How amazing AC-coupling works in Deye/Sunsynk inverter - limiter works using frequency, perfecto!

Guys, due to my situation of living in Ukraine, and having constant grid power supply issues, due to the freaks that attacked my country - I am able to show you a lot of tests in real life. And those are the tests that even the provider/manufacturer of this inverter is never ever showing you.

So here is the thing.
Deye 10kW 3-phase hybrid inverter is AC-coupled through the GEN-port (which works in MicroInv Input mode) with Huawei 3-phase grid-tie inverter of total 22kW power production capability.

Deye itself has 12.5 kW of panels on it, Huawei has 30.3 kW panels on it.

How exactly does it work - it limits the intake from the AC-coupled device using "frequency brakes", upping the frequency to 50.2, 50.3, 50.4 or 50.5 it applies slow braking for the coupled device. and once it reaches the battery full status - it just cliks, and relay turns the MI input off. It will get back on once there is either grid back, or if the battery drains down to 95% in an off-grid mode.
