Construction of large and small scale solar farms - generate the energy from the sun, charging to LiFePO4 batteries and then using the energy from batteries in off-grid or hybrid mode - independent source of energy.
K+K, spol. s r.o. is many years interested in renewable energy business, especially its company CEO. Our main activity is generation of electric energy from renewable energy sources, especially using the solar energy - photovoltaics.
We have a certification “Construction of renewable energy resources” in sections: - photovoltaics
In accordance with the Directive of the European Parliament and the Council no. 2009/28/EC under Article. IV on the promotion of energy from renewable resources.
Our main partners in development, production and construction renewable energy resources are companies FitCraft Production, FitCraft Energy and in case of solar farm construction we cooperate with companies ETV Zlín, Dagger Construction, MK Chýnov, ALOKO.
During the years 2008 and 2014 we successfully finished 35 large solar farms, with installed power capacity of 83,91 MWp in Czech Republic, Slovak Republic, Ukraine, Italy and in UK.
We also successfully finished many small scale solar installations on industry buildings and houses.
At this time we are also engaged in off-grid and hybrid systems, which are very useful in places where is no grid connection.
FitCraft Energy developed, tested and putted on market revolutionary LiFePO4 battery with active BMS. Battery weight is only 16kg, has nominal voltage 48V and capacity 1,5kWh / (50V/30Ah). LiFePO4 battery cells can hold their capacity for more than 4000cycles of charge to 100% and discharge to 0%.
Active battery management system “BMS” is electronic device, which takes care of each battery cell during the process of charging and discharging. With BMS you will enlarge the life span of LiFePO4 battery cells and also the life span of the whole battery pack.
These batteries are equiped with voltage, current and temperature protection. You can remotely check each battery on-line (nominal voltage, current, temperature, capacity … etc).
LiFePO4 battery pack is ideal mobile depository of electric energy you produced with your solar system, wind power plant or diesel generator … etc.
You can take the energy from batteries by using DC/AC inverter (230V/50Hz) and supply your devices, your home, with electric power.
In case you will use 3 hybrid systems you can supply 400/230V, 50Hz.
Start to be self sufficient by using your own off-grid or hybrid system and become independent from your DNO.
