In this video I replace the stock shutter battery charger with a Victron DC-DC charger, extend the charger contact points and add in a modified SOnOff Basic R2 WiFi Relay for remote control of the shutter power supply.
Having the remote power control will benefit when there is a comms lock up and need to power cycle the controller board to recover.
The SOnOff Basic R2 is designed for use with mains AC, so I modified this for running off the DC supply and details of that modification can be found on my website at:
www.daves-astrophotography.co...
The Victron Energy unit is the Orion TR-Smart 24-12 DC DC Charger and has charging capability up to 20 Amps. After setting up the unit I paired it with the Victron Connect app on my phone, and configured it to operate in Charger Mode, with a Smart Lithium battery and disabled the 'engine detect' cut off feature.
This is the 7th part of the series related to the off-grid solar power system I have built for the observatory.
