The ENER·G micro series have the lightest and most compact generators available built in. Compared to other generators these give a higher performance and realised a generating efficiency of 90%. The micro CHP systems can be easily connected to the national grid by the application of the inverter. As an integral part of the system it coverts direct current to alternating current to allow the electricity generated to be fed back into the grid. The application of the inverter reduces initial unit cost and makes it possible to achieve 100% utilisation of the units.
