3rd Quarter 2015Electrical switching & drive systems & components
The recently completed installation of a grid-tied photovoltaic rooftop plant by Genergy and ABB value added provider, All Electrical has enabled the property owner to reduce reliance on daytime utility power. According to Warren Alistoun, design engineer at Genergy, in the period April to June 2015 the plant, located in North End, Port Elizabeth has reliably produced a total of 33,25 MWh of electricity. The building relies on the photovoltaic (PV) plant to augment utility electrical supply and is primarily occupied during the daytime hours, making it well suited for a grid-tied PV solution. The PV plant is rated to produce 100 kWp and relies on three ABB Trio 27.6 kVA inverters and a single ABB Trio 10 kVA inverter to provide the flexibility required by the design.
ABB’s Trio range of string inverters offers high levels of flexibility and control for system designers and installers, allowing for the optimal harvesting of energy from strings that are oriented in different directions. “The technology employed in these inverters delivers an efficiency rating of up to 98,2% due to the flat efficiency curves that ensure optimal performance at all output levels,” says Alessanda Romoli, ABB area sales manager, solar products. Advanced design features include a high efficiency integral heatsink compartment and a front panel display system. Furthermore, the system does not rely on electrolytic capacitors and as a result the product enjoys an extended lifetime.
