Key Performance Features

• High Output & Surge: Delivers 2000 watts of continuous AC power with a high surge capability of up to 50 amps (6000 watts for 5 seconds), allowing it to start demanding loads like microwaves or coffee makers.

• Efficient 3-Stage Charging: The built-in 100A DC battery charger uses a multi-stage process (Bulk, Acceptance, Float) to rapidly recharge deep-cycle batteries while protecting their long-term health.

• Filtered Modified Sine Wave: Provides a clean AC output that is compatible with most household appliances, office equipment, and onboard electronics.

• Automatic Transfer Switch: Features an integrated 30A transfer relay that instantly switches between inverter power and incoming shore/generator power when available.

• Power Sharing: Intelligently reduces the battery charge rate when large AC loads are active to prevent nuisance tripping of your shore power breaker.
