Phase 6

When using any domestic 240V appliance the use of a good battery bank of 12V / 24V DC storage and a DC to AC inverter is the only why to run these items. It's important you do your maths when designing the system. Ask yourself questions like: Do I need the washing machine on at the same time I'm using the electric oven cooking ? These will all have a massive effect on the load requirements of your build and can result in a very expensive system. I always advise to run one item at a time and leave good time in between for any possible solar recharge to happen. Unless you are parked on a campsite with mains hookup then this doesn't really apply.

Watts ÷ Volts(24V) = Ah

Ah x Usage(Hours) = Ah/day

Washer Dryer: ±2000W 83.33Ah

Usage: (1/2 hour per day) = 41.66Ah/day

Usage: (1/2 hour per day) = 4.16Ah/day

Kettle: ±3,000W 125Ah

Usage: (3 x per day for 4 minutes) = 8.33Ah/day

Toaster ±700W 29.16Ah

Usage: (1x per day for 4 minutes) = 1.94Ah/day

Truma Aventa comfort air conditioning unit ±1,000W 41.66Ah

Most camper, or off grid appliances are designed to run on 12V / 24V. This makes things a lot better to run and maintain running for a considerable amount of time. It's often best to use the same voltage as the donor vehicle, in my case its 24V. Although I will be running 12V as well for 24V items.

Watts ÷ Volts(24V) = Ah

Ah x Usage(Hours) = Ah/day

Fridge Freezer: ±22W .91Ah

Usage: (24/7) = 22Ah/day

Eberspacher D5WSC heater (Heat towel rail in bathroom): ±40W 1.66Ah

Usage: (1hour per day) = 40Ah/day

Fresh water water drain valve: ±2W

Grey water grey drain valve: ±2W

Watts = 66W

Amp Hours = 2.57Ah

Amp Hour/Day = 66Ah/day

A lot of items can be run off 12V in a camper from lights to fridges. Some 240V items can be converted to run on 12V as well.

Watts ÷ Volts(24V) = Ah

Ah x Usage(Hours) = Ah/day

Truma Combo D6E 10litre diesel boiler: ±1,500W 62.5Ah

Usage: (1 day per month)

Usage: (1/2 hour per day) = .62Ah/day

UV Water purification: ±100W 4.16Ah

Usage: (1/2 hour per day) = 2.08Ah/day

Water pump: ±60W 2.5Ah

Usage: (1 hour per day) = 2.5Ah/day

Bathroom extractor fan: ±30W 1.25Ah

Usage: (1/2 hour per day) = .62Ah/day

WooWoo Separett Tiny Compost toilet: ±1.5W .06Ah

Usage: (1/2 hour per day) = .03Ah/day

Teltonika RUT956 WiFi: ± 3W .12Ah

Usage: (24/7 Standby) = 3Ah/day

Usage: (2 hours per day) = 4.16Ah/day

Outside LED Lights: x8 ±80W 3.3Ah

Usage: (1 hour per day) = 3.3Ah/day

3 Way Solenoid Valve ( Hot water boiler selector): ±2W

Watts = 1,934.5W

Amp Hours = 80.55Ah

Amp Hour/Day = 22.97Ah/day

As mentioned I will converting a few of the 240V appliances to run of 12V or less in the future. You will be surprised as to how many 240V appliances are actually running on just 12V DC or less. This will have a massive saving on load capacity in the future. These will require varies DC step down regulators in different voltages and wattage loads. I will also install enough 12V fuse boxes to allow for this transition, as it will be wise to still have each item fused. WARNING - Seek professional help when working with electrics no matter the voltage.
