Ring Main Unit (RMU) is a switchgear device used in secondary distribution systems, i.e., between the distribution substation and the end consumer to ensure continuous power supply and isolate the faulty section from the network. The main purpose of using a ring main unit is to provide an uninterrupted power supply to consumers even in fault conditions.
For obvious safety reasons my residential PV system disconnects from the grid if it notes the grid is down. The thing is it also shuts itself off so that during a grid blackout rather than providing me power but detaching from the grid the inverter disconnects itself from both the grid and the panels leaving me without power.
One way to manage load would be to charge batteries, as explained by Eric Friend above, but the batteries would be costly, defeating the point of trying to get value out of your existing expensive system. Trying to balance household load with available solar power would be complicated.
Aside from being picky about a clean, 60 Hz sine wave, I would expect the inverter to shut down if its output voltage dropped too low (short circuit - grid power outage) or went too high (main breaker open). So without the grid connected, the load would have to be managed carefully to keep the inverter on.
