FUSE BOX
Charge your batteries with your alternator or with the sun. The charger comes with an inbuilt 25/40A
MPPT solar regulator which has been pre-wired to a dedicated solar Anderson input on the side of the
box. Compatible with LiFePO4, AGM, SLA, Gel, and Calcium batteries, it’s the perfect addition to any
12V touring setup.
Get up-to-date information on your battery in an instant. The inbuilt battery monitor has a measure of
your battery’s voltage, current draw, and state of charge as well as a temperature gauge and two timers
that track your battery’s remaining charge and discharge time.
Take control of your 12V accessories. Designed to give you a quick DIY install for your hardwired
accessories, the switches are ideal for control of items such as lights, pumps, and fridges. Each switch is
backlit, and the kit comes with an array of adhesive emblems to make identifying your switches easy.
The side of the box has two DC-DC ports – one as a dedicated solar input, the other, as a three-pin
Anderson-style plug used to hook into your alternator and ignition source.
Constructed using heavy-duty grey powder-coated aluminium, our 12V Control Hub is perfect for
mounting in the back of the canopy, in DIY camper trailer or van builds. The box is easy to mount:
simply use the pre-drilled holes on the back of the unit to screw, rivet, or bolt it into place, to give you
convenient access to just about everything you need in your 12V setup. The system comes completely
fused and pre-wired, meaning all you’ve got to do is hook up your accessories.
Easy to access fuses. Made to protect the panel’s outputs, the fuse block contains six fuse ports, with an
additional two to hold your spares. There’s also an LED indicator that lights up when a fuse has blown.

6MOUNTING
CONTROL HUB INSTALLATION
Ideally suited to being mounted up on a 4x4 canopy wall, or in a camper trailer, the control hub is best
located in an area that’s easy to access and offers protection from dust and water ingress.
The unit should be mounted with consideration as to where/how you will be running your wires into/out
of the box. Make sure the box has adequate space around it to make wiring easy.
1. Using a Phillips head screwdriver, remove the
four screws found on each corner of the front
face of the unit.
2. Next, mark the mounting points on your wall/
surface. To do this, hold the box up to the
surface, and use a pen to mark the surface
through the box’s pre-drilled mounting holes.
PREPARATION
PROCESS
3. Then, put the control hub down and drill through each marking on your surface. To match the box’s
holes, you’ll need to create a 5mm hole. Note: If mounting to a metal surface, you may need to drill
a smaller pilot hole before drilling it out.
4. The box can now be lifted into place and secured to the wall. Thread an M5 bolt through each hole
and through the mounting surface, then fasten with suitable washers and nuts.

9INSTALLATION
CONTROL HUB WIRING  ACCESSORIES
• Disconnect the unit from power prior to wiring the switches.
• To wire into the switches, make sure your appliances are fitted with leads that are a minimum of
14AWG cable. Larger appliances may require cables at up to 10AWG.
• Each negative lead will require a 6mm ring terminal, whilst the positive requires a 6.3mm female
spade connector.
For wiring up any accessories that don't require a switch, simply wire the positive lead to the positive
busbar rather than the switch. The positive lead will need a 6mm ring terminal
WIRING ACCESSORIES WITHOUT A SWITCH
WIRING ACCESSORIES TO A SWITCH
1. Remove the front face of the unit by unscrewing the four screws found on each corner.
2. Locate a practical route for the wires to enter the hub from the appliance. Choose from one of
the four grommets on the unit, cut a cross through the centre of them, then run the cords from the
appliance into it so that there is about 30cm worth of lead in the box.
3. The positive lead can then be connected to the back of the switch. If your wiring is dual-core, you
may need to separate the two wires to do this, otherwise, place the female spade connector from
the positive lead onto the vacant male spade on your chosen switch.
4. Next, connect the negative eye terminal to one of the bolts on the negative busbar. Then repeat the
process for your other appliances, tucking the cables into the box once complete.

10INSTALLATION
CONTROL HUB WIRING  INVERTER
• Consult your inverter’s user guide prior to installing through the hub.
• Take into consideration the appropriate cable gauge and fuse size needed to run your inverter. You
will need to use heavier gauge cables running from both the battery into the hub and from the hub
to the inverter.
• Some cables used will be too large to fit into the existing rubber grommets. You may need to modify
the box, drilling in larger holes to fit them.
• The positive and negative cables used to connect to the box should have 8mm eye terminals.
PROCESS
1. Remove the front face of the unit by unscrewing the four screws found on each corner.
2. Locate a practical route for the wires to enter the hub from the appliance. Run your leads from the
inverter into the box through one of the four grommets, or drill another hole if necessary.
3. There should be a vacant large bolt on the positive busbar. Secure the positive lead to this bolt.
4. Repeat the process above for the negative lead to the negative busbar.

11 INSTALLATION
• Ensure that only a dedicated 12V battery/battery bank is used with the system.
• Make sure that the battery is of either SLA, AGM, Gel, Cal, or LiFePO4 chemistry.
• Inspect the unit internally to make sure that all the leads are in good working order and are of an
appropriate gauge.
• The kit does not come with any additional leads to wire the battery. Make sure to use leads that are
free from faults or frays and are of a suitable size being at least 6AWG. The leads used to connect
to the hub should have an 8mm eye terminal for the positive, and a 10mm eye terminal for the
negative as it will be attached to the shunt.
PROCESS
1. Remove the front face of the unit by unscrewing the four screws; one on each corner.
2. Locate the most practical route for the wires to run from the battery into the control hub. There are
grommets on all four sides giving you multiple options. Once located, cut a cross into the centre of
the rubber grommet using a knife.
3. Run your battery leads through the cut grommet so that there is about 30cm worth of lead in
the box. We recommend using a minimum of 6AWG cable, however, if the battery is located a
considerable distance from the box, you will need to use a larger gauge wire.
4. In the box, connect the terminal end from the positive lead to the main bolt on the positive busbar.
5. Next, connect the terminal end from the negative lead to the negative bolt on the shunt.
6. To complete this process, connect the cables to the battery. Connect the other end of the positive
cable first to the battery’s positive terminal, then connect the negative end to the battery’s negative
terminal.
