Using an example consultation, we illustrate the key aspects of analysis and recommendation – from investment costs and safety requirements to long-term savings potential.
Customer:
I'm planning a photovoltaic system with battery storage for my company. I am considering whether I should invest in a 160 kWh storage system to maximise my self-supply or whether a 100 kWh storage system would make more sense due to the simplified framework conditions. What are the differences and what is the best solution for my needs?
Expert:
These are very legitimate questions. I'll be happy to explain the pros and cons of both systems.
Customer:
What specific advantages does a larger storage unit offer me?
Expert:
A 160 kWh storage system offers you the following advantages in particular:
Customer:
What technical and structural requirements do I need to consider?
Expert:
Even smaller storage systems up to 15 kWh are already considered systems with an increased fire risk and should be installed away from escape routes and flammable materials.
In addition, the installation of battery storage systems must comply with the safety requirements of the Low Voltage Installation Ordinance (NIV). Other relevant standards include NIN 2020 (SN 411000:2020) and the VKF fire protection leaflet for lithium-ion batteries.
Customer:
How does the choice of storage size affect my costs?
Expert:
The return on investment of a storage system is basically the difference between the savings from self-supply, the revenue from feeding into the grid, and possible income from the provision of system services.
Customer:
What memory size do you recommend?
Expert:
That depends on several factors:
Ultimately, you should carefully analyse your consumption data, site conditions and growth plans in order to find the optimum compromise between investment and operating costs.
