The echo-charger is great for mixed chemistry battery setups such as your planning. AGM for start and Flooded for house. Each type of battery requires different charge profiles. With the same chemisty the ACR allows for a higher current charge to switched bank. The echos are limited to 20Amps...IIRC. I too am eager to hear why Rich is partial to the echo.
