Solar Panels Providing Sufficient Power To Cover Higher Loads But Always Providing Less Than Load With Low Loads.
Solar power covers higher loads but is always under supplying low loads.
The panels have no problem providing sufficient power to charge the batteries, but directly after SOC has reached 100% the load drops to 200W and the panels only provide 145W instead of providing slightly more than the load. This occurs only on low loads throughout the day with full sun. When the load increases again to +- 2000W the panels then provide slightly more than the load, as expected.

I suspect there is also some measurement error in here. The current & power figures on each stream are generated from micro CT coils or similar. It may well be that the error is absolute, creating an offset as opposed to being relative to amount of current. If so, the total current power may not be the sum of the parts & this will be exaggerated at low values. Using a calibrated meter at the inverter is the only way to be sure.
