Please Note: This is a recreational power distribution unit, and not a jump starter, do not attempt to jump start any vehicle with the unit, as this will void warranty.
The Unit Battery and BMS are set to provide up to 80% DOD – or 80 percent of the total rating of the unit, before unit shuts down – Discharged voltage between 8.4-8.8 volt Fully Charged at 12.4-12.6 Volt. It is set at 80% to support the longevity of the battery life.
Do Not use this unit if you do not read the instructions. The Nomad PDU comes with a 12-month manufacturer’s warranty under normal use, failure to follow instructions, adhere to ratings and loads will void warranty
To protect the unit and ensure you do not void the warranty, please read the below.
Do Not use the PDU to jump start a vehicle (Do Not) this could cause fire or swelling of the battery as it is not designed for this purpose, it is clear if this has been done.
• Do Not run the PDU’s in serial (24 volt)
• Do Not submerse in water or subject to water saturation.
• Do Not attempt to modify the product unless given specific permission from manufacturer or warranty is void.
• Do Not use fuses rated higher than recommended in charging options.
• Do Not drill holes into the casing as you may drill into the battery chemistry.
• Do Not charge unit at any higher rate than advised – unregulated max charge rate 10amp, regulated 25amp
• Do Not Charge with both unregulated and regulated power sources at the same time, resulting in overcharging and BMS damage, use one or the other at any time.
• Do not try and use DCDC chargers designed for AGM/Lead Acid or Gel, we have an optional Lithium specific DCDC option available.
• Read All Instructions to maximise life of unit. Typical Operating Specifications do’s and don’ts
• Most Important is to fully charge the Unit before operation to maximise efficiency and before installing into a vehicle, or trickle charging.
• Total output across entire unit at any time cannot exceed 20-amp output, if unit trips out then remove the load and turn the unit off and then back on, plug in the AC/DC charger or solar to trip the reset, the lights and LED will come back on.
• MAXIMUM CHARGE RATES – NEW MAXIMUM REGULATED CHARGE RATE “25amp” – (RED CIRCLED ANDERSON), The UNREGULATED SOLAR POLES RED AND BLACK have Max Charge Rate of “10amp”,, do not exceed these charge rates or the BMS and or MPPT can be damaged. MPPT Rated 10amp.
• Accessories Note: You Can Run Your Fridge While Charging... many accessories such as fridges will work with voltage of 10.5-or 11volt through to 12.6 so fully charge before using on accessories to determine active operational time – unit will shut down at 8.4 -8.8 volt but your accessory may shut down when voltage has dropped per the accessory operating range. • Each output is rated to 10amp max except the Green Anderson which is Rated at 20amp output -the 2.1mm jacks are suitable for all your lighting - Please Note: Maximum Unit output combined is 20amp at any one time
• Dual Screens for your convenience - First screen for current voltage and charge, second screen tells you how much your accessories are drawing from the unit.
• Red Light charging indicator will indicate unit being charged, the light can go on and off when floating at full charge.
• OVERCHARGE PROTECTION- If PDU is overcharged, ie you have tried charging at higher rate than specification, the PDU has Battery protection and will trip and bleed off the current, the unit will then not take on charge – you will need to draw more than 1 amp from the unit to reset the charging – view the tutorial on nomadpdu.com.au. DEAD SHORT PROTECTION – If you have a dead short, the until will trip out. To reset disconnect the load or fault, turn off then back on and plug in a power source, this will reset the unit. You can view a tutorial on this at noadpdu.com.au
• 8-amp AC/DC Charger – can be used with a suitable inverter in vehicle, pure sine is preferred, however most modified wave can be used, test your inverter with retailer.
• Un-Regulated Solar - Solar charging options – unit can accept unregulated solar panel directly connected to the red and black poles. 10AMP MAX INPUT check your panel output ratings internal MPPT is rated 10amp 8-32 volt.
• Regulated Solar Panel – Maximum charge rate into Red circled Anderson is 25amp 12 volt, do not exceed.
• Dual USB ports – Maximum 1.5 amp (typically can charge 2 Iphones, or android phones, Camera etc)
• 2 by Ciga, 1 by Anderson (NEW 20amp output) 1 by Engel socket, 2 by 2.1 jack configuration. Accessory adapters available from your supplier.
Do Not use the PDU to jump start a vehicle (Do Not) this could cause fire or swelling of the battery as it is not designed for this purpose
NOMAD PDU comes with a 12-month manufacturer’s warranty under normal use – see above
Battery Behaviour: PLEASE NOTE: When your Nomad PDU is low in voltage, the unit will draw as much current as it can get, this is important to remember if you are trickle feeding from the car, it will draw as much current as available and will exceed 30-40 amp if it is not fused and you will damage the unit. There is no benefit to charge at higher rates, if you exceed the charge rates you will damage the unit and void warranty.
Do Not use this unit if you do not read the instructions WARRANTY
The Nomad PDU comes with a 12-month manufacturer’s warranty. To protect the unit and ensure you do not void the warranty, please read the below.
“Charging the Nomad” General
• Regulated Charge -The RED Anderson Connection on the PDU is for Regulated Charge only – NOW WITH 25amp charging Maximum. Your Solar panel will either be regulated or unregulated (if the panel has an MPPT Controller on the back) it is regulated and plug into the RED ANDERSON Port to charge, you also plug in your AC/DC 8-amp charger into this port as-well.
• Unregulated Charge – typically from a solar panel without an MPPT Controller, your panel will give you that information, unregulated solar connects to the solar Poles Red and Black (Maximum 10amp charge) – PLEASE ADHERE TO THIS RATING.
• Panel Size Reg or Unregulated – quite simply look for a panel that has a max output of 25amp if a panel with its own regulator, then PLUG INTO RED CIRCLED ANDERSON, and if Unregulated Solar Panel (Panel only) – Maximum charge rate is 10amp 8-32V, connect to solar poles (BLACK AND RED) this goes through an internal MPPT controller that will convert to a Lithium Charge. MAX 10AMP rated panel only – an unregulated panel of 120-150 watt is well sufficient.
Charging From Car: • Trickle Charging from Car – FIRSTLY AND MOST IMPORTANLTY, ALWAYS FULLY CHARGE YOUR NOMAD BEFORE TRIP, AS IT WILL ALWAYS USE LESS CURRENT AND DRAW FROM THE VEHICLE TO KEEP FULL.
• Preferred Vehicle charging method is by DCDC Charger which will charge with lithium specific algorithm. – the optional 10amp or 20amp Lithium DCDC in car charger that can be purchased will regulate charge to 10amp or 20amp and provides a lithium specific charge. You must ensure that your wiring is rated more than 20amp in the vehicle to ciga socket, if not , the kit provides all the upgraded wiring to 6mm 30+amp. You must disconnect the Nomad when the vehicle has stopped running, or it will draw power from the crank. UNLESS you add your own low voltage cut out or VSR (Speak to auto electrician) that switch will only allow current to go through to the Nomad PDU (or AUX Battery) when the crank battery is being charged by the alternator and the crank is over 13Volt or set voltage. That ensures when the car is off and the crank voltage drops, that the switch will disconnect charge to the Nomad. This switch is not provided in the kit as most people simply disconnect from the car at night.
You plug the DCDC charger into the Regulated input (Red Circled 25amp Input, the DCDC module charges constant 10 or 20amp) Installing a DCDC directions are also included in this instruction leaf. If you are going to use an existing Ciga plug and socket, then ensure they are rated 10-15amp or more minimum.
• Solar Panel Roof mounted – You may choose to connect a solar panel to the unit whilst driving. Simply connect the panel during the day while driving or at camp. You can use either unregulated panel (max 10 amp) charge rate or regulated panel (up to 25amp) 12 volt. Please Note, having a higher charge rate is not necessarily better for the unit and once the unit is fully charged it won’t accept any more charge. For example, if the unit is full at midday, then by 5 pm it will still be full. A 40-litre efficient fridge may use 15amp overnight, the Nomad will charge at 5-9amp (depending on panel) for the daylight hours even if a
bit of overcast, so the unit would still be full each night, and the cycle starts again.
• Can you charge with both DCDC and Solar at the same time? – No, please choose one or the other option, as this also contributes to the life of the unit. The question that needs to be asked is what are the loads the unit will be using, as 10amp via DCDC or solar is typically efficient. Most people run the DCDC while driving then connect the solar panel when camping.
• Make up adapter leads if you are going to put under a seat or out of the way, then you can simply plug in Andersons to whatever charge source you choose
• Inverter: Simple in car charging can also be done by plugging in a 150-300-watt inverter, and then plug in the AC/DC amp charger into the inverter, then it is regulated to the RED ANDERSON CHARGE INPUT. The charger will draw 109 watts when running from an inverter – please check your vehicle wiring is rated at minimum of 10amp, IE your ciga socket should tell you the rating of the socket. Check the inverter is compatible, preferable pure sine. Please check if using a modified inverter at time of purchase as some inverters can trip a fault light due to circuitry in the inverter. Do not run a 150-watt inverter for more than a few hours at a time.
You can run your fridges etc while the unit is charging
