With 18awg, 5A might be possible. You can always wire it up and see what you get.
I'm following this thread because I have similar questions about my own setup.Here is the 100W version.
SD-100A-12 MEAN WELL Isolated DC/DC Converters 102W 9.5-18Vin 12Vout 8.5A datasheet, inventory & pricing.www.mouser.com
Spec sheet here.
Here's the manual: https://www.victronenergy.com/upload/documents/Manual-Orion-Tr-Smart-Charger-Isolated-EN-NL-FR-DE-ES-SE-IT.pdfLooking at a voltage drop calculator I see 40amps going through a 50' run(+/- total circuit) of wire I could go with a little 12 gauge wire and it would still be over 10 volts to the charger. There must be some downside to using that small of a wire? What would be a more appropriate gauge of wire? How big of a wire can that charger physically accommodate? It's hard to tell from the pictures but it looks like 10 or maybe 8.
That's how I figure an all-Victron system will work, but if not, I'll manually shut off alternator or solar charging, as needed.Victron Products are starting to talk to eachother and share info via BT networking, my solar already gets battery voltage from the battery monitor and next firmware will allow multiple chargers to synchronize charge stages via bluetooth, I have to imagine the new DC charger they announced will also join in on this capability sooner or later if not right out of the box.
