The Manager Alpha50 is a 12V battery management system that charges an auxiliary bank from a vehicle alternator, 240V AC mains and solar in one unit. Puts out up to 50A continuous to run a fridge, lights, inverter and 12V accessories off the house battery while the start battery stays recovered and ready. Fits caravans, camper trailers, motorhomes, 4WD tourers and van conversions that need one piece of gear covering every charge source.
The chassis is 400 by 154 by 120mm and weighs 5.8kg, with a 9-32V DC start-battery input, a 9-32V DC solar input and a 95-264V AC 45-65Hz mains input built in. RedVision Pro display and a Smart Battery Monitor ship in the box, with Bluetooth 5.1 pairing out to 42 metres through the Redarc app. Green Power Priority pulls from solar first, then the alternator, then mains, so the free electrons go in first.
The Alpha50 is a non-sealed unit with a 240V AC input, so it mounts inside the vehicle, not in the engine bay. Fuse the start battery, solar and house battery sides to protect each path, and have the 240V AC side wired by a licensed electrician. We do both in our Perth workshop under EC17073.
What sets it apart
Three inputs, one unit — alternator, 240V AC mains and solar built in.
50A continuous output — real headroom for a fridge, lights and a small inverter.
Green Power Priority — solar first, alternator next, mains last, so free electrons go in first.
Start battery recovery — keeps the crank battery charged and brings a flat one back.
RedVision Pro display — real-time state of charge, current flow and run-time estimates.
Bluetooth 5.1 to 42 metres — monitor and set profiles from the Redarc app on the phone.
Mounting and install
The Alpha50 is 400 by 154 by 120mm and bolts to a solid flat surface inside the vehicle. The chassis is not sealed and the 240V AC input is regulated electrical, so engine-bay mounting is unsuitable and the mains side must be wired by a licensed electrician. We install it in our Perth workshop under EC17073 and run the start-battery, solar and house-battery cables to size with the fuses that protect each path.
If the install is DIY, read the Redarc Manager Alpha50 manual before pulling anything apart. The 240V AC lead off the Alpha50 must terminate in a compliant appliance inlet and lead that satisfies AS/NZS 3000; use a licensed sparky for the mains side.
