Best for Basic Home Backup: EcoFlow DELTA 2 Max + 220W Solar Panel
This model is the perfect choice if you are looking for a basic home backup product to run your essential appliances during an outage. Without fossil fuels, they can be brought indoors since there is no need to worry about lethal carbon monoxide poisoning. Its 2048Wh capacity and 3400W surge output means it will run virtually any household appliance.
You can keep your refrigerator running, run lights, recharge your electronic devices, and watch the telly at night. Even if you need to run a heater or an air conditioner, it can run those, too.
The nice thing about this model is that while it has a lot of capacity, it does not have so much that it makes it cumbersome to move around. You can move it from room to room or pack it in your shop or car for a road trip. The 220W bifacial photovoltaic panel is perfect for efficient recharging since it collects light from both sides of the panel.
It also makes an excellent generator for boats. It’s an especially great generator for fishing trips where you can run a GPS, fishfinder, lights, and a heater to stay warm on chilly mornings. It’s rugged and durable, and both the panel and the generator are IP68-rated as waterproof according to the International Electrotechnical Commission standards.

What Makes a Good Home Solar Product?
What makes a good home photovoltaic product depends on how you need to use it. If you just want to supplement your daily energy supply, photovoltaic panels alone might be enough, but you won’t be able to use them at night.
If you want to live off-grid, avoid those peak electricity hours when your electrical company charges you the most, or if you want energy during electrical outages, you need photovoltaic batteries to go with those panels so you can store your power.
Here are some additional factors to consider.
Capacity
Capacity is easily the most important factor for home use. How much capacity you need depends on how much energy you use and how you want to use it. If you want a backup solution for essential appliances, a whole home backup, or a complete off-grid solution, these all require different capacities.
Durability
Durability is also essential. Your panels and power station should be well-built, sturdy, and have good dust and waterproof ratings for use indoors or outdoors.
Efficiency
Not all photovoltaic panels are created equal. Most have conversion efficiencies between 16-22%. With all the affordable, highly efficient EcoFlow photovoltaic panels generating 22% or more, you don’t want to buy anything with a lower efficiency rating because you would need more panels to create the same amount of electricity.
Warranties
People often overlook warranties when shopping for a bargain, but buying cheap products from an obscure manufacturer with limited warranties means they don’t stand by their products. Your system should have a 5-year warranty with no restrictions.
Final Thoughts
When it comes to solar solutions for UK homes, EcoFlow delivers exceptional performance, durability, and flexibility. Whether you’re looking for a reliable backup power source, an affordable whole-home backup solution, or maximising your power generation and output with the EcoFlow DELTA Pro 3, there’s a generator to meet every need.
Invest in clean energy, reduce reliance on the grid, and ensure you’re always powered up no matter what life brings.
