The short answer
Pecron E3600LFP costs $1500 less. Whether that gap is worth closing depends on what you need to run.

- EcoFlow DELTA Pro has 200W more surge headroom (7200W vs 7000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Pecron E3600LFP is 22.0 lb lighter (77 lb vs 99 lb).
EcoFlow DELTA Pro
The previous-generation flagship, now mostly worth buying on discount. The Pro 3 beats it on nearly every axis.
Best for: Bargain hunters who find it steeply discounted against the Pro 3.
Where it falls short:
- 99 lb and 165-minute recharge — both beaten by the Pro 3
- Aging platform; expect it to be phased out
Pecron E3600LFP
A 3kWh unit with 3,600W output and 2,500W solar input at a price well below the flagship majors — strong specs, smaller brand.
Best for: Whole-home backup buyers chasing capacity and solar input per dollar.
Where it falls short:
- 77 lb
- Brand support and resale trail the majors
