The Go Power! Advanced Sine Wave Inverter with Transfer Switch transitions between shore power and battery power. When AC power is available, it passes through excess power to run appliances. When AC power is disconnected, the built-in transfer switch activates the inverter, converting DC battery power into clean, reliable AC electricity. PowerTrak™ compatible.








Actual product may not be exactly as shown.
The Advanced Sine Wave Inverter (ASW-1200-12-TS) is built for RV owners who already have a battery charger or solar charging system in place and need a reliable inverter with automatic transfer capability. When shore power is available, it passes AC power through to your loads. When shore power is disconnected, it automatically switches to inverter mode and draws from your battery bank. No manual switching required. At 1200 watts of pure sine wave output, it handles sensitive electronics, small appliances, and DC loads cleanly and efficiently. The built-in 30-amp transfer switch eliminates the need for a separate transfer switch component. PowerTrak™ and RV-C compatible, lithium-ready, and hardwire ready. We recommend installation by a certified RV technician or licensed electrician. Key Benefits| SPECIFICATIONS | ASW-1200-12-TS |
