I live in Bieszczady, I have photovoltaic energy, my own energy storage, I am independent. I was thinking about Ioniqu 5
Mr Andrzej once wrote to us that he launched the first charging point for electric vehicles in Bieszczady. We asked about the fundraising by the Office of Technical Inspection (it happened a few months later), the price (2 PLN / kWh), but we were not able to compile a larger article based on this information. Until the day we found Mr. Andrzej on Twitter. It turned out that it has its own energy storage and is completely independent of external electricity suppliers!

Energy independence on a real example
Www.elektrowoz.pl editorial office: You have opened a charging point in Bieszczady. Planning to switch to an electrician? Have you changed already?
Yes, we have built two parking spaces with a charging station at the Ursa Maior brewery in Bieszczadzka (photo below). In the meantime, this is the place to recharge electric vehicles. We intend to buy an electric car in the near future if it meets the requirements of Bieszczady. As in Bieszczady: it must have good ground clearance and a 4x4 drive.
I saw on Twitter that you have an energy storage device. Is it at home? In company? Why did the Lord decide that the Lord needed him?
This is a piece of agricultural equipment. From the very beginning of creating my place on Earth - away from civilization - I knew that I had to be independent. This is a standalone installation, not connected to a network.
Is this a commercially available product? Or maybe your own invention?
This is an original conglomeration of several solutions. It consists of 2 kW Polish photovoltaic panels mounted on a solar rail [sun tracking module - approx. Ed.]. editor www.elektrowoz.pl]. Provides stable charging of Slovenian stationary TAB batteries. The energy for the warehouse is also generated by an American wind turbine WHI-500 with a capacity of 3 kW (temporarily under repair). All this is complemented by an American charge controller and an Outback inverter.
The farm consists of several buildings, the main one is large, I heat with firewood. But I focus on one room or… I don’t heat at all because I don’t want to mess around with firewood 🙂 Household hot water (DHW) is first and foremost the sun.
What cells / batteries were used to create the energy storage? What is the capacity?
The heart consists of 12 batteries 2 V OPzS 1200 Ah. The 24V voltage feeds the inverter, which supplies 230V output and transfers it to the farm installation. [The total battery capacity is 28,8 kWh, but when assessing the available energy, the losses introduced by the inverter must be taken into account - approx. editor www.elektrowoz.pl]
If suddenly there was no electricity, how many days would you be able to function normally, use a light, a laptop or a telephone?
The farm is completely independent, I rely on my energy, so there is no possibility of a lack of energy. First, the batteries are large enough to provide power at night and in cloudy weather. Secondly, all home installations are as energy efficient as possible.
On average, I use 2 kWh per dayand we usually use refrigerators, freezers, lighting, washing machines, submersible pumps, central heating pumps, computers and of course a coffee maker 😉
Thirdly, relying on the energy produced by himself, a person learns to be economical. He knows when he can afford, for example, welding (because there is also a welder) or sawing wood with an electric saw 😉 And fourthly, in the event of a breakdown, such as a lightning strike, all the necessary elements are retained. in stock. The broken module (inverter, charge controller) is removed, a new one is inserted, and the power returns to normal.
This is an innovative solution, so now the most difficult question is: what were the costs of photovoltaic cells, storage devices and the rest of the electronics?
The installation in its current form was created in 2006 and has been working flawlessly since then. All this costs about PLN 100, although some components are now much cheaper, such as photovoltaic panels.... Much was done on our own, especially since in 2006 there was not much room for such an installation in Bieszczady, and not a single electrician wanted to cooperate.

If you lived in a city, would you choose an energy storage device? Or otherwise: would it be economically viable if, for example, it was charged at a cheap rate at night and used during the day?
Yes, as long as he provides me with backup power. And the economic meaning is changing. If the promise of uninterrupted power supply is fulfilled, the warehouse will cease to be profitable. But with a power outage, a sudden power outage, it becomes worth its weight in gold.
You mentioned that the next car will be the V2G. Have you ever wondered about a model that requires a dedicated solution (like Leaf), or maybe E-GMP vehicles, Ioniqa 5 / Kii EV6?
Basically, a V2G car will be an integral part of the current system. Powered by the sun, the farm will work. We were close to buying an Ioniq 5but in the end it seemed to us rather delicate, given the conditions of Bieszczady.
I'm waiting for something stronger to come along, not necessarily stuffed with entertainment systems because I don't have time to use them, but instead it might fit the realities in this area. Meaning: terrible contact with a lot of snow and mud, frost under the clouds and wind, reliabilitybecause we have several hundred kilometers to the nearest dealer. The actions of the service do not really amuse me in such a situation.
Of course I am looking for a sensible V2G solution too. In this case, the electric car has a chance to become more than four wheels to move from point A to point B. The car becomes a component of the energy system that works and stabilizes the microgrid around the clock.
