How To Choose The Right Solar Backup Battery System For You

Investing in solar panels is a great step towards a cleaner future. Many people want to know how to get the most out of their panels and there is one simple answer: a solar backup battery system.

Solar batteries allow you to store any excess energy that you have generated and use it at a later time. This not only saves you money but also reduces your dependence on the grid.

How Do Solar Battery Systems Work?

During sunlight hours, solar panels generate energy that powers the home. A household can rarely use all of the energy that is produced during the day. That is where batteries come in. Storing this excess energy means that your house can be fully powered when you need it most, usually throughout the evenings and nights.

If your battery is fully charged and your panels continue to produce energy, your system will automatically send the leftover electricity back to the grid.

Types of Solar Batteries

Solar battery systems use deep cycle batteries. This means the battery is designed to produce a steady output over a long time. Deep cycle batteries are often used in cars and other large appliances.

Lithium ion and lead acid batteries are currently the most common on the market. Both have their advantages and disadvantages making them suitable for different needs.

Sealed Lead Acid Batteries

There are two types of lead acid batteries: Gel and Absorbent Glass Mat (AGM).

Gel batteries have a lower charge and output rate meaning that they take longer to charge but last longer.

AGM batteries are the cheaper alternative and work better with a larger temperature range.

Both types of batteries have been reported to overheat if they are charged too quickly. This is one of the reasons that extensive research was undertaken into finding a safer alternative, such as lithium ion batteries.

Lithium Ion Batteries

Lithium batteries are the more expensive option however they can last up to four times longer than lead acid batteries. With fewer replacements and maintenance required, the upfront costs pay themselves back.

Batteries made of lithium also have a higher discharge and recharge rate making them quicker and easier to use.

At BLUETTI, we are reconsidering the way we produce electricity and are searching for more sustainable methods than conventional nuclear and coal power. Our batteries rely on renewable energy, like solar, to reduce our carbon footprint.

All our batteries, including the EP600 & B500, use LiFePO4 batteries to ensure reliability and unparalleled safety. Our EP600 boasts a base capacity of 9,920Wh that can be stacked up to 79,360Wh. Compatible with new and existing solar systems, it has never been easier to integrate into your life.

We offer installation and delivery of your products and if you¡¯re not happy, we grant a 10 year warranty to fix any of your concerns.

Benefits of Solar Battery Systems

Investing in a solar backup battery system can help you on your journey towards renewable energy. Not only will it allow you to utilise all of your generated power, but it can also save you money. The more you rely on solar energy, the less energy you are taking from your utility provider. With the right solar system for you, you can generate enough energy to cover all of your electricity bills. This also allows you to become completely independent from the national grid.

Having the security of a battery system can also provide you with peace of mind. You¡¯ll no longer need to worry about power outages, making it ideal for people in areas with unpredictable weather and long lasting blackouts.

Let¡¯s not forget the environmental benefits. Using your generated energy reduces your carbon footprint. When relying on the national grid and other utility suppliers, carbon emissions are sent out to the atmosphere through burning fossil fuels. Choosing to turn to solar means that you leave less of a negative impact on the environment.

What To Consider When Choosing A Battery System

Before purchasing a battery, there are 4 main things to consider.

Price

All batteries range in price depending on the battery type, power output and capacity. Prices usually range from €300 to €3500 but remember to look past initial costs when purchasing as these may pay back quicker. More expensive batteries will require less maintenance and replacements.

Battery Capacity

The capacity of a battery measures the amount of energy that a battery can store. It is typically measured in watt hours (Wh).

Capacity does not always equal the amount of power that the battery can harness as this is altered by output.

Cycle Life

A battery¡¯s lifecycle indicates the number of charges and discharges the battery can provide before capacity begins to deplete. Check out the Depth of Discharge (DoD) before purchasing, as this refers to how much of the battery¡¯s power you can use; a higher DoD means more capacity.

Voltage

Before choosing your battery, ensure it is compatible with your solar panels. If you choose a higher-voltage battery, you may be able to reduce system costs.
