Home / Australia guides / Load planning / Appliance duty cycles: Farm residence
Australia planning guidance for a specific property and load boundary. Exclude production machinery from domestic totals. H2OME remains in early development.
A thermostat-controlled load switches between operating states. Multiplying its maximum input by every hour can exaggerate consumption, while measuring only a quiet interval can understate it. Log a complete representative operating cycle and note ambient conditions, door openings, water use or other factors that change the cycle.
Time-averaged power is appropriate for an energy worksheet but not for protection or peak output checks. Keep the active-state input and measured operating fraction visible. A changed use pattern during an outage can make yesterday's duty-cycle average irrelevant.
Milking plant, large refrigeration, irrigation and workshop machinery need a separately engineered supply assessment.
The residence may sit beside machinery that exceeds a small household system. Domestic continuity and farm production must be separate scopes; sharing a driveway does not make a large shed a household load.
Review how domestic refrigeration was averaged for a farm residence. If occupants change the operating routine during the 18-hour base window, replace the base average rather than retaining it and merely adding the extra appliance.
Exclude production machinery from domestic totals. H2OME has a 10 kW design target, not a demonstrated farm power rating. Large production loads may be outside its scope entirely; no multi-unit capability is assumed here.
All numbers below are hypothetical teaching inputs, not measured appliance specifications or product performance. The topic-specific extra load is separate from the base set; omit it if your real inventory already counts it. This worksheet does not include conversion overhead, protection design or a contingency allowance.
For a farm residence, assume the selected base loads average 0.32 kW for 18 hours: 0.32 × 18 = 5.76 kWh. Separately, an extra controlled appliance averaged to 100 w draws an assumed 100 W for 10 hours: (100 ÷ 1,000) × 10 = 1 kWh. The combined illustrative demand is 6.76 kWh.
The assumed average must be supported by measurements; its active-state demand could be higher.
For arithmetic only, if the complete storage chain had a hypothetical 30% round-trip efficiency, delivering 6.76 kWh would require 6.76 ÷ 0.30 = 22.5333 kWh of charging input. This is not a measured H2OME efficiency or recovery result. Ongoing demand during charging would add to the required input.
Base operating window: 18 hours. Extra illustrative load: An extra controlled appliance averaged to 100 W, 100 W for 10 hours. Replace every input with a measured or professionally established value.
In Australia, check connection questions with your electricity retailer and distributor. Use electrical professionals holding the licence required in your state or territory, and ask the local council about relevant siting, building and water-use requirements. Energy Made Easy covers New South Wales, Queensland, South Australia, Tasmania and the Australian Capital Territory; outside those jurisdictions, check the relevant state or territory consumer energy comparison resource. Compare your actual tariff and charging window, not an assumed national rate. This guide does not claim to know a particular state's approval process.
For life support equipment in Australia, keep life support registration current with the electricity retailer or distributor as applicable and confirm how the other party is notified. Follow your clinician and equipment provider's contingency plan. Registration is not a guarantee of continuous electricity, and H2OME cannot replace an independent medical contingency.
H2OME is in early development. Its 10 kW output figure is a design target, not a proven specification. There is no confirmed price, certification, commercial availability or guaranteed runtime in this guide.
Hydrogen is an energy store, not free energy. Grid input, wind and micro-hydro are the charging options considered here. Each requires its own supply assessment. Do not install hydrogen equipment, modify fixed wiring, bypass protection or improvise a connection from this guide.
These official resources provide energy, consumer and technical background. They are not endorsements of H2OME, proof of its performance or a substitute for site-specific professional advice.

No. The 6.76 kWh total is an illustrative demand worksheet, not a runtime result. Actual appliance measurements, usable storage output, starting demand, conversion overhead and reserve limits are needed. The 10 kW design target is not demonstrated output capability.

Ask us about H2OME, tell us about your property or register your interest in the proposed system. We are in early development. No payment or purchase commitment; contacting us does not guarantee a pilot installation.
