McNae Energy and Solar recommends and installs Enphase micro inverters and Fronius string inverters. Micro inverters are used in nearly all our residential installations, while String inveters tend to be used in larger commercial systems. The reasons for this are two-fold. First, because of the inherent advantages of micro inverter technology, and second, because of our huge buying power, we can install a micro inverter system at little more cost than a string inverter system.
String inverters work best for unshaded roofs and they are more cost effective for larger systems. We recommend Fronius string inverters. They are made in Austria and McNae Electrical Solutions is an authorised Fronius Service Partner. This means we can supply and service these quality inverters right down to on-site board replacement if necessary. Further information about why we recommend Fronius inverters can be downloaded from here.
In most cases, the recommended and most cost effective option is a hybrid string inverter with an integrated modular battery. For more on hybrid systems see here.
