380V pump running on solar power as well as 220V generator.

We have this little 0,55kW 380V pump that is running on solar power through a Variable Speed Drive (VSD). (Pump duty = 2000 litres per hour x 60 metre head.) On a rainy day our customer just plug in his 220V generator and pump away. The system has been running for three months now and our client is smiling.
