Show expert analysisTechnical: **Running load:** 4500 W. **Surge:** 4500 W. **Voltage:** 240V split-phase required. Resistive heating element draws steady current without inrush spike. Field note: Ensure power station maintains 240V regulation under sustained 4500 W load. Voltage sag below 220V may trigger thermal cutoff. Can I power this water heater with a portable power station? Only if your power source provides 240V split-phase output and can supply 4500W continuous and 4500W surge. | |||||

Show expert analysisTechnical: **Running load:** 5,500 W. **Surge:** 5,500 W. **Voltage:** 240V. Requires a power station with split-phase 240V output and sustained 5,500 W capacity. Field note: Confirm your power station supports continuous 5,500 W output without thermal derating. Verify 240V split-phase before connection. Can I run this water heater on a portable power station? Only if your power source provides 240V split-phase output and can supply 5500W continuous and 5500W surge. Verify voltage and sustained wattage capacity before attempting operation. | |||||

Show expert analysisTechnical: **Running load:** 4500 W continuous at 240V. **Surge:** 4500 W (resistive heating element, no inrush spike). Only compatible if your power station supplies true 240V split-phase output and sustained 4500 W capacity. Field note: Verify your power station explicitly supports 240V loads before connecting. Most portable units output 120V only and cannot safely power this water heater. Can I run this water heater on a portable power station? Only if your power source provides 240V split-phase output and can supply 4500W continuous and 4500W surge. Most consumer units do not. | |||||

With 24,000W surge capacity, this system can handle typical compressor startup events found in central air conditioners, well pumps, and refrigeration equipment. The 12,000W continuous rating supports sustained high-load operation across multiple circuits. At 6,144Wh usable capacity, runtime depends on connected load, but this configuration can support whole-home essentials during extended outages.
This unit uses LFP chemistry, a formulation widely recognized for thermal stability in residential backup applications. The manufacturer provides operational guidelines in their documentation, and users should follow all installation and grounding instructions.

Yes. The EcoFlow Delta Pro Ultra X provides 12000W running / 24000W surge. The Electric Water Heater (50 Gal) needs 6051W / 6051W (including 10% buffer). That leaves 5949W of running headroom and 17949W of surge margin.
Approximately 0.8 hours, based on the Electric Water Heater (50 Gal)'s 5500W draw and the Delta Pro Ultra X's 6144Wh capacity (70% usable after real-world losses).
With 1940W allocated to the Electric Water Heater (50 Gal), the Delta Pro Ultra X still has ~2160W of margin. These devices could run simultaneously:
Power Tip: To get the most out of your Delta Pro Ultra X, keep it in a well-ventilated area. Extreme temperatures can slightly reduce the efficiency of the LFP/NMC cells.
