Best For Entry Level Use: EcoFlow DELTA 2

The EcoFlow DELTA 2 is a fantastic entry-level home backup option. It’s ultra quiet and boasts new LiFeoPO4 batteries that aren’t prone to toxic off-gassing or leaking acids like old lead-acid models and aren’t prone to thermal runaway of older lithium-ion batteries, making it the safest money can buy. 

It’s also robust enough to power 90% of household appliances, including refrigerators, TVs, and coffeemakers. Even if you run out of power, it recharges fully in just 2.3 hours using clean solar energy so you can get up and running once again. Of course, you can also use it without solar panels and recharge it when the grid comes back on.

Since it only weighs 12 kg, it’s also lightweight enough to carry with you on your next caravanning or tent adventure, making it one of the most versatile backup options you can buy.

Choosing the Best Generator for Home Backup Power in Australia

Choosing the best home backup power for your family depends on several factors unique to your family’s needs.

Capacity

The battery backup size you need is based entirely on your energy needs. Make sure you calculate your household kWh usage to determine the best product for you. Always choose an option with at least a bit more capacity than you currently need in case your needs increase. 

Functionality

How are you using your battery backup? Do you just need it for a few appliances when the grid goes down, or do you need to run many appliances during extended blackouts? Do you want a whole-home backup, do you want to go off-grid, or do you want a portable unit to bring with you on outdoor adventures? 

These are important things to consider when buying a system since the capacity and weight vary significantly. Other factors are the types of outlet ports (AC, USB, USB-C, DC) they offer, as smaller or cheaper ones have fewer ports. 

Maintenance

Maintenance used to be a significant factor, and it still is if you opt for a fossil fuel generator, as these will need oil and filter changes and constant refuelling to keep your appliances running.

Similarly, lead-acid batteries also require maintenance to keep them running optimally. In contrast, EcoFlow’s Portable Power Stations that use the new LiFePO4 batteries require no maintenance to keep them at their best. 

Noise

Again, the noise was often a consideration in the past since fossil fuel generators are very noisy, so close neighbours may be bothered by them. Solar generators using batteries are ultra quiet, so no need to worry about noise anymore.

Frequently Asked Questions

Final Thoughts

Now, you should have all the information you need to choose the best home backup generator for your family. Consider your household energy needs and what you want from your backup power system. Do you want it to run a few appliances during an occasional blackout, or do you have many appliances, or are you prone to extended blackouts? The answers to those questions will help you decide the best system. 

No matter what size of system you need, EcoFlow’s DELTA series portable power stations offer versatile options that will allow you to find the perfect one.
