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
Growatt VITA 550 costs $1000 less. Whether that gap is worth closing depends on what you need to run.
- Jackery Explorer 2000 v2 holds 280% more energy (2042Wh vs 538Wh), so it runs the same load proportionally longer.
- Jackery Explorer 2000 v2 has 3200W more surge headroom (4400W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Growatt VITA 550 is 21.9 lb lighter (17.6 lb vs 39.5 lb).
- Jackery Explorer 2000 v2 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Jackery Explorer 2000 v2
The portability champion of the 2kWh class. At 39.5 lb it's over 20 lb lighter than the Bluetti AC200L with similar capacity.
Best for: RV and van owners who need 2kWh but have to lift it in and out.
Where it falls short:
- 400W solar input is low for this capacity — slow off-grid recharge
- Not expandable
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
