The short answer
Growatt VITA 550 costs $2600 less. Whether that gap is worth closing depends on what you need to run.
- Mango Power E holds 557% more energy (3533Wh vs 538Wh), so it runs the same load proportionally longer.
- Mango Power E has 4800W more surge headroom (6000W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Growatt VITA 550 is 55.5 lb lighter (17.6 lb vs 73.1 lb).
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
Growatt VITA 550
A tidy half-kWh unit with fast charging and a 1,200W surge that lets it start small appliances a 600W rating wouldn't suggest.
Best for: Campers who want fast charging and a bit of surge headroom at half a kWh.
Where it falls short:
- 538Wh is weekend-scale
- 3-year warranty
