Quasi-balcony PV system of 5 modules on a facade wall of a highrise building with Solarfabrik S5 modules, mounting system by Mo Energy and Marstek AC connected Battery of 5 kWh. The installation had more than one year of planning phase as installing at this height is definitely not standard, and the installation size and type were uncertain. I was really happy about the help of a industrial climber, and more than happy about the outcome. Thank you! I could not have done the installation without help.
