Background
Solar Power: From a marginal ecological contribution to the backbone of a renewable power supply system
100 kWp Solar PV • Hourly average power• Resolution like it is
used in simulation like Homer
• From 10 AM to 5 PM is minimal output > 30 kW
Data interval 1 Hour
Data interval 1 Minute

Engineering
Selection / development of main components
Battery system (Samsung):
bankable warranty offer with Samsungserviceable (single modules can be replaced by 2 persons on-site)expandable due to modularity of inverter design
Battery Inverter (Maschinenfabrik Reinhausen):
modularity – in steps of 5 x 30 KW - and 4 x 100 KWeach inverter module is able to control it´s sample of battery modules independently • easy replacement and maintenance,• scalable and flexible design opportunities
spare part availability of min. 10 years
