How long can it power a 6000 btu air conditioner
ByAug 12, 2026
1 Answer | 
Answer This Question

Thank you for your inquiry. The EcoFlow DELTA Pro Solar Generator features a 3,600Wh battery capacity and 3,600W AC output (7,200W surge), making it capable of powering most 6,000 BTU portable air conditioners, provided the unit's startup and running power requirements are within the DELTA Pro's output capacity. A typical 6,000 BTU portable air conditioner consumes approximately 600–750W while running. Based on this, the DELTA Pro can provide an estimated runtime of approximately 4.5–5 hours under typical operating conditions. Actual runtime may vary depending on the air conditioner's power consumption, compressor cycling, ambient temperature, and other operating conditions. If your air conditioner is hardwired to your home's electrical panel (circuit breaker) rather than being a portable plug-in unit, it cannot be powered by simply plugging it into the DELTA Pro. In this case, you would need a transfer switch or a subpanel (such as the EcoFlow Smart Home Panel) to safely connect the DELTA Pro to your home's electrical system. If you can provide the brand and model of your air conditioner, we'd be happy to verify compatibility and provide a more accurate runtime estimate.

      how many solar panels can be connected to the system at the same time?
      ByJul 21, 2026
      1 Answer | 
      Answer This Question

      Thank you for your question. The EcoFlow DELTA Pro Solar Generator with a 400W Solar Panel supports a maximum solar input of 1,600W. This means you can connect up to four (4) EcoFlow 400W Solar Panels simultaneously, provided they are connected in a configuration that stays within the DELTA Pro's supported solar input specifications (11–150V DC, 15A max, 1,600W max). When adding multiple panels, please ensure the total voltage and current remain within these limits for safe and optimal charging. If you have any other questions about solar panel configurations or compatibility, please let us know. We're happy to help.

        How long the battery last for using a refrigerator
        ByJun 25, 2026
        1 Answer | 
        Answer This Question

        Thank you for your inquiry. The runtime of the DELTA 2 will depend on the power consumption of your refrigerator. The DELTA 2 has a battery capacity of approximately 1024Wh, so the lower the refrigerator's power draw, the longer it can run. For example: If your refrigerator consumes 100W, the DELTA 2 could power it for approximately 8–10 hours. If your refrigerator consumes 200W, the runtime would be approximately 4–5 hours. If your refrigerator consumes 300W, the runtime would be approximately 3 hours. Please note that refrigerators cycle on and off throughout the day, so actual runtime may be longer than these estimates depending on the model, ambient temperature, and usage conditions. If you provide the make and model of your refrigerator or its rated wattage, we'd be happy to provide a more accurate runtime estimate.

          In order to run my refrigerator, do I connect it to power box or to the frig directly?
          ByMay 26, 2026
          1 Answer | 
          Answer This Question

          Thank you for your inquiry.​ To run your refrigerator using the DELTA Pro Solar Generator, you would typically plug the refrigerator directly into one of the AC output outlets on the DELTA Pro power station.​ If you are using a home transfer switch, power box, or backup power setup, the connection method may differ depending on the installation. For standard use, however, the refrigerator connects directly to the DELTA Pro unit.​ Please also verify your refrigerator’s power requirements to ensure compatibility with the DELTA Pro output capacity.

            Will it automatically convert if the power goes out?
            ByMay 16, 2026
            1 Answer | 
            Answer This Question

            Thanks for your inquiry,Yes. According to EcoFlow’s official DELTA Pro manual and website, the unit has an EPS (Emergency Power Supply) function. When it is connected to grid power and your appliances are plugged into the AC output, it will automatically switch to battery power in about 30ms if a power outage occurs.

              This is a product one wouldn't necessarily think of purchasing from The Home Depot, but I'm so glad I did. The product is exactly the same as elsewhere, but I received a better price and The Home Depot's reputation of being there during and after the sale.
              by
              I purchased the EcoFlow Delta 2 solar generator and 220W solar panel on sale at Home Depot. Then I added a Delta 2 smart extra battery to complete the system. This gear is very well made, high quality and easy to use with the highly functional app. Looks perfect to upgrade your camping routine (lightweight and solar panels fold up); I plan to use it at home to power up important appliances (fridge, internet modem, etc.) in case of wildfire power shutdowns.

              Almost great!
              Deducting one star due to utterly frustrating and worthless internal WiFi - read on. Going on six months ownership, we have used this extensively in the hold of our travel trailer for our desert camping. Plus side: I paid $2,150 here at Home Depot for the Delta Pro with 400w solar panels. Would’ve cost at least $1K more for the equivalent rooftop solar and 300ah battle born lithium batteries with an inverter. No rooftop install, no holes on the trailer, and, I just bought a fifth wheel and easily transferred the unit to the new trailer. Although it has a 30a outlet, I’ve only used it once as a test. I run an outdoor extension cord to the 30a or now 50a trailer shore power port with a 110 dog bone and the trailer has full 110v and DC power from the Delta Pro. I turn off the small trailer house battery from the battery disconnect to keep the Delta Pro from constantly trying to top off the house battery. I’ve seen the 800w solar panels produce nearly the max wattage on a cold sunny winter day. Pretty good. Cons: The portable solar panel design is cute but a bit of a pain to deploy and especially drag around to follow the sun. Ingenious design but execution needs work. The one thing that is totally frustrating and mostly worthless is the internal WiFi. The WiFi works fine when you have internet access at ho e of office to connect to. It allows you to see the amount of t of power inbound to recharge the box and more importantly the wattage being used, amount of time remaining before exhaustion, and recharge time if you’re topping off. HOWEVER, when not connected to home internet, you have to constantly run out to the unit and press the ioT button to reset the internal wifi. A total pain as mi e is in the belly of the trailer. Without the internal wifi you’re left to only knowing percent of charge, which is ok but the more info the better. Would I buy again, yes, it works well. Just don’t expect a comprehensive manual or tech support. You’re left to fend for yourself in FB user forums. There’s also quite a few comments about bricked units attempting to update firmware. I have not had this issue. Good luck!

                I haven't been able to use the power station. I did charge the units with the 400w panels. With the units at 25% they took only 3.5 hours to charge in direct sun light, At times I was getting 400w plus out of the panels. While the panels are a little flimsy, I have since takes a piece of wood 12" long and used two clamps at each panei divide (3) to stiffen them up.

                Poor customer experience
                Hello Home depot I been experiencing really bad experience with online purchasing. After purchasing 2 solar panels with butteries on March 3rd. Order #WG56527272 spending 3176.87$ I received only batteries and was missing 2 of the 400 watts solar panels. Shipping is as promised for March 7 th. Today is march 13 and I called 3 different times after not receiving my solar panels with the rest my orders. I called home depot online store and was promised that my panels are going to be delivered by March 11. I did not receive my solar panels. So I called 2 time and spoke with Tiaqua on March 11 and she said if I don’t receive my item by March 13 to call back so home depot can reorder my missing panels. I called for the 3rd time and was on hold with the rep David who for over a hour. David was very helpful and guaranteed me a discount for inconvenience and to get my order shipped with priority shipping. David gave me a Case number 3538872 for my missing solar panels. I’m cutting waiting on someone to call me to confirm that my panels are on the way for delivery. I’m very disappointed how home depot did not complete shipping my order when it was promised. I hope home depot management gets this case prioritised and gets my missing solar panels shipped asap.
