Thanks Sorry I did not give you enough info.
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 nother 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.?
Hope fully I gave you more info to work with this time , I am new at asking questions on the internet Thanks for helping.
