What is an energy storage and how does it work?

Energy storage for industry, modular structure up to 20 MWh with a module capacity of 138 kWh.

Possibility of leasing or long-term rental.

Do you have your own RES installation (photovoltaics, windmills, MEW hydroelectric power plant) that gives away most of the energy to the grid? Don't waste your money and choose your energy storage.

If you want to use more of the produced energy for your own needs, you can use an energy storage in your installation. Surplus energy will be stored, and then you will use it in the afternoon and night. The energy storage from NRG can be simultaneously recharged from the grid at a specific time, you can charge the storage during the off-peak hours during the winter months, when the energy is cheaper.

Energy storage - it is a high-quality battery in lithium technology (LiFePO4 - LFP), the energy storage allows you to store electricity from photovoltaics, a windmill or a small hydropower plant. Energy storage in LiFePO4 technology is designed together with a BMS (supervisory system), the BMS system controls the maximum charging and discharging currents, controls the module temperature and voltage. Good-quality energy storage ensures up to 20 years of safe work with photovoltaics.

Energy storage for home and industry. Dedicated container energy storage cooperating with RES.

Smart electricity storage system it's more than a battery. It is a solution that enables loading and unloading the warehouse in modes adapted to the needs of users. What is different energy storage from generators, the use of stored electricity without noise, fuel and maintenance. Our latest product is an energy storage set with an inverter. We have built the set in order to be able to collect and use electricity in a manner independent of the energy supplier.

system EMS

Management system The EMS NRG Project allows you to reduce the costs of purchasing energy in energy-intensive companies.

Independence from the energy supplier - Energy storage enables island operation

Provide the ability to choose a power source in the event of a power failure, even for several hours. The standard NRG Storage module is 138 kWh, you can combine modules and adjust the storage capacity to your needs.

Safety of use - Energy storage in LiFePO4 (LFP) technology

Solutions are built on the basis of LiFePO4 technology. It ensures long battery life (over 6000 cycles) and the highest level of safety during operation.

Save more! Charge the energy storage from surpluses from photovoltaics

You reduce losses resulting from unfavorable prosumers' settlements. You decide how best to use the stored energy. You limit the costs resulting from the power fee. Reduce the cost of purchasing energy for the enterprise, use renewable energy in the evening and at night.

Ecological neutrality for your company

By supplementing the photovoltaic installation with an energy storage, you will maximize the use of the electricity you produce.

The first Polish producer of energy storage systems with inverter

The product was developed by NRG Project sp. Z oo in cooperation with a group of Polish engineers. The set of inverter with energy storage is manufactured in Poland. We offer Polish single-phase inverters for the home, and three-phase inverters with inverter powers of 3 kW, 10 kW, 100 kW, 250 kW, 500 kW.

Function 0 export
