✅ Specs verified against the manufacturer's official listing — source · Last checked
Our verdict
A large expandable unit that undercuts the EcoFlow Delta Pro 3 on price while matching its 4,000W output — the trade is a less established support network.
Best for: Whole-home backup buyers prioritising price per watt over brand.
What we like
- 4,000W output at a lower price than the majors
- Expandable
- 2,000W solar input
Where it falls short
- 106 lb
- Brand support and resale trail the big names
