Notes from hacking today:
Done. System is able to power a 10.8W load consisting of a UniFi UAP-AC-PRO and its POE injector over a 150W AC inverter. We'll plan next steps with T17: Develop calculator for capacity of solar system for capacity planning and T15: Prototype monitoring system to data log real loads.
