The short answer
Growatt INFINITY 1500 costs $1900 less. Whether that gap is worth closing depends on what you need to run.
- Mango Power E holds 134% more energy (3533Wh vs 1512Wh), so it runs the same load proportionally longer.
- Mango Power E has 3000W more surge headroom (6000W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Growatt INFINITY 1500 is 35.6 lb lighter (37.5 lb vs 73.1 lb).
Growatt INFINITY 1500
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
Mango Power E
A polished 3.5kWh home unit with a standout 10-year warranty. The catch is a relatively low 660W solar input for the capacity.
Best for: Home-backup buyers who want a long warranty and lots of capacity.
Where it falls short:
- 660W solar input is low for 3.5kWh
- 73.1 lb
