<span style="font-size:small;text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline" class="">Larry.....Outback Radian would work fine but you would need 2 of the 8kW inverters for your ~11kW GT inverter. Outback recommends a maximum 75% loading ratio when AC coupling. We have used a simple solid state relay controlled by the Aux Out of the Radian to turn off one leg of the SolarEdge or any other GT inverter essentially shutting off the GT inverter when a desired battery voltage is reached. </span><div style="font-size:small;text-decoration-style:initial;text-decoration-color:initial" class="">As an aside, in earlier days when lead acid batteries where the main battery technology I didn't like this set up because it didn't allow multistage charging of the batteries leading to batteries only reaching approximately 80% SOC (bad for batteries) because there was no ability to taper charge (aside from frequency shift compatible inverters). But nowadays with Lithium batteries, which don't require multistage charging becoming more common this method of AC coupling is pretty attractive because the batteries don't care if they only reach a partial state of charge....Even though you can charge them more than 80% before kicking off the GT inverter. We have used this method successfully in addition to having DC coupling present in the same system as well.</div><div style="font-size:small;text-decoration-style:initial;text-decoration-color:initial" class="">Let me know if you need a diagram.</div>
