Easy to install. I used it to change the connection from my solar panels to either my inverter's inputs or outputs, so I used it backwards: the solar panels connect to this miniATS' output and this miniATS' utility input is connected to the inverter's utility input and this miniATS' generator input is connected to my inverter's output. So depending on utility availability the solar panels output are switched to either help the loads OR help the loads and charge the battery through the bidirectional inverter output. Excellent value for the money.
