities.
  • It has the ability to withstand overcharging of the solar storage device.
  • Lead-acid batteries ensure low self-discharge because of which it is considered as the lowest among rechargeable batteries. Apart from this, it also provides high performance even at low temperatures.

Lithium-ion battery

Lithium-ion batteries are widely used for large scale solar battery storage applications and for the foreseeable future. When it comes to benefits, you will get to see a long list of this battery. In solar energy stored devices, there are four types of lithium-ion batteries that are used. These include Lithium Manganese Oxide, Lithium Nickel Cobalt Aluminum Oxide, Lithium Nickel Manganese Cobalt Oxide, and Lithium Iron Phosphate. All these batteries are having a high energy density. Generally, the lithium-ion battery requires low maintenance which makes it suitable for solar stored devices. Some of these benefits of Lithium-ion battery include:

  • The rate of self-discharge of this battery is much lower than many other rechargeable batteries.
  • There are some rechargeable batteries that need to be primed after receiving the first charge. But, you don’t have to worry about when you are making use of lithium-ion batteries.

Redux Flow batteries

This kind of battery is comparatively new as compared to other rechargeable storage batteries. It is having a water-based solution that consists of zinc-bromide. Because of this solution, it is known as a flow battery. The main reason for the application of this battery in the solar storage device is its great design flexibility. It also ensures more power output capacity and storage capacity. The water-based solution inside the flow battery acts as a natural fire retardant.

VRLA T Gel battery

Another important battery that you can use in the solar energy storage device is the VRLA T Gel battery. It mainly contains acid which is gelled by adding silica gel. The addition of silica gel turns the acid into a solid mass like jelly. This battery system is specially designed for eliminating gas emission from the devices. Because of its gel-like design, it is leak-proof and it won’t leak even if there is a crack.

Which battery to choose for the storage device?

Every battery has its own pros and cons and is capable of storing solar energy for later consumption. Right from low maintenance to self-discharge, you can see multiple reasons for choosing these rechargeable batteries. On making a comparison and checking out the features & benefits, you can choose which battery is suitable for the solar device applications.
