I don't see the 12 V to 12 V DC-DC 30A charger on the web pages any more. Oversight, or is the product discontinued?
It's still showing up on the product sheet, but you won't know from the web page that 12|12 V is an option. https://www.victronenergy.com/upload/documents/Datasheet-Orion-Tr-Smart-DC-DC-chargers-non-isolated-360-400W-EN.pdf
If discontinued, what is recommended device for this application...one of the solar charge controllers??
