Wrenches You can still AC couple Outback, they just eliminated tha option because of breaker issues but it can still be done using contactors all set to normally open and configured by DC Voltage. With Outback there is no real limit to battery capasity like you have with both the new SMA sunny boy storage and the Solar Edge, both high voltage and very limited capasity due to battery management abilities. The same way you do load sheding you can do power input reduction control. Jerry
