AURORA UNO-2.0 and UNO-2.5, from Power-One

Unique features:

• The UNO 2.0 and UNO-2.5 are the ideal size for the average rooftop installation, and have either a 2 kilowatt (kW) or 2.5 kW output
• The UNO-2.0 and UNO-2.5 single phase inverters are Power-One’s smallest residential inverters
• The UNO-2.0 inverter series offers features such as a special built-in heat sink compartment and a front panel user interface
• The UNO-2.0 inverter series has a wide input voltage range which makes the inverter suitable to low power installations with reduced string size.

Testing credentials:

• The UNO-2.0 inverter series has met EN 50178, AS/NZS3100, AS/NZS 60950, EN61000-6-1, EN61000-6-3, EN61000-3-11 and EN61000-3-12 safety and EMC standards.

• Power-One’s UNO-2.0 inverter series is designed as a completely sealed unit so it can withstand extreme outdoor weather conditions
• The UNO-2.0 series features a high speed maximum power point tracker, and offers real-time power tracking and improved energy harvesting
• The UNO-2.0 series has an efficiency of 96.3 per cent
• Each inverter is set on specific grid codes which can be selected on-field.

CL 36.0 (36 kW), CL 48.0 (48 kW) and CL 60.0 (60 kW), from Fronius

Unique Features

• The Fronius CL series of solar inverters are the only inverters above 30 kW to be included on the Clean Energy Council’s approved inverter list
• The Fronius CL series comes in three nominal output power classifications, making it suited for PV systems of up to several hundred kilowatts
• The Fronius CL is comprised of up to 15 identical power modules that work together using the Fronius MIX ™ concept. The MIXTM turns on and off the power modules to enable the CL to adjust to the variance in insulation that occurs throughout a normal day
• The Fronius MIX™ concept ensures that the inverter remains in operation, even when there is a defect in one of the power modules, which can be easily removed and replaced when required
• MIXTM evenly shares the workload among all the power modules, which helps to prolong the effective life of the inverter.

Testing Credentials

• The Fronius CL series has received certification according to AS4777.2, AS4777.3 and AS3100 standards, and has received approvals for DIN V VDE 0126-1-1, IEC 62109-1, EN 50178, EN 50438, EN 61000-6-3, EN 61000-6-2, EN 61000-3-12, EN 61000-3-11, EN 61000-3-2, CER/06/190, G59/2, G83, CE, UL and C-Tick
• The Fronius CL series has a 100 per cent inspection rate for each product delivered.

Additional features

• The Fronius CL series features a hermetically sealed ventilation concept, and therefore no external air can enter the power electronics of the power module. The inverter temperature is optimally controlled as cool air passes over the heat sink which is separated from the circuit boards
• The Fronius CL series also features an integrated COM/Interface Card which allows easy compliance to system monitoring options such as Fronius DATCOM.

Sunny Tripower, from SMA

Unique features:

• SMA’s Sunny Tripower is a three-phase transformerless solar inverter that can be applied to almost any module configuration
• The Sunny Tripower is available in five power classes, ranging between 8 and 17 kW
• The Sunny Tripower enables true three-phase feed-in of solar energy, making it easier to design a plant with high precision
• The Sunny Tripower plays an important role in grid management, as it helps to maintain frequency and voltage stability by using reactive power.

Testing credentials:

• The Sunny Tripower was awarded the Innovation Prize at the Symposium for Photovoltaic Solar Energy in Germany
• The Sunny Tripower was listed as an “A+,” product by Photon International magazine in 2010, as features one of the highest efficiencies ever measured by Photon’s assessment tests
• The Sunny Tripower has met CE, VDE 0126-1-1, G83/1-1, RD 1663/2000, PPC, AS4777, EN 50438*, C10/11, PPDS, RD 661/2007, G59/2, IEC 61727, ENEL-Guida, and UTE C15-712-1 testing standards and credentials.

• The Sunny Tripower has a peak efficiency of over 98 per cent
• The Sunny Tripower is user-friendly, cost effective and comes with a comprehensive safety concept.
