PRO-33.0-TL-OUTD-SX-400

ABB Aurora Power-One PRO-33.0-TL-OUTD-SX-400 string inverter with DC switch, fuses and DC surge arresters

ABB string inverters cost-efficiently convert the direct current (DC) generated by solar modules into high quality three-phase alternating current (AC) that can be fed into the power distribution network (i.e. grid). Designed to meet the needs of the entire supply chain – from system integrators and installers to end users – these transformerless, three-phase inverters are designed for decentralized photovoltaic (PV) systems installed in commercial and industrial systems up to megawatt (MW) sizes.
A three-phase inverter from the world’s leading power technology company ABB, a global leader in power and automation technologies, brings decades of experience, technology leadership and application know-how from renewable energies to this new string inverter. Such experience and technology ensures high quality, safe and reliable solar inverters are delivered every time.
High power package for decentralized PV systems ABB’s three-phase PRO-33 string inverter is designed for medium and large decentralized PV systems either on large-scale commercial and industrial rooftops or ground-mounted PV plants. The inverter offers cost-efficiency in a high power, wall-mountable package with very high conversion efficiency.

The all-in-one design with built-in and monitored PV plant protection devices reduces the need of costly external devices. The single maximum power point tracker (MPPT) and optimized MPPT window are suitable for uniformshaped PV plants with long strings connected to the inverter. The high maximum DC input voltage of up to 1100 V gives PV plant designers extra flexibility and allows more PV modules to be connected in series to reduce cabling costs.

Highlights

• Compact, high power wall-mountable package
• High maximum DC input voltage of up to 1100 V
• Configurable all-in-one design
• Advanced grid support functions
• Safe and intuitive user interface
• Robust enclosure, with IP65 rating suitable for outdoor installation

Configurable all-in-one design The ABB PRO-33.0 string inverter comes in three product variants. The standard model with or without DC switch is designed for use with an external string combiner box. The all-in-one model with built-in string combiner box includes a DC switch, string current monitoring with alarm, PV fuses, monitored surge protection devices and tool-less solar quick connectors. The inverter’s all-in-one design, with built-in and monitored PV plant protection devices, reduces the need of costly external devices.

High total efficiency maximizes return on investment The PRO-33.0 inverter offers a high conversion and MPP tracking efficiency in all conditions. A flat efficiency curve provides high revenues in low and high radiation conditions. Fast and easy commissioning Fast PV plant commissioning is enabled via preprogrammed country grid code settings that are easily selectable. Extensive certification ensures wide grid code compatibility. Plug and Play DC and AC connectors enable fast and safe cabling. A touch protected installation area provides additional safety and comfort for inverter installation and maintenance.
