What is the energy storage for?
Energy storage is like a giant whole-house battery that stores the electricity produced by photovoltaics when there is too much of it and releases it when we need it.
What energy storage options are there?
There are currently five ways to store electricity:
mechanical (with compressed air reservoir)
electromechanical (batteries and rechargeable batteries)
chemical (production of hydrogen or methane)
thermal (accumulation of sensible or latent heat)
The most famous form of energy storage are electromechanical solutions such as batteries/accumulators. GC PowerNest is just such a solution. At the heart of the device are LiFePO4 (Lithium Iron Phosphate or LFP) cells, which have more than ten times the life and twice the depth of discharge (100% - 0%) of traditional acid batteries while being much safer and more durable than standard lithium-ion cells.
Thanks to the stability and safety of use of the GC PowerNest energy storage, the guarantee is up to 10 years or 15,000,000 Wh of energy worked.
How does energy storage work?
Energy storage works on the principle of storing energy when there is too much of it and releasing it when needed. This is similar to the battery in a power bank or smartphone, only larger and more complex to make it safe to use at home.
Battery storage usually works together with a photovoltaic system via an inverter, which controls the entire process of energy extraction from the photovoltaic system, storage and return.
GC PowerNest is a single-phase, 48-volt energy storage device with a capacity of 5 kWh and an efficiency of over 98%. This means that for every 100 units of energy that goes into the battery, you can reuse 98 units. With such a high level of efficiency, you can be sure that storing energy is much more advantageous than feeding energy directly into the grid, which often involves a loss of more than 20% in relation to the energy produced or unattractive tariffs for the sale of energy at peak times of daily production.
What opportunities does energy storage offer?
Energy storage is essentially the ability to store excess energy generated without having to resell it at an unfavorable price. This not only makes economic sense and is profitable, but also good for the environment, as we store the energy from the photovoltaic panels in an environmentally friendly way so that we can use it on site when needed.
