Solar Generator for Garage and Workshop: What You Actually Need
Short answer: For a garage or workshop, surge wattage matters more than capacity. Power tools (circular saws, drills, compressors) need 2-5× their rated wattage to start. The EcoFlow Delta Pro (7,200W surge, $1,799) handles most workshop loads. For light workshop use (lights, small tools, battery charging), the EcoFlow Delta 2 Max (2,400W surge, $899) is sufficient.
Workshop Load Requirements
| Tool | Running watts | Startup surge | Suitable generator |
|---|---|---|---|
| LED shop lights ×4 | 80W | 80W | Any |
| Drill / impact driver | 400-600W | 800-1,200W | Delta 2 or larger |
| Circular saw | 1,200-1,800W | 2,400-3,600W | Delta Pro |
| Table saw | 1,500-2,000W | 3,000-4,500W | Delta Pro |
| Air compressor (small) | 1,000-1,500W | 3,000-4,500W | Delta Pro |
| Battery charger (tool) | 60-100W | 60-100W | Any |
| Angle grinder | 700-1,000W | 1,400-2,000W | Delta 2 Max or larger |
Honest Assessment
Solar generators work well for light workshop use — charging tool batteries, running LED lights, and powering smaller tools. For heavy workshop loads (table saws, air compressors, welders), a gas generator or shore power is more practical. The key limitation is not capacity (Wh) but sustained continuous output — the Delta Pro’s 3,600W continuous is real, but a table saw running for 2 hours will deplete even 3,600 Wh quickly.
