1.2 These GTC apply only to those Contracts that expressly refer to these GTC. The content of the Contract is always determined on the basis of a quotation prepared by the Contractor and accepted by the Client.

Article II.
Execution of the Work

2.1 Unless otherwise agreed by the Parties, the Work shall be completed when the Equipment is installed by the Contractor at its destination. Unless otherwise agreed by the Parties, transportation to the destination shall be arranged by the Contractor.

2.2 The date of taxable performance is the date of acceptance of the Equipment by the Customer and the signing of the acceptance report of the Equipment at the agreed destination.

2.3 The risk of damage to the Equipment shall pass to the Customer:
a) if the Contractor is transporting the Equipment to the Customer, on the date on which the means of transport with the Equipment arrives at the agreed destination and
b) if the Customer is transporting the Equipment to itself, on the date on which the Equipment is ready for loading onto the Customer’s means of transport at the Contractor’s premises.

2.4 The Equipment is a unique device manufactured to the Customer’s exact requirements and to meet the Customer’s specific needs. It is for this reason that a pre-test may be carried out by the Contractor prior to its completion. There the Client has the opportunity to continuously check the performance of the Work and to suggest possible modifications to the Equipment. If the Parties agree on a pre-commissioning of the Equipment, this shall always take place at the Contractor’s premises.

4.2 In the event of the Contractor’s withdrawal from the Contract, the Client is obliged to pay the Contractor a contractual penalty of 100% of the price of the Work (meaning the price excluding value added tax). With the Contractor’s consent, other arrangements may be made if the Contractor has not spent all the costs contemplated in the Contract for the execution of the Work, i.e. in particular if the Client withdraws from the Contract before the Work has been executed. For the avoidance of doubt, the Parties state that they each consider the contractual penalty in the above amount to be fair and in accordance with good morals and the principle of fair commercial dealing. By way of explanation, the Parties state that the Equipment is a unique piece of equipment manufactured precisely to the Customer’s requirements and to meet its specific needs. Therefore, no resale of the Equipment to a third party or any other use of the Equipment is possible. However, in the event of the Contractor’s withdrawal from the Contract, the Customer may, upon payment of the contractual penalty, demand the delivery of the part of the Equipment manufactured up to the withdrawal; the costs associated with this shall be borne by the Customer.

4.3 Time limits for the performance of the Work and other time limits which the Contractor is obliged to observe in the performance of the Work shall not expire during the period of delay of the Client in providing the assistance which the Client is obliged to provide to the Contractor.

Article V.
Liability for defects

5.1 The Contractor shall be liable for defects in the Equipment at the time of its performance of the Work and for defects occurring in the Equipment during the warranty period (if agreed). The warranty period for the Equipment shall be 12 months unless otherwise stated in the quotation.
5.2 The Customer shall notify the Contractor of defects in writing, specifying the exact extent and nature of the defect. The Customer’s claims arising from defects shall be extinguished if he fails to notify the defect in the prescribed manner within ten days of the date on which he could have become aware of it with the exercise of professional diligence. If the defect is reported in writing within the warranty period during working hours from 7:00 a.m. to 5:00 p.m., we guarantee that we will start processing the claim within 24 hours of the next working day.

5.3 The Contractor shall determine the manner and time limit for the satisfaction of defect claims in a manner that is consistent with the principle of fair dealing, taking into account the nature of the defect.

Frequently Asked Questions

Here you will find answers to frequently asked questions about our products, their functionality and service requirements.

  • What is a battery energy storage system (BESS) and what is it for?

    BESS (Battery Energy Storage System) is a technology designed to store electricity in batteries, allowing flexible and efficient use of energy according to current needs. Such systems help to stabilise the power grid, reduce dependence on volatile electricity prices and increase energy independence by enabling the efficient use of energy from renewable sources such as solar or wind power.

  • What are the main benefits of BESS for industry and commercial entities?

    The main advantages include:

    – Cost optimization – Stored energy can be used at peak times when electricity prices are high, reducing operating costs.

    – Backup power source – BESS provides reliable backup during power grid outages, ensuring continuity of production and operations.

    – Grid Load Balancing – The battery system can balance the imbalance between generation and consumption, preventing grid congestion and stabilizing supply.

    – Renewable Energy Support – Stores excess renewable energy and allows it to be used when resources are not available (e.g. at night).

  • How long will the battery energy storage system last?

    The lifetime of a battery system depends on several factors such as the quality of the batteries used, the intensity of use and the method of maintenance. Standard lithium-ion batteries typically have a lifespan of 10 to 15 years when operated properly. Thanks to advanced energy management technologies, lifetimes can reach even higher values without significant capacity loss.

  • How is the BESS connected and what are the requirements for its installation?

    BESS can be connected to the grid either directly as part of the building energy management or as a stand-alone system with islanding capability. Installation requires space for the location of the battery modules, the right climatic conditions as well as expert installation and connection. An important aspect is also the sizing of the system according to the needs of the building and the typical consumption.

  • What are the safety precautions when using BESS?

    Modern BESS are equipped with advanced safety mechanisms including:

    – Thermal Management – Ensures that the batteries operate within the optimum temperature range.

    – Overload and short circuit protection – Prevents system damage and reduces the risk of fire.

    – Early Warning System – Monitors the status of individual battery cells and alerts you to any irregularities, reducing the risk of failure.

  • Can BESS be expanded if my energy needs increase?

    Yes, most modern battery systems are modular and scalable. This means that additional battery modules can be added as needed to increase the capacity and performance of the entire system. However, this expansion requires expert consultation and adaptation of the system to the new conditions to ensure optimal integration.
