Solar Generator

This is the design of an off-grid electrical power system. It is intended for a tiny house I’ve build. The design philosophy is that a discharged battery should be charged within a days worth of sunshine, also in late autumn and early spring.

Update

I added a 70cm LoRa transceiver so I can remotely monitor the battery. It uses LoRa APRS and my own APRS telemetry protocol. See https://www.meezenest.nl/mees/aprs_telemetry/
