A blackout changes the priorities in a house very quickly. The lights are the easy part. Keeping food cold, phones charged, internet running, medication safe and a few essential appliances operating is what matters. Knowing how to prepare blackout backup before the weather turns or the grid goes down gives you options without the noise, fumes and last-minute scramble of a petrol generator.
The best backup setup is not necessarily the biggest one. It is the one sized around the loads you genuinely need, stored ready to use and simple enough for everyone in the household to operate safely.
Start with the essentials, not every appliance
Trying to run a whole home from a portable battery can turn a sensible plan into an expensive one. During an outage, focus on the equipment that protects food, communication, comfort and safety.
For most homes, that means a fridge or freezer, a few LED lights, mobile phones, a modem and perhaps a laptop. Depending on your circumstances, it could also include a CPAP machine, medical equipment, a small fan, a circulation pump, a television or an electric blanket. Rural properties may need power for a pressure pump, gate system or livestock monitoring equipment.
Write down each appliance you want available and find its wattage on the label, power pack or manual. Then consider how many hours it needs to run. A 10-watt LED light used for five hours consumes 50 watt-hours. A 100-watt fridge running intermittently may use far less than 100 watts for every hour, but it also has a high start-up surge when the compressor kicks in.
This is where many backup plans fall short. They account for energy capacity but overlook inverter output. Your power station needs enough continuous power for the appliance while it runs, plus enough surge capacity to start motors in fridges, freezers and pumps.
How to prepare blackout backup around your real loads
Once you know the essentials, calculate a realistic daily energy target in watt-hours. Add each appliance's wattage multiplied by expected hours of use, then allow a margin for losses and unexpected use. A plan requiring 1,000Wh a day should not be built around a 1,000Wh battery if you need reliable overnight operation.
A small power station may be ideal for phones, lighting, laptops and a modem. A larger lithium power station is better suited to refrigerator backup, longer runtimes and several appliances at once. If you need to support critical loads over multiple days, battery capacity and recharge options matter more than a headline inverter number.
Think in terms of priority tiers. Your first tier might be the fridge, communication and lighting. Your second tier could be a fan, entertainment and charging tools. High-draw appliances such as kettles, toasters, electric heaters, air fryers and clothes dryers usually do not belong in a portable blackout plan. They drain batteries quickly and can exceed the inverter's output.
A kettle may draw 2,000 watts or more. Heating one cup of water is possible on some larger systems, but it is rarely the best use of stored energy when the outage could last all night. A gas cooktop, barbecue or camp stove used safely outdoors is often a far more practical option for meals.
Battery backup or petrol generator?
A lithium power station is the straightforward choice for indoor essentials and overnight use. It is quiet, produces no exhaust fumes and can sit near the appliance it is powering, provided it is kept dry, ventilated and used in line with its instructions. You can run a modem and lights in the evening without upsetting the household or the neighbours.
Petrol inverter generators still have a place where high loads or extended poor-weather outages make fuel-based generation practical. They are useful for certain pumps, larger tools or recharging a battery bank when solar production is limited. But they require fuel storage, regular servicing and safe outdoor placement. Never run a petrol generator in a house, garage, shed, caravan annex or near open windows. Carbon monoxide is odourless and can be fatal.
For many households, the strongest approach is a lithium power station for quiet, immediate essentials, backed by solar for daytime recharging. A petrol inverter generator can be a secondary option where the property, load profile and outage risk justify it.
Add solar for outages that last longer
A battery gets you through the first hours. Solar gives you a chance to keep going.
Portable solar panels are particularly useful during daylight outages because they can replace the energy used overnight. Panel output varies with weather, panel angle, season, shade and heat, so do not plan around the maximum rating printed on the panel. A 200-watt panel will not necessarily deliver 200 watts for every hour of the day.
Set panels where they receive clear sun and adjust their angle as conditions change if practical. Even partial shade from a tree branch, antenna or roofline can sharply reduce production. Keep cable runs tidy, connections dry and panels secured against wind. Do not leave portable panels where they can be damaged by vehicles, pets or passing foot traffic.
If blackouts are common in your area, practise deploying the solar setup on a normal day. Learn which part of the yard gets the best winter sun, how long your cables need to be and how much energy your key loads consume. A system tested in calm weather is much easier to use when rain is coming sideways and the power has already failed.
Protect the fridge, food and communications
A closed fridge will usually keep food cold for several hours, while a full freezer can hold temperature for much longer if left shut. Avoid opening doors repeatedly just to check. Connect the fridge to backup power when needed, then let it cycle normally rather than assuming it must run constantly.
Your NBN equipment and modem are low-power loads that make a major difference during an outage. If the local network is operating, a modest battery can keep internet and Wi-Fi available for many hours. Charge phones early, keep a power bank handy and download important contact details, maps and weather information before severe conditions arrive.
For homes relying on electric cooking, water pumps or electric garage doors, have a manual alternative. Keep drinking water on hand, know how to release the garage door manually and store a torch near the bed rather than relying on a mobile phone torch. Head torches are especially useful because they leave both hands free.
Use backup power safely
Portable power stations are designed to run appliances plugged directly into their outlets. Do not try to feed one into household wiring through a wall socket or an improvised lead. This can energise wiring unexpectedly, damage equipment and place line workers at serious risk.
If you want selected house circuits powered during an outage, speak with a licensed electrician about a compliant changeover switch or dedicated backup inlet. This is the right path for fixed systems, pumps and hardwired loads. It also makes clear which circuits are supported and prevents accidental overloads.
Keep lithium batteries away from standing water, direct rain and extreme heat. Store them partly charged if they will sit unused for long periods, then check their charge level regularly. Recharge after use rather than putting the system away flat. Test leads, solar connectors and AC outlets for wear before storm season.
Households with life-support equipment should have a more detailed plan than portable backup alone. Contact the equipment provider and electricity retailer about their outage procedures, maintain any required emergency backup and ensure family members know what to do if power cannot be restored. For immediate danger, call 000.
Build a kit you can use in the dark
Keep your blackout gear together rather than scattered through cupboards. Alongside your charged power station, store compatible charging cables, a power board rated for the intended load, LED lights, a head torch, spare batteries, a radio, drinking water and basic first-aid supplies. Label the cables for the modem, fridge and solar input so there is no guesswork.
At Mobile Power Solutions, ESCAPE power stations are designed and assembled in Australia for the sort of practical, independent power needs that arise at home, on the road and well beyond the grid. The right size depends on your appliances, expected outage length and whether solar recharging is available.
A blackout plan earns its value before the blackout. Charge the battery, test the fridge runtime, practise setting up solar and make decisions about essential loads while the lights are still on. When the grid fails, you will know exactly what to power first.
