Sunway – Model M PLUS – Single Phase Solar Inverter with Transformer

From Solar Energy- Single-Phase Solar Inverters0SHARE 

The best solution when the presence of an integrated transformer is requested by regulations or by the functional requirements of a unit, a plant or a network. SUNWAYTM M Plus is the ideal single phase inverter for compact sized grid-connected use on a network, for power values from 2kWp to 7 kWp of the photovoltaic field.  Reliable: it guarantees quality and the perfect operation of the plant, being protected even in case of unreliable networks. The solidity and strength of the product are guaranteed by high quality and very strong materials.
