Hello,
There are massive numbers of PFC control chips available off the shelf. Why are there not any IC’s available for low power (<300W) H Bridge inverters for putting power back into the mains?
All the controllers used for H-bridge inverters seem to be high-end microcontrollers.
 

Because there is a lot to consider when poking power into the mains - start up, synch, soft start, controlled current, peak and average/rms current limiting, measuring of injected current ( & V & power) keeping the HVDC bus in bounds, injecting <5mA DC into the mains ... disconnecting when the mains goes away...
