Hi Christopher If it is a newer radian then it has an ac coupling mode.
When the batteries start to reach the charge set point, the inverter starts pushing the hz up snd up. Once it gets to 64, all new GT inverters shut off, including enphase. Voltage drops, hz drops, 5 minute delay, rinse and repeat. It’s a a great feature for infrequent control needs. This only comes into play when the grid is down and the batteries are full. I hope this helps.
