Whole home backup is less a product than a size. An EcoFlow whole home backup can be a single unit by the front door or a battery stack feeding selected circuits, and the right version depends on how long your outages run. Here are three blueprints with real prices, so you can see what each level costs and what it delivers.
How the Blueprints Were Built
All these plans utilize the same measuring tape to make sure that all figures can be compared properly. I decided to make calculations with the assumption of an exemplary essential electrical appliance load of 300 watts, that could consist of such devices as fridge, light bulbs, WiFi and fans, applying the advice from the DELTA website: multiplying capacity of the solar generator by 0.85 and dividing it into the load of electricity consumption. Replace my wattages with yours and the figures will automatically change in proportion. Price figures are based on the sale price at the DELTA products category page. The company’s homepage clearly states that the real number depends on certain factors.
- Apartment: DELTA 3 1000 Air, 960Wh, ₨135,000.
- Family home: DELTA 2 Max plus its Smart Extra Battery, 4,096Wh, ₨431,998.
- Extended outages: DELTA Pro plus its Smart Extra Battery, 7,696Wh, ₨839,998.
Blueprint One: The Apartment Setup
With 960Wh capacity and 500W of AC output or 800W with the X-Boost for running high-wattage appliances at reduced power, the DELTA 3 1000 Air switches over in 10 milliseconds for keeping the router and PC on during a power outage. This unit claims to run 99% of household essential appliances and offer up to 12 hours of household backup, which is reasonable for light loads. With 960Wh at 300W load, we get 816Wh or 2.7 hours of runtime.
This difference between 12 hours of runtime and 2.7 hours of runtime is the key takeaway of this blueprint: runtime varies with appliances. An affordable EcoFlow DELTA portable power station such as this is the most budget-friendly option for backup in the list, and it fits the bill for running the router, lights, fans, and charging phones in a flat. One thing to note here is that this listing does not feature any expansion options. In case you need one in the future, it might make sense to consider DELTA 3, which is expandable from 1kWh to 5kWh at ₨169,999.
Blueprint Two: The Family Home
Pair the DELTA 2 Max, which has 2,048Wh and 2,400W of AC output (4,800W surge), with its Smart Extra Battery at ₨164,999, and storage reaches 4,096Wh for ₨431,998. That gives about 3,480Wh usable, or 11.6 hours at 300W, enough to sleep through an outage and still have power in the morning. The 2,400W output, with X-Boost up to 3,100W, leaves room for an appliance beyond the essentials, and the app lets you monitor and control the unit from anywhere.
This is where an EcoFlow whole home backup starts to feel like a household system. There are enough hours to cover a night and enough output to run more than one appliance at a time. The extra battery weighs 19kg, so choose a spot where it can stay put.
Blueprint Three: Extended Outages and Solar
The output energy of the DELTA Pro is 3,600Wh and 3,600W in AC, and when using X-Boost, it expands to 4,500W. By adding its Smart Extra Battery which provides an extra 4,096Wh and costs ₨399,999, the total capacity of stored energy is 7,696Wh at the cost of ₨839,998, around 21.8 hours at 300W, or approximately a whole day. At this point, on the DELTA website, it suggests a transfer switch or a Smart Home Panel so that selected circuits are transferred automatically, and the solar panels charge the system without any fuel.
The DELTA Pro 3 at ₨799,999 is the alternative. It offers 4,096Wh and 4,000W continuous output with a 10ms switchover, and the series page names it for air conditioner loads. The balance differs: more output, less storage until you add a battery. Now compare the cost per hour of backup at the 300W yardstick:
- Apartment: about ₨49,600 per hour of backup.
- Family home: about ₨37,200 per hour.
- Extended outages: about ₨38,500 per hour.
The cheapest blueprint to buy is not the cheapest per hour. At this load, the family setup gives the most backup per rupee, though the ranking changes if your real load is much lighter or heavier.
Conclusion
An Whole home backup by EcoFlow is a sizing decision. Write down your essentials, divide the usable energy by their wattage, and pick the blueprint that clears your longest outage with margin. Every one of them starts with an EcoFlow DELTA portable power station, and the Clean Energy Solutions team can help you plan according to your needs.
FAQs
1. Can one of these setups power an entire house?
Not automatically. The homepage says coverage depends on configuration, connected appliances, output capacity and energy use. A single DELTA Pro runs essential circuits such as the fridge, lights, Wi-Fi, fans and medical devices.
2. Where does the 0.85 figure come from?
It is the rule of thumb on the DELTA series page for estimating usable runtime: multiply capacity in watt-hours by 0.85, then divide by the load in watts.
3. Do I need a transfer switch?
Only if you want selected home circuits powered automatically. The page pairs the DELTA Pro with a transfer switch or a Smart Home Panel for that purpose.
4. Can I start with Blueprint One and expand later?
The DELTA 3 1000 Air listing does not mention expansion. If growth is likely, look at the DELTA 3, which is expandable from 1kWh to 5kWh.
5. Can solar panels recharge these setups?
Yes. Every DELTA model has a solar input, and larger models accept more solar power. The DELTA Pro 3 is listed at up to 2,600W.
