Recommended generator
14–22kW home standby generator
- Running watts: 4,200W typical (range 3,500W–5,000W)
- Peak (starting) requirement: 11,600W (starting range 9,500W–13,500W)
- With 25% headroom: 14,500W minimum rating
⚡ 240V required — this load needs a 240V-capable generator (e.g. an L14-30R outlet). Standard 120V-only inverters cannot run it at any wattage.
