I have a SmartSolar MPPT, Orion Dc-Dc (Alternator) and a Pheonix mains charger, which doesnt seem to be an uncommon setup so I'm hoping someone can help!
I really am wanting the kit set up to charge/draw from the sources in that order of priority I've listed them above. So solar first whatever, therefore even if the mains is plugged in and available, if there is sufficient current available from the MPPT then to use that and I essence 'turn off' the mains supply.
Similarly if the Orion is powered up then this should ramp up in favour of the mains if there is no solar available.
This is for charging and light use on a mobile system.
I've been hunting around this forum a bit but struggling to find an answer.
