## Questions & Answers

**Q: How much extra cost to get the 25kWh capacity?**
A: The total price for a 25kWh system if you have nothing to start with would be $15,598.

**Q: How long could this power my 1200 watt (not sure how to figure this out since a frige isnt always running)refrigerator?**
A: kW is like speed and kWh is like distance. If you travel at 36 mph for 1hr, you go 36 miles. If you only go 18mph, it takes 2 hrs.

Similar here… IF (spoiler-it does not) your fridge ran at a “speed” of 1200W continuously, it would take 3600 Wh (3.6 kWh) to run for 3 hrs. If it ran 1200W 25% of the time and 300W 75%, it would use 525 Wh each hour, and would use 3600 Wh over 6:50+/-.

So does the unit *provide* 3600Wh per charge to its load? Or, as another pointed out, do the losses from converting battery energy to electric energy reduce the useful energy output?

Also, the percent of time the compressor runs determines whether it’s 25%, or 50%, or ??% at 1200W, and what it uses the other times is not on any ratings-you’d have to test your fridge to find out.

So if the USEFUL output is 70% of rating (2,520 Wh), and your fridge ran full-tilt the whole time, you’d get about 2hrs. If useful output is the full 3600 Wh, then 3 hrs.

So the precise answer is it will run at exactly between 2 and (insert your guess here) hours.

**Q: Does the app and unit still require an internet connection to function together?**
A: In order to control ecoflow delta pro via mobile app a wifi or cell connection is required, as they communicate via ecoflow cloud. Ecoflow delta pro can be controlled from anywhere as long as it is linked to cloud and there is an internet connection.

**Q: Can this be used as a ups system ? can i run my appliances off of it while it stays plugged in?**
A: The product supports EPS (Emergency Standby) function. After the power is off, the product can automatically switch to the power supply mode of the battery within 30ms. Hope this help you!

## Customer Reviews

### ⭐⭐⭐⭐⭐ Best, user friendly, exceptional addition to my RV life
*by V***D on April 2, 2023*

Even though I am on ground floor when it comes to the upgrades to my RV life, this investment was a good one to start my solar power journey. I purchased this because I ddnt want to modify the RV, I loved the idea of being able to trade in or purchase a bigger/better RV and taking my solar power equipment with me, so this fits my agenda.I intend to add solar panels to my (they'll be here Saturday) equipment, so stand by for the updates. At the moment I utilize my 2200 W gas generator to recharge it but because of the multiple charging options, sometimes I charge it in the garage outlet.The noise level is at a minimum because it just consists of fans blowing, no loud noises. The retractable handle makes the mobility much easier but definitely not easy.

### ⭐⭐⭐⭐⭐ EF ECOFLOW 240V/7200Wh The Perfect Plug & Play Generator For Any Home
*by G***E on December 12, 2023*

The ECOFLOW DELTA Pro with Double Voltage Hub (240V/7200Wh) is a great investment for worldwide usage. With the proper installation for home use during power outages, it is a definite advantage with the plug and play capabilities. This system is upgradable in terms of battery capacity which can also be charged with solar panels and or other sources such as home AC outlets, vehicle, and EV charging stations. For camping adventures, just take one of the Delta Pros along with a couple of solar panels and you are all set for comfort out in the wilderness. I would definitely recommend this setup to all customers considering a back source of power during emergencies.

### ⭐ poor quality poor customer service
*by L***E on August 4, 2023*

DO NOT BUY THIS PRODUCT. Eco Flo is not capable of sending a valid shipping label for a return.I have been routed to the same person who is not able to replace the DAMAGED ON ARRIVAL product.I will remove this review when I have a product that does not have a broken solar input. This product isunnecessary extra work disassembly and or the stealing of consumers time.
