In my installation, I have a Multiplus II, a battery bank, an MPPT controller, a SmartShunt, and a Venus OS.
My problem is that I have it configured so it doesn’t inject power into the grid, but sometimes it does, or so the statistics show me through the VRM portal.
I understand that increasing the grid setpoint setting could solve the problem, since I initially had it at 0W and the injection was higher.
I assume it’s like Alex Pescaru says and there’s no solution. Since the injection is minimal, it wouldn’t cause me any problems with my electric service provider.
The controller can only react to a deviation if it is there. Therefore deviations will always occur briefly and will add up to a certain amount of injection.
