Home / Australia guides / Essential household services / Communications during outages: Small business premises
Australia planning guidance for a specific property and load boundary. Distinguish stock protection from permission to trade. H2OME remains in early development.
List the full connection chain: router, optical terminal if present, handset base, mobile charging and any local network equipment. A battery in a laptop does not power the router, and a powered router does not guarantee that upstream infrastructure or a mobile cell site is operating.
Keep contact details and essential information available without internet access. Choose a fallback that does not depend on the same local network, and test it under ordinary conditions. Avoid interpreting successful local equipment operation as a guarantee of service availability.
Process equipment, large refrigeration, compressors and all-day trading should not be implied by a small essential-load calculation.
A shop or service office needs to distinguish safe closure from continued trading. Refrigeration, transaction equipment and security have different consequences, and a powered till does not ensure payment networks work.
In small business premises, identify whether the router, terminal and handset are already counted in 0.46 kW assumed base demand. The additional 18 W example is only for equipment outside that base set; document the contact route that still works if the powered local network loses upstream service.
Distinguish stock protection from permission to trade. Any food, workplace or regulated service obligation needs its own contingency assessment. A development-stage product is not evidence that a business can continue trading safely.
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 small business premises, assume the selected base loads average 0.46 kW for 6 hours: 0.46 × 6 = 2.76 kWh. Separately, an extra handset base and network device draws an assumed 18 W for 12 hours: (18 ÷ 1,000) × 12 = 0.216 kWh. The combined illustrative demand is 2.976 kWh.
Low device demand can support a modest worksheet, but external network availability remains outside the system.
For arithmetic only, if the complete storage chain had a hypothetical 30% round-trip efficiency, delivering 2.976 kWh would require 2.976 ÷ 0.30 = 9.92 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: 6 hours. Extra illustrative load: An extra handset base and network device, 18 W for 12 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 2.976 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.
