Hi Bill In the past I’ve had similar issues with generators/inverters. Usually a relay on the output power wires that opens( disconnects) when the stop signal is sent works as the frequency doesn’t slowly go down, it drops to 0 instantly. I don’t know if it will fix your issue.
Seems like solark needs to greatly improve their firmware.
