How to make a power bank inexpensively?

23 March 2024 | Aliaksander Roslikau

Have you ever wondered how to build a low-cost energy bank that not only saves you a lot of money, but also provides security and independence in the event of power cuts? We have prepared this article just for you, in which we will show you how, with the help of an inverter Extralink Bolt create a reliable and efficient energy storage system. We will introduce you to energy banks, explain why it is worth investing in them and show you how to use them in your home or business. With us, you will learn about the power of energy independence!

What is an energy store and what will it be used for?

An energy bank works on a similar principle to a battery, but is much more sophisticated and has a higher capacity. Its main purpose is to store surplus electricity that can be produced in times of low demand and then used when demand increases. In this way, energy banks can help stabilise the power grid, reducing the need for more expensive and less efficient energy sources during peak times.

Energy banks can use a variety of technologies to store energy, including lithium-ion batteries, flow batteries or even energy storage in the form of heat or cold. These are a key element in the integration of renewable energy sources such as solar or wind power, which are unpredictable and variable in nature. Storing surplus energy when production exceeds demand allows it to be used when production falls but demand remains high.

Own power plant by means of photovoltaic installation

If you are considering setting up your energy bank, you cannot ignore photovoltaic technology. Photovoltaic systems convert solar energy into electricity. In this way, the sun's energy can charge the batteries in your energy bank, enabling you to cover your domestic electricity needs.

The energy produced does not have to be consumed immediately - you can store it and use it when you need it. With the right choice of the number of panels and the capacity of the energy bank, such an off-grid installation will allow you to be completely independent of the power grid.

Energy bank as a good investment

Investing in an energy bank has many advantages. First and foremost, an energy bank enables you to save money on your electricity bills by storing energy when it is cheapest (e.g. at night) and then using it when it is more expensive. Besides, an energy bank is the assurance that power cuts will not affect the comfort of our lives or the running of our business.

Why choose an Extralink Lightning inverter?

The Extralink Lightning is a high-power inverter that offers a number of key features. It provides stable output voltage, fast switching and intelligent battery management and advanced protection to ensure safe use. Combined with Extralink-branded 24V batteries, it creates a reliable UPS system, making it ideal for building a power bank.

How do you use an energy bank in your home or business? A power bank is an invaluable backup in the event of an emergency. Thanks to its short switching time, the Extralink Lightning provides continuous power, allowing devices to run uninterrupted. It can power critical systems such as servers or security systems, as well as basic home appliances such as fridges and televisions.

Your personal energy storage: installation and capacity Creating an energy bank with the Extralink Lightning inverter means having your own energy storage, the capacity of which you adapt to your needs and capabilities. This can be a simple system consisting of a few batteries, as well as an extensive system capable of powering an entire household or office.

Advantages of using renewable energy sources Using renewable energy sources, such as solar energy, is a response to climate change. An energy bank combined with a photovoltaic installation allows solar energy to charge batteries, reducing dependence on the power grid and allowing the use of surplus energy, contributing to environmental protection.

Optimising consumption: when to store and when to give away energy? The Extralink Lightning inverter with energy management function allows you to intelligently manage the energy produced. Excess energy is stored, and when the batteries are full, you can return the excess to the grid, which can result in additional savings.

Start-up support: grants for photovoltaics Investing in a photovoltaic system can result in significant long-term savings. In addition, subsidies are available in many countries that can significantly reduce initial costs, encouraging investment in renewable energy sources.

Saving with photovoltaics: kWh at the price of pennies The size of your installation and weather conditions will determine how many kWh can be produced in a day. Even a small photovoltaic installation can cover your basic domestic energy needs, which will noticeably reduce your electricity costs.

Energy independence: storing energy for the future Having your own photovoltaic installation allows you to store energy that you can use in the future, for example during peak consumption in the evening, avoiding expensive energy tariffs.

Energy on call: mains failure is not a problem The energy bank ensures that vital equipment is supplied with power in the event of a mains failure, which is invaluable in a situation like this.
