    Answer This Question

    Thank you for contacting EcoFlow! Yes! The DELTA 3 Classic can power your connected devices while charging through a solar panel.

      This works with a 1500-watt heater 115 volts
      ByNov 9, 2026
      1 Answer | 
      Answer This Question

      Thank you for contacting EcoFlow! Yes, the DELTA 3 Classic can power a 1,500W heater rated at 115V, as its AC output is rated at 1,800W. Please keep in mind that the heater will draw a significant amount of power, so the battery runtime will be limited. Actual runtime will depend on the unit's available battery capacity and the heater's continuous power consumption.

          Can I hook up two 220W solar panels in series to speed up recharging time. Also is there an extension cord when connecting the generator to the solar panels so that I can leave the generator inside the house when recharging?
          ByNov 9, 2026
          1 Answer | 
          Answer This Question

          Thank you for contacting EcoFlow! Yes, you can connect two 220W solar panels in series to increase the charging input, provided their combined voltage and current remain within the DELTA 3 Ultra's solar input specifications of 11V–60V, 18A maximum, and 800W maximum. For your second question, EcoFlow offers solar extension cables that allow you to increase the distance between the solar panels and your power station. This can help you position the panels outdoors while keeping the DELTA 3 Ultra inside your home.

              When this unit's battery is full will it power items, such as an 18v 4Ah battery charger, directly from the solar panel assuming the draw is less than the solar input?

                I have this generator to support my inverter refrigerator and for protection since I have a lot of power outages, until now, it works incredible

                It's wonderful to hear that your DELTA 3 Classic has been providing reliable backup power for your inverter refrigerator, especially with frequent power outages in your area. Having dependable power when you need it most makes all the difference! We're glad your EcoFlow unit has been performing incredibly well. Thank you for sharing your experience! ecoflow
                The product is great, but we need to move up to a higher spec. The fast recharging time is very helpful. I sent it off to Cuba to help out the family. They are over the moon with it. We've had it a month and so far no complaints.

                Awesome portable / backup power! It charges super fast from the wall, has a reasonable charge time from solar, and was able to power multiple freezers at the same time, for a long time. I'm very happy with this purchase

                Persistent Battery SOC Gauge Problems
                I purchased the EcoFlow DELTA 3 Classic for UPS backup power and spent considerable time testing its performance. Unfortunately, I encountered persistent problems with the battery state-of-charge (SOC) gauge. During discharge, the displayed percentage initially decreased normally, then began dropping much faster before becoming stuck at a low percentage for extended periods. On one test, it remained at 1% for approximately two hours while the unit continued supplying power. On another, it remained at 8% for over an hour. I experienced essentially the same behavior with two DELTA 3 Classic units. I also have a DELTA 3 Max and it does not exhibit this problem. I performed multiple discharge/recharge cycles and performed the recommended SOC calibration but the issue persisted. The battery may still have usable capacity, but an unreliable SOC gauge makes it difficult to determine how much runtime remains and to depend on configured discharge limits. This is particularly concerning when using the unit as a UPS or for backup power during an outage. I contacted EcoFlow support and provided a detailed written description of the problem. Further troubleshooting required photographs and videos, and I ultimately decided to return the unit rather than continue testing. Based on my experience, I cannot recommend the DELTA 3 Classic for applications where dependable battery-state reporting is important. My experience is specific to the two units I tested, but prospective buyers should be aware of this issue.
