What is energy storage used for?
Energy storage can be compared to a powerful battery for the whole house, which stores the electricity produced by photovoltaics when there is too much and gives it back when we need it.
What are the ways of storing energy?
Currently there are five ways of storing electricity:
mechanical (using compressed air storage)
electromechanical (batteries and rechargeable batteries)
chemical (creation of hydrogen or methane)
electrical (super capacitors)
thermal (accumulation of sensible or latent heat)
The most common means of energy storage are electromechanical solutions such as batteries/batteries. 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 10 times the life and twice the depth of discharge (100% - 0%) of popular acid batteries, while being much safer and more durable than popular lithium-ion cells.
With the stability and safety of use that GC PowerNest energy storage offers, the warranty is as much as 10 years or 15,000,000 Wh of worked energy.
How does energy storage work?
Energy storage works on the principle of storing energy when there is too much, and giving it back when needed, which can be likened to the battery in a powerbank or smartphone, but suitably larger and more advanced to be used safely at home.
Battery storage devices usually work with a photovoltaic system through an inverter, which controls the entire process of extracting energy from the photovoltaic, storing it, and giving it back.
GC PowerNest is a single-phase, 48V energy storage with a 5 kWh capacity and an efficiency of over 98%, which means that for every 100 units of energy supplied to the battery, you will be able to reuse 98 units. With such high efficiency, you are assured that storing energy is much more beneficial than feeding energy directly back into the grid, which often involves a loss of more than 20% against the energy generated or unattractive rates for selling energy at times of high energy production throughout the day.
What opportunities do energy storage offer?
Energy storage is essentially the possibility of storing surplus energy produced without having to sell it back at an unfavourable price. This is not only economically viable and profitable, but also good for the environment, as we store energy from photovoltaic panels in an environmentally friendly way so that we can use it locally when needed.
Does energy storage pay off?
Definitely yes! A photovoltaic installation combined with an energy storage facility enables a quicker return on investment and makes it possible to become largely independent of changes in the price of electricity, resulting in lower and stable monthly electricity bills.
The key is to select the power of the installation so as to maximise self-consumption of energy (using the electricity produced at the place of generation) without generating significant surpluses. Energy storage acts as an energy buffer in such an installation, carrying energy from peak production (around midday) and allowing it to be used later when the sun is setting or when it has completely set.
How long can I power my devices with energy storage?
Everything depends on the electricity demand of the equipment and the capacity of the energy storage itself.
The average electricity consumption in Poland per three-person household is 5.47 kWh, so it can be assumed that a battery acting as a supplement to a photovoltaic installation, with a capacity of 4.5 to 6 kWh, is the optimal proposition for most users.
Is the device safe?
The GC PowerNest has the required certifications necessary for its use, and goes above and beyond with self-diagnostic systems that monitor the ongoing health of the unit. With additional in-house testing by Green Cell's R&D department, we know that the unit is ready for long-term, uninterrupted operation throughout its lifetime.
Do I have to have a photovoltaic installation to use energy storage?
Although a photovoltaic installation is often an indispensable part of an energy bank, it is not necessary for its use. Such an energy bank, with the use of an appropriate inverter, can be used as a battery that will store energy allowing your home or small business to operate uninterruptedly during power cuts.
Is energy storage suitable for my photovoltaic installation?
The GC PowerNest is a single-phase energy storage unit with a capacity of 5 kW and 5 kWh. Currently, photovoltaic installations below 3.68 kW are single phase (unless otherwise requested by the customer). This means that on a sunny day you can charge the battery in less than 2 hours.
Can I connect my inverter to energy storage?
GC PowerNest has an extensive list of compatible inverters (inverters) with which the device communicates. You can view the list of compatible devices here::
https://greencell.global/img/cms/ESGC01/GreenCell%20PowerNest%20_%20ESGC01%20-%20compatibility%20list%20-%20ESGC01.pdf
We are constantly making efforts to develop GC PowerNest compatibility with more devices, so even if you don't find your current inverter, it doesn't mean that such functionality won't appear in the future.
Do I need a special room for the energy storage?
Absolutely not! The GC PowerNest energy storage can be used in your home wherever you desire. Its all-metal casing, with a universal design, can become an interesting design element of your home or office. The only condition is that it is installed according to the instructions in the user manual and that the cables are properly routed by an authorised person.

Definitely yes! Producing and consuming electricity from renewable sources at the point of generation is the most environmentally beneficial model of electricity use due to minimal power losses.
The GC PowerNest energy bank is a device that has a warranty period of as much as 10 years and a useful life that goes far beyond that, so the environmental benefits extend beyond the burden of just producing the energy bank.

The combination of these two features can make your home appear as a green spot on the map, thus contributing to a more sustainable development.
What is the lifetime of an energy store?
GC PowerNest energy storage comes with a long, 10-year warranty (including the batteries, which should still have more than 60% of their capacity after running 15,000,000 Wh)
Energy storage for a single-family house
The use of energy storage combined with a photovoltaic installation in a single-family house brings a number of immediate benefits. as well as those that will appear in the near future due to the rapidly rising electricity prices.

SAVINGS - significant reduction in electricity bills (in some cases even to 0) thanks to an efficient model of energy generation and use.
ENERGY CONTINUITY - insensitivity to network congestion, possibility of feeding energy into the network outside peak hours according to one's own demand.
SAFETY - the battery is made of durable and safe LiFePO4 cells with systems continuously monitoring the operation of the device, which ensures uninterrupted operation of your photovoltaic installation.
TECHNOLOGY - PowerNest has an efficiency of over 98%, so you will use almost all the electricity produced from the solar panels at a later time, allowing a shorter payback period.
ECOLOGY - the island consumption of green energy from a photovoltaic installation is the best way to reduce your carbon footprint, thus contributing to a more sustainable development of your household.
COMFORT - thanks to the use of a suitable inverter or external device, it is possible to protect your home from power cuts so that you can enjoy your life uninterrupted - no matter if you are devoting yourself to music, reading a book or having fun with friends.
EXTENSIBILITY - you can complete your investment with a single PowerNest energy storage unit, and when you decide you need a larger power bank, just get another battery. This way you can connect up to 8 devices reaching as much as 40 kWh capacity.
Energy storage for companies
The use of energy storage combined with photovoltaics gives you the opportunity to protect your business against unexpected events that may affect profitability (such as power outages, for example), so that regardless of your business profile you will be able to maintain continuity of production or service provision.
The combination of solar panels and battery also contributes to a real improvement in your company's condition, thanks to the reduction of fixed costs by aiming at a state of zero-export of the produced energy, which results in a real reduction in the monthly costs incurred for electricity, and the funds thus saved you will be able to reinvest in new visionary projects.

In addition to the material benefits of a photovoltaic installation combined with energy storage, it is worth noting that companies that choose to invest in renewable energy sources are seen as more modern and responsible in the eyes of customers, who are increasingly paying attention to these aspects in their purchasing decisions.
Energy storage for the farmer
By maintaining the energy independence that comes from combining energy storage with a photovoltaic installation, farmers are able to ensure the safety of their livestock or appropriate crop storage conditions. This is worth thinking about, especially as farms are usually located further away from key infrastructure and, in the event of emergencies, the damage caused can take from several hours to several days to repair. In addition, a modern, eco-friendly farm aiming to reduce its carbon footprint is a forward-thinking trend that consumers are increasingly keen to embrace.
