New ABB solar inverters* for residential and commercial buildings as well as a megawatt station for photovoltaic power plants are being introduced to the market for the first time at the Intersolar fair in Munich, Germany - the world’s largest exhibition for the solar industry.
By ABB Communications
ABB string inverters (PVS300) target solar installations in residential buildings as well as small and medium-sized commercial and industrial buildings. The new transformerless single-phase inverter series has a power range from 3.3 to 8 kilowatts (kW).
It converts energy generated by solar panels into electricity that can be fed into the power network.
The new ABB string inverter PVS300 and control unit.
The string inverter’s all-in-one design includes built-in protection functions which reduce the need for costly and space-consuming external protection devices and larger enclosures.
Compact, reliable, safe
The result is a more compact, reliable, safer and cost-effective solution, especially for installations using multiple inverters.
The heart of the inverter is an intuitive and versatile control unit equipped with a graphical display. It offers a comprehensive range of key functionalities that are easy to use with the built-in assistants and help menu.
The control unit has three different mounting options covering all user requirements. It can be integrated with the inverter housing, or mounted separately on a wall to monitor inverter performance from outside the installation room.
It can also be wirelessly connected so the inverter can be installed in a remote part of the site, and monitored wirelessly from inside the home or main building.
A turnkey solar solution
The ABB megawatt station is a container housing all electrical equipment needed to rapidly connect a photovoltaic power plant to a medium-voltage electricity grid.
The station is a turnkey solution, complementing the recently launched ABB central inverter offering. It houses two 500 kW ABB central inverters, an optimized transformer, medium voltage switchgear, monitoring system and solar generator terminal boxes.
The steel-framed insulated container comes complete with a concrete foundation, also designed and produced by ABB.
The ABB megawatt station is a turnkey container housing all electrical equipment needed to rapidly connect a photovoltaic power plant to a medium-voltage electricity grid.
The station’s thermal insulation lets it operate in harsh temperatures and humid environments. The station is designed for at least 25 years of operation.
The total package weighs only 20 tons, which is less than half the weight of conventional concrete stations.
At 50 square meters, the Megawatt station is about 15 percent smaller than other standard container solutions on the market.
It is easier and less expensive to transport, because registered heavy goods vehicles or large cranes are not necessary to move it.
Depending on the size of the PV power plant, several ABB megawatt stations can be combined to meet the demand capacity.
*An inverter is a device used to convert electricity from direct current (DC) to alternating current (AC), which can be fed into the power network
