Overview
The REDARC Manager Alpha50 with RedVision is a complete, all-in-one 12V battery management system engineered to deliver up to 50A of charge from three simultaneous power sources — your vehicle's alternator (DC), mains or shore power (AC), and solar panels. Built in Australia and tested to the world's toughest vibration standards, this compact unit is up to 55% smaller and 28% lighter than competing multi-device setups, making it one of the most capable and space-efficient power solutions available for caravans, camper trailers, and motorhomes. The integrated Green Power Priority™ technology intelligently prioritises solar input to reduce alternator load and save fuel, while Start Battery Charge and Recovery modes ensure you're never left stranded with a flat start battery.
Designed for serious Australian adventurers — from those touring the red dirt tracks of the outback to caravanners doing lap-of-Australia trips — the Manager Alpha50 is purpose-built to keep your auxiliary batteries charged and your accessories running no matter the conditions. Whether you're dry-camping off-grid in the bush, parked at a powered site in a caravan park, or driving between destinations, the Manager Alpha50 seamlessly switches between power sources to keep your fridge, air conditioner, lighting, and induction cooktop running. Paired with the RedVision display and Bluetooth app, you get real-time state-of-charge, current flow, and remaining charge data at your fingertips — giving you total confidence in your power system on every trip across Australia.
