What Do You Need Your Solar Generator For?

With so many different sizes, watts, and capacities on the market today, solar generators for houses have never been more versatile. Gone are the days of clunky, loud, gas-grazing standby generators of yesteryear. Let’s take a look at some of the applications that people use their solar generators for:

Solar Generator for General Home Use

Make the most of your free collected solar energy throughout the day and power up your appliances.

Solar helps you to cut your electricity bills, keeps you partly or fully independent of the main grid, and reduces your carbon footprint.

Solar Generator for Home Backup Emergencies

In the event of a blackout, a solar generator with the correct capacity for your daily usage will be your blessing. For maximum usage, it’s best to have a power outage plan to gauge the appliances you’ll need to charge up the most.

What To Look for When Choosing a Solar Generator for Your Home

Listed below are the top specs to look out for in a solar power generator for home use to better arm you with more buying power.


Solar generators come in all different capacities, and you’ll want one that is just enough for your home energy usage. For instance, use a small solar generator like a DELTA mini (1400W) + 160W solar panel and charge up smaller devices like iPads, phones, laptops, drones, and cameras if you’re a freelance photographer or hobbyist who frequently needs to charge their devices.

Or, if you’re a family of 4-5 with piles of clothing to wash and dry throughout the week and are super worried about your soaring energy bills, use a large solar generator like a DELTA Pro + 400W solar panel for a massive 3.5kWh capacity to help lighten the load.

Choosing a capacity that’s right for your home ensures that you’re either not wasting time charging your device for watts you don’t need or, conversely, are not running out of power to charge larger appliances.

Output determines how much power a battery generator for a home uses. It’s important to know what output each of your appliances uses and the total power they eat when used simultaneously. Most appliances use AC electricity.

For instance, DELTA 2 has a huge 1800W AC output, meaning it can power over 90% of household appliances. What’s more, DELTA 2 can prevent overloading with built-in X-Boost Technology for devices of up to 2200W.


Different sizes impact portability, storage, and capacity. Ask yourself these questions:

  • Do I have a small/large home?
  • Are there frequent blackouts in my area?
  • Does large capacity matter, or does portability matter more?
  • Do I only require small devices to be charged?
  • Do I have large appliances that I/my family need to use during a blackout?

If portability is important to you, your household is small and you only need small devices like lights, a microwave, and phones charged during a power outage, a solar generator such as a DELTA 2 or River 2 Pro would be ideal for you

If, on the other hand, you have a large household, portability isn’t an issue, and you need heavy-duty appliances like a fridge, air-con, or heater to be powered up for extended periods, then a DELTA Pro that can be wheeled wherever needed would be your saving grace.

Cycle life

Our EcoFlow solar generators use either NCM or LFP (LiFePO4) battery chemistry. LFP is common for EcoFlow’s batteries and lasts up to 6 times longer than NCM. 

For example, the fine-tuned DELTA 2 has an LFP battery that will last 10 years of regular use. 

With NCM, batteries still last a long time. For instance, DELTA Max has an NCM battery with an estimated 800 cycles of full charge and discharge. 

Yet that doesn’t mean your solar generator will stop working. It simply means that it will charge to 80% capacity from when they were brand new. The benefit of NCM over LFP is weight. It’s lighter, making it a good choice if you favor portability.

Solar Input/Charging

Solar input determines how many solar panels you can use to charge your battery generator. To give some examples, DELTA 2 takes up to 500W solar charge. Whereas a DELTA Max takes 800W and DELTA Pro up to 1600W.

Bonus Benefits

The EcoFlow Ecosystem has multiple components that allow for expandable capacities, integration with other products such as the Power kits, the WAVE Portable AC unit, a suite of solar panels, smart algorithm control, and many more products to come in the future. All alongside the EcoFlow app for monitoring, control, and more.

The EcoFlow Smart Generator (Dual Fuel) is a fantastic solar generator add-on. You have the option to use fuel or gas to fully cover you in the event of an extreme blackout. The Smart Generator automatically charges your solar generator (either DELTA Max or DELTA Pro) when power levels drop. When compared to other brands, EcoFlow Smart Generator uses lower fuel emissions.
