What they say
EcoFlow DELTA Pro Ultra X
- DELTA Pro Ultra X owners in r/Ecoflow_community report a new three-battery unit that shut the house down twice with error 2558 at about 2 kW (February 2026), and a four-battery owner whose single unit could not start a new 4-ton air conditioner, which support said needs three inverters (March 2026).
- A 120 kWh owner needed soft starters before Smart Home Panel 3 stopped falling back to grid on each HVAC start but projects a five-year payback, and another called it a best purchase (May 2026).
Dabbsson TURBO 12000
- No Reddit thread discusses the TURBO 12000; in r/SolarDIY an owner's DBS2300 began throwing overload and error codes with inverter functions failing after two weeks, and he graded Dabbsson's customer service an F (November 2023).

What they say
EcoFlow DELTA Pro Ultra X
- TheSolarLab, which earns affiliate commission and offers a discount code, measured about 36 W of idle draw and reached 10 kW of solar and 12 kW of AC charging, but found compressor starts inconsistent, load balancing that trips at about 6.5 kW on one leg, and UPS mode adding load on top of charging.
- ZDNet, which earns affiliate commission, ran a 3,000 sq ft home including air conditioning through an outage with a switchover under 20 ms (April 2026).
