8 Power Supply Solutions for ZERO BREEZE Mark2 AC
1. MK2 Battery for Single Battery Power Supply
1 x MK2 AC
1 x MK2 Battery
1 x Connection cable for MK2 AC and MK2 Battery
How to connect:
Connect the MK2 AC and MK2 battery using the connection cable.What effects does it bring:The MK2 Battery has a capacity of 840Wh, and the maximum power of the MK2 AC is 240W, with a minimum power of 100W (depending on environmental temperature and humidity, working mode, and setup). The working time is approximately 3.5 to 8.4 hours, calculated by dividing the battery capacity by the power required for operation:
Ultra-fast cooling mode: 840Wh/240W=3.5h
Cooling mode: 840Wh/150W=5.6h
Sleep mode: 840Wh/100W=8.4h
Fan mode: 840Wh/20W=42h
2. Two MK2 Batteries for Dual Battery Power Supply
2 x MK2 Batteries
1 x Power Extension Dock
3. Two MK2 batteries with a 240W adapter to achieve dual battery charge and discharge at the same time
Items that are needed:
1 x MK2 AC
2 x MK2 batteries
1 x Power Extension Dock
1 x 240W adapter
How to connect:
Use the Power Extension Dock to connect the MK2 AC and two MK2 batteries, and connect the 240W adapter at the same time.
What effect does it bring:
By achieving dual battery parallel power supply to the MK2 air conditioner, and charging with the 240W adapter, each battery can receive up to 120W of charging power, meeting the discharge power required by each battery, ensuring that the MK2 batteries are always fully charged and the MK2 air conditioner always works.
Note:
The 240W adapter needs to be plugged into a wall outlet or a mobile energy storage power source that can provide more than 240W.
4. MK2 Battery with Car Cigarette Lighter Charging
Items that are needed:
1 x MK2 AC
1 x MK2 battery
1 x Power Extension Dock
1 x 12V to 24V Converter
How to connect:
Use the Power Extension Dock to connect the MK2 AC and one MK2 battery together, and connect the 12V to 24V Converter. Insert it into the car cigarette lighter to charge the MK2 battery.
By providing power to the MK2 AC from a single battery while also charging it through the car cigarette lighter, it can provide a maximum charging power of 120W to the battery. If the power consumption of the AC is lower than 120W, it can ensure that the MK2 battery is always fully charged, and the MK2 AC is always working. If the power consumption of the AC is high, such as reaching up to 240W, a fully charged battery can maintain the AC at maximum power for 7 hours while being charged simultaneously.
Considering that the output voltage of a conventional car cigarette lighter is 12V, and the output power is between 120W and 180W, we recommend using only one battery in this case. If two batteries are used in parallel, they will demand an output power of 240W from the cigarette lighter when charging, which could cause the cigarette lighter fuse to blow.
For the same reason, we do not recommend using the MK2 AC and the 12V to 24V Converter to work directly from the car cigarette lighter. When the power consumption of the AC exceeds the power output that the cigarette lighter can provide, it may cause the cigarette lighter fuse to blow, and the AC will not work.
5. Two MK2 batteries with solar power to achieve dual battery charging and discharging
Items that are needed:
1 x MK2 AC
2 x MK2 batteries
1 x Power Extension Dock
2 x 100W solar panels (or 3 panels)
1 x solar panel parallel connection cable
1 x MC4 to GX16-4 (1+, 3-, 2, 4 hanging) cable
How to connect:
Use the Power Extension Dock to connect the MK2 AC and the two MK2 batteries. Use the parallel connection cable to connect the two 100W solar panels in parallel, and connect the output to the input of the Power Extension Dock using the MC4 to GX16-4 cable.
What effect does it bring:
By achieving dual battery connection for the MK2 air conditioner, and charging the batteries using a 200W solar panel under good lighting conditions, it is possible to output a charging power of 160W-180W. This can ensure that the MK2 batteries are always fully charged while the MK2 air conditioner continues to operate in normal cooling mode.
Note:
If you want to use more or higher power solar panels, you need to pay attention to the solar panel output voltage. It needs to be between 20-24V, as lower voltage may not charge the batteries and higher voltage may damage them.
There is no limit to output power, but each battery can only receive a maximum of 120W-130W charging power, and both batteries together can receive a total of 240-260W charging power.
6. Two MK2 batteries with a 12V battery bank charging
Items that are needed:
Hi @Colin, 12-24V converter will be more efficient. What you need to do is just connecting the Mark2 AC with 12V power source through the 12-24V converter without any extra power adapter. However, 12V to 240V inverter typically works by converting electricity from DC into AC , and then connect with the Mark 2 through a power adapter, which consumes a significant amount of energy.
The Mark 2 could draw 100-240W power from 12V to 240V inverter. Considering energy loss, the actual power consumption could exceed 240W.
And 12-24v converter current requirement is about 6-27A. (The voltage range of the 12V to 24V converter is 9-16V, current can be calculated by dividing the power consumption by the voltage range)
Hi, very useful article and well done. When you say « If faster charging while driving is important and you want to limit the stress on your alternator, a DC to DC charger that boosts the voltage of your vehicle charging system to optimally charge the house battery while limiting the maximum current to avoid overloading the alternator may be worth it » does it mean that the need of a adjustable Voltage Regulator for Alternator is useless in this case? I have a solid 13,7 13,9 volt from my alternator.
G’day, I’m wanting to buy a Mark2 zero Breeze unit. In my camper I have a 12v 150ah lithium battery and also I have a spare 24v 110ah lithium battery. Can I use the 24v battery to power the Zero Breeze or would I need to use the 12v and one of your 12v to 24v converters?
My preference would be if i could run it straight off the 24v battery I have.
Good morning, I would like to run the Zero breeze from my caravan batteries what method would you consider the most efficient, 12v to 24v converter or 12v to 240v inverter ? in either case could you tell me the 12v to 24v converter current amperage requirements ? and for the 12v 240v inverter size Wattage size ? please.
Thank you for your time
