Anker SOLIX F3800 vs Pecron E3600LFP
Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
Pecron E3600LFP costs $2300 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F3800 holds 28% more energy (3840Wh vs 3000Wh), so it runs the same load proportionally longer.
- Anker SOLIX F3800 has 2000W more surge headroom (9000W vs 7000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Pecron E3600LFP is 55.3 lb lighter (77 lb vs 132.3 lb).
- Anker SOLIX F3800 is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
The Anker SOLIX F3800 is poor value on paper: 0.96 Wh per dollar versus 1.77 for the Pecron E3600LFP. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
This is where portable power stops being portable and starts replacing a standby generator. The 240V split-phase output is the headline feature.
Best for: Whole-home backup where you need 240V loads and can't run a gas generator.
Where it falls short:
- 132 lb — this is a wheeled appliance, not something you carry
- $3,999 puts it against real standby generators
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
