3 main parts for doing. goal finishing end of summer (30.09).
1. Testing of components (MPPT, BMS)
2. Installation of Energy System in Fablab St.Pauli
3. Monitoring
next steps:
basic concept
concept for discussion @CollectiveOpenSourceHardware/00_reproduction_prototyping
Testing the BMS:
Messplan:
@Tatytorres @SchneiderAn - Hey guys, whats the status with testing the components?
Brainstorming
place to put solarpanel depending on irriadtation (-> pyranometer)
installation of solarpanels, mountin & wiring (-> how much wire we need?)
connecting to box
[ ] wires, mounting hardware
[ ] testing devices -> pyranometer, multimeter
calculation efficiency of whole system (solarpanels, MPPT, BMS, battery)
maximum output, behaviour (temperature, efficiency level, nominal point)
traces for validation (system parameter)
choosing differents loads
standards for decentral energy systems? VDMA, VDE?
[ ] sheet with testing procedures
[ ] preparing folder in github
