20201228 rC3 Meetup

EventGrid // DC MicroGrid Meetup Day 2

• Severin //tiefpunkt: https://wiki.munichmakerlab.de/wiki/DC_Microgrid
• Chewie: playing around with some gear that accumulated. Panels on the house, some EP.. controller. Looking at LibreSolar controllers

Charge Controller - https://www.western.it/en/products/wrm15-dual-battery/ - looks good, but android app is useless, and their support is not helpful in fixing the problem. comments in the Italian play store also say it doesn't work, and has a poor rating.

• bitsandbytes: interested in how camp solves power
• mc_leeck: interested mostly in motors, but looking at the power side of things as well
• cfr34k: interested in ren. energy, esp. solar power. had built an mppt charger (12V,50W).
  • not really documented, but would build it similar to the LibreSolar MPPT 12V 10A device (see below)
• HeNeArXn: just checking in what has happened
