The Victron Orion-TR Smart 12/12-30 is an isolated DC-DC charger that takes 12V input and delivers up to 30A at a regulated 12V output. It suits dual-battery setups in vans, boats and trucks, charging a house or auxiliary battery from the starter battery or a smart alternator. Its galvanic isolation separates input and output grounds, which reduces noise and ground-loop problems. Against simpler voltage-sensing relays it charges properly rather than just linking batteries, and its Bluetooth app lets you set charge profiles and monitor the unit.
