What Are Grid Outage Batteries? And Should You Use Them?

We have long spoken of the advantages of installing a solar battery as part of your solar PV installation. They help you maximise your power generation and allow you to use renewables when your solar panels aren’t generating, such as at night. However, there’s a new kid on the block. Today, we're delving into the world of grid outage batteries, exploring their benefits and applications for both residential and commercial properties.

What are Grid Outage Batteries?

Grid outage batteries, also known as backup batteries or energy storage systems, are essentially rechargeable batteries that store excess solar energy generated by your photovoltaic (PV) system. They work in the same way as regular batteries but can operate in case of a complete outage. When the grid goes down, these batteries provide a power source for your home or business, ensuring uninterrupted operations and keeping your essential appliances running.

You may think that your solar PV system keeps working in the case of an outage but unfortunately, because it is connected to the grid and can therefore send live power to it, it will shut down in the case of an emergency to protect workers and the grid itself. However, outage batteries can kick in and keep your home or business running.

Why are Grid Outage Batteries Beneficial?

Although in the UK power outages are fortunately quite uncommon, it’s not unheard of for bad weather or emergency work to shut the grid down. If you run a business or perhaps have essentially medical equipment at home, grid outages can cost you money, or worse. Grid outage batteries offer several advantages that can enhance the resilience of your solar PV system, providing peace of mind:

• Protection against Power Outages: Grid outage batteries ensure that your home or business remains powered during blackouts, regardless of the cause. This is particularly crucial for businesses that rely on continuous electricity to maintain operations and prevent costly downtime.
  ‍
  
  
• Enhanced Energy Independence: By storing excess solar energy, grid outage batteries reduce your reliance on the grid, enabling you to generate and consume your own electricity even when the grid is unavailable. This can significantly reduce your energy bills and promote energy independence.
  ‍
  
  
• Environmental Benefits: Solar energy is a clean and renewable source of power, and grid outage batteries further enhance its environmental benefits by reducing your dependence on fossil fuels. 

Are Grid Outage Batteries Right for You?

The decision of whether or not to install grid outage batteries depends on several factors, including your energy consumption patterns, budget, and risk tolerance. If you frequently experience power outages, value energy independence, and are concerned about the environmental impact of your energy consumption, then grid outage batteries may be an excellent investment for you. They may also be a great choice if you absolutely cannot go without power in case of an outage.

Factors to Consider When Choosing Grid Outage Batteries

When selecting grid outage batteries, it's essential to consider the following factors:

• Battery Capacity: The battery capacity determines the amount of energy it can store, which directly impacts the duration of backup power it can provide. Consider your energy consumption patterns and choose a battery capacity that can adequately meet your needs during a power outage. We’ll be able to provide guidance on the right battery for your needs and budget.

• Battery Type: There are various types of grid outage batteries available, each with its own advantages and disadvantages. Lithium-ion batteries are the most commonly used in solar PV systems as they’re reliable, long-lasting, relatively compact and able to hold a significant charge.
  ‍
  
  
• Cost: Grid outage batteries can range in price depending on battery capacity, brand, and features. Generally, the larger the capacity, the more the battery will cost. We’re able to advise you on what you may need given your circumstances and budget.
