Review on 1200W Pure Sine Wave Inverter With AC Charger, DC 12V To AC 120V Output - Off Grid Inverter For Lithium, Sealed, AGM, Gel, And Flooded Batteries By Ampinvt by Lequon Kirkpatrick

Arrived in great condition and packaged well. Instructions booklet is included. As another reviewer indicated , this is one of the few inverter and charger with ATS on the market. I like the wall mounted industrial design and used this in the garage as part of an non grid tied system powering a large freezer. After setting up this inverter and testing its ATS capabilities, I was quite impressed. This unit switches power quickly when AC input is dropped, I tested with a light, fan, heater, and large freezer when pulling AC it transferred over with no issues. I decided to also purchase their 40A MPPT Solar Charge Controller which works great with this unit. Thank you Ampinvt !
