The REDARC Manager30 must be mounted in the canopy, trailer, or vehicle rear (not under the bonnet). It manages AC, DC, and solar inputs, with correct cabling, fuses, and all negatives running through the battery sensor for accurate monitoring.
Setup is done via the remote monitor to program battery details and inputs.
On first startup, it completes a learning cycle to establish full battery capacity. Professional installation is recommended.
REDARC recommends seeking the support of a qualified auto electrician or technician.

This information is applicable to the following products:
- Manager30 Battery Management System (BMS1230S3, BMS1230S3-xx)
Tools & parts required
Cable cutters, wire strippers, flat-blade screwdriver
6 B&S (minimum) or 0/2 gauge cable
Cable lugs
60A MIDI fuses with holders
Screws, bolts, zip ties, and heat shrink
Anderson plugs (optional for external inputs)
Mounting location
Always mount the Manager30 in the canopy, trailer, or at the rear of the vehicle.
Never mount under the bonnet.
Main charging unit
The Manager30 manages charging from three inputs:
AC Mains – plug-in power from home or campsites.
DC Vehicle Input – 12V/24V from the vehicle battery/alternator.
Solar Input – unregulated solar panels up to 32V open circuit.
Key connectors:
Green 6-way connector – vehicle, solar, auxiliary battery connections.
CAN connections – link to remote monitor and battery sensor.
Wiring the green connector
Terminal 1 – Auxiliary Battery Positive
Connect to the secondary battery via a 60A MIDI fuse.
Terminal 2 – Load Disconnect
Controls a relay/solenoid to automatically disconnect loads when battery voltage or state of charge is too low.
Terminal 3 – Ground
Connect to the GND side of the battery sensor.
Critical: all load and charger negatives must pass through the battery sensor for accurate current monitoring.
Terminal 4 – Ignition Input
Required for vehicles with smart/variable voltage alternators.
Connect ignition-switched positive if needed.
Configure “DC Input Trigger” in the Manager30 display menu.
Terminal 5 – Solar Input Positive
Connect solar panels (unregulated, ≤32V open circuit).
Terminal 6 – Vehicle Input Positive
Connect via 50A MIDI fuse from vehicle battery using minimum 6 B&S cable.
Wiring the battery sensor
Monitors battery voltage, current, and temperature.
Connections:
BNEG terminal → Auxiliary battery negative.
GND terminal → All system grounds and loads.
Voltage sense lead → Auxiliary battery positive.
RJ45 cable → Charger CAN port.
Wiring the remote monitor
Two display options, both connect via RJ45.
The remote monitor can be mounted up to 2.5m away using the supplied cable. Use the provided template for neat installation.
System setup
Once wired, configure the Manager30 through the remote monitor:
Set time and date.
Enter vehicle input type.
Program auxiliary battery details.
Set alarms and automatic load disconnect options.
First charge cycle
On first startup, the Manager30 calculates what “fully charged” means for the battery.
During this period:
Display may show “Calculating” or remain blank until 100% is confirmed.
Once complete, the system will accurately track state of charge from then on.
