Grid tie inverter for net metering

On Tuesday I played with a so-called 'grid-tie inverter' that supplies electricity to the national grid from a wind generator or from solar panels. Balancing one's own generated electricity against that supplied from the grid is called 'net metering'. This is certainly a good way to ensure that all one's own generated electricity is used to good effect. The only snag seems to be that the UK (and some European) regulations insist that the inverter is disconnected if mains power fails. This means that grid tie eliminates the facility for back up in case of power fail. Renewable energy customers in the UK, etc. will have to choose between these two options. The new web site from Ampair (coming soon) will offer both wind and solar solutions for home renewable energy.
