Grid tie function on MPPT 150/70 not functioning did not change setting it just stoped grid feed something is telling the MPPT 150/70 to lower carging

I have an grid tie solar system. 1 x inverter that is 100 present grid tie(sun plug module)

then I got solar charge controller 150/70 connected to 4 x 200 ah AGM gel batteries that is connected to my 48/5000/70 victron multi. This system is also set up to do grid feed when batteries is full. On this stage the sunplug is working fine but for one reason or a other the victron system stopped grid feed during the day. In the morning it kick of with a good grid feed at about 9am it start to scale down to 53 watt (normally giving about 3000 watt grid feed. then at 4 pm the system suddenly pick up speed and grid feed again.

The system was running good for years until this problem stated about a week ago.

I did not change any settings in that period it is an system self inflicted fault and I do not know how to fix it or where to start looking for the problem.?

It can be that there is an setting that got corrupted in my multipkus 48/5000/70 ? I am just guessing.

Hope fully I gave you more info to work with this time , I am new at asking questions on the internet Thanks for helping.

I have got an solution to my problem if there is any one with the same problem. You have to switch on the DVCC function on your multiplus but it has to have V2.22 ve.bus firmware 422 or later and ve.direct must be V1.29. also remember that ve.can solar chargers are not supported.
