The EGON DC-Hub Dual is even more the king of simplified, standardised and effective builds for your 4WD, mining vehicle, caravan or tiny house projects. By incorporating the capability to connect x2 DC/DC chargers rather than x1 with the DC-Hub, you can build a 100Amp DC/DC charger and solar system for a fraction of the cost that systems cost that will provide 100Amp charge current in one unit. `the best part? All the smarts you need have already been integrated into the circuit board. Not that we doubted your ability to DIY, but why spend countless hours when you can spend only a few? That’s more time enjoying your build and less time pulling your hair out. Protect the hair at all costs.

EGON DC-Hub Dual Power Distribution Hub is the new, brilliant way to install a 12/24V DC Dual Battery Systems with up to 100Amp supply from 2 x DC/DC chargers.

Description

THIS is a remarkable, new cost and time-saving device is called the DC-Hub Dual. Imagine a simple, extremely robust DC input/output fuse box combination board that reduces workshop time by a large factor, but also does away with the need for specialist expertise when building DC electric setups.

All components are wired to this single central hub, including AC chargers, solar panels, and DC chargers. From the same unit, wires run to all accessories, such as fridges, lights, compressors, and more. This can all be done without the need for crimps, lugs, shrinks, or expertise. All the time-consuming work is done for you!

The EGON DC-Hub Dual permits a configuration that combines two different start batteries with two alternators, even if they are producing different charge voltages.

It connects all elements of a DC installation, including first battery, auxiliary batteries, DC-DC, alternator, solar, and other charging devices.

The highest quality connectors mean that soldered or crimped lugs, as well as heat-shrink, are unnecessary.

This reduces labour time and the need for expertise and speeds up fault finding and warranty comebacks.

Tested to Destruction

We proved that our goal to over-engineer the DC-Hub Dual worked, putting massive current over-loads through the connections and PC board, over extended time periods, resulted in no warping, melting or any significant damage of any kind. We abused it beyond anything that could happen in the real world, and it came back smiling. And amazingly, even though we tested one to destruction - it still works faultlessly. We could not destroy it!

Fuses

The DC-Hub Dual is not supplied with any fuses.

Connector Explanation

  • The house (aux) battery (AGM, LiFePO4, flooded lead acid, etc.) connects to connector P3 and requires an external 150A fuse at the house battery bank. Size doesn’t matter - DC-Hub doesn’t discriminate.

  • Your start battery connects to P8 and P14 and needs an external fuse at the start battery of your vehicle.

    • You can choose to supply the DC Hub-Dual from just one start battery to both DC/DC chargers or use two different start batteries which can also be supplied from two different alternators with different supply voltage, in case your DC/DC chargers are compatible with these voltages.

  • Connect solar panels to P7 and P13.

  • Your P8 and P7 positive cables link to P6 and P13 and P14 positive cables link to P12 for a seamless connection to both your DC/DC chargers with integrated MPPT controller (i.e. Redarc BCDC range, Enerdrive DC/DC, etc.). These can all be connected to P5 and P11 with charger output and ground, and connector P6 and P12 for solar and start battery input.

  • What about the ground connections?! Simple. They’re all linked on the circuit board.

  • The most important part. The fridge! Well, all of your loads (compressors, fridges, lights, charge ports, etc.) can now be connected to your remaining connectors. They’ll even automatically connect to the house battery. Simple!

  • Handy hint from the experts: The connectors P4, P9, P10 and the 25A Outputs can also be used as Inputs to connect chargers, solar regulators, etc…

  • Connectors P4 and P5 and P11 can handle a constant 80A load. To prevent the Maxi Fuses from overheating please use two Maxi Fuses. Also note not to exceed the total load of 150A for the DC-Hub Dual to the House battery.

    • Example: When connecting a DC/DC charger to connector P5 that requires a 60A fuse, insert 2 x 30A fuses into fuse holder F13 and F13A. And when connecting a DC/DC charger to connector P11 that requires a 60A fuse, insert 2 x 30A fuses into fuse holder F15 and F15A.

    • Do the same with connections to connector P4 and use the fuse holder F14 and F14A.

  • Connectors P9 and P10 can only handle 40A constant load or 80A intermittent load.

    • Currents of 40A must not be exceeded for more than 10 minutes at a duty cycle of 50% (10 minutes on / 10 minutes off) to allow the contacts to cool.

ATTENTION:

  • Fuses are meant to fit tightly in the sockets on the DC-Hub Board.

  • Do not attempt to pry open the receiving sockets to make fuses easier to remove.

  • The tight nature of the fuse in their holders ensures minimal voltage-drop.

  • If they become loose-fitting, the connection may heat up, and voltage drop and efficiency will be reduced and damage can occur due to heat build up on the fuse holder.

  • If you find a fuse that is not tight in its holder, we recommend using pliers, gently squeezing the connector before inserting the fuse.

  • Pay special attention to the DCDC charger connection fuse (P5).

Installation Guides

The board is marked with input instructions, and every unit comes with an installation guide. These guides are backed up by installation videos on our YouTube channel.

Tightening Torque Settings & Connector Maintenance

It is extremely important to tighten the screw terminals on the DC-Hub connectors properly. Please use the following torque settings to tighten the connectors:

  • 150A connector: 3.5Nm

  • 80A / 40A connectors: 1.5Nm

  • 25A connectors: 0.6Nm

Ensure all unused clamps are tightened to prevent rattling from the circuit board. In high-vibration applications, make sure you check the screw tensions as part of your regular vehicle maintenance schedule.

Cable Ratings and Fuses

The following chart can be used as a guideline for picking the right cable size for your application. We also integrated a guide for picking the right lug and heat shrink size. Never exceed the amp rating for a cable. Always use a fuse that is smaller or equal to the maximum current carrying capability of the cable that you are using. Never exceed the manufacturer's recommended fuse rating for the appliance you are connecting.
