Growatt INFINITY 1500 vs Pecron E1000LFP
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 E1000LFP costs $500 less. Whether that gap is worth closing depends on what you need to run.
- Growatt INFINITY 1500 holds 48% more energy (1512Wh vs 1024Wh), so it runs the same load proportionally longer.
- Pecron E1000LFP is 13.2 lb lighter (24.3 lb vs 37.5 lb).
- Pecron E1000LFP is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
A capable mid-size that flies under the radar. Solid 2,000W output and fast charging, let down mainly by a shorter warranty than the big brands.
Best for: Value hunters who want 1.5kWh and don't need the longest warranty.
Where it falls short:
- 3,000W surge is modest for the output
- 3-year warranty vs 5 from the majors
An expandable 1kWh at a budget price — unusual to find expansion this cheap, though the 1,000W output caps heavier loads.
Best for: Budget buyers who want a 1kWh they can later expand.
Where it falls short:
- 400W solar input is modest for the capacity
- Smaller brand support
