RPS TL-UL System
Bonfiglioli Photovoltaics is now offering the UL-certified RPS TL inverter series. Leveraging the same reliable technology as its European version, the RPS TL-UL system offers a solution for the North American market that is unsurpassed in terms of proven, trusted technology.
Over 2 GW are currently installed globally with Bonfiglioli PV inverter technologies in large, utility-scale installations. With the addition of UL-approved inverters for the North American market, Bonfiglioli continues its commitment to solar and green technologies and strives to brighten the North American market as it has done in Europe.
ReliabilityThe RPS TL-UL by Bonfiglioli is a uniquely-designed, high-powered photovoltaic inverter system that provides maximum energy harvest. With multiple, independent MPPT channels, the RPS TL-UL ensures maximum system reliability: a single fault will affect only one subfield, while the balance of the system continues to operate, which minimizes loss of energy production.
Flexibility and ScalabilityThe RPS TL-UL boasts one of the widest ranges of inverter ratings on the market today (from 367 kWac to 1.40 MWac), ensuring an optimal matching with any size array.The fully scalable, modular architecture also offers greater design flexibility and more options for managing workload.
Quality and PerformanceBonfiglioli RPS TL-UL inverters offer the following:• A versatile design that performs well even in the
event of unexpected system failures• Lower maintenance costs and longer expected
lifetime• Top-quality electro-mechanical components reduce
the incidence of failures, which in turn reduces repair costs and increases production time.
Proven Technology and LongevitySupported by more than 40 R&D engineers and over 25 years of engineering excellence in power conversion technology, Bonfiglioli has the required footprint, experience and infrastructure to develop and deliver complete cost-effective solutions, from MPPT tracking to utility interconnection.
In addition, the overall business composition of Bonfiglioli ensures financial stability to support installations long-term, and to provide and support an uptime guarantee and wide range of extended warranty options.

The scalable, modular architecture of the RPS TL-UL offers greater system flexibility and more options for managing working load, making Bonfiglioli an ideal partner for commercial and utility-scale installations.
Available in Master-Slave or Multi-MPPT configurations, the RPS TL-UL system includes floating or grounded arrays up to 1000Vdc.
Master-Slave ConfigurationThe Master-Slave configuration intelligently manages the working load of each module in order to maximize conversion efficiency and provide an extended working life.The automatic disconnection of individual modules during fault conditions ensures the effect on system energy production is minimized by allowing the balance of the system to operate.The Master-Slave system is ideally suited to provide the most benefit in efficiency under partial load conditions and will allow the system to start earlier in the morning and stop later in the evening.
Multi-MPPT ConfigurationThe Multi-MPPT configuration provides independent control for multiple sub-arrays, making this configuration ideally suited for solar applications with different irradiance profiles, unmatched solar panels or multiple surface slopes. In this configuration, the system is able to minimize the solar array mismatch losses by searching for the best voltage operating value that can maximize power production. This system also enables applications with different electrical characteristics to be used together, which maximizes efficiency and increases productivity.
Comprehensive Grid Management• Anti-islanding with grid voltage and frequency
protection according to UL1741 & IEEE 1547• Fault ride-through including high voltage, low
voltage and zero voltage capability.
(for more details on grid management, see page 13).
Technical Overview• Wide range of inverter power ratings from 367
kWac to 1.40 MWac• Modular inverter system with up to 7 independent
MPPT inputs• Certified to UL1741 and CSA 107.01-01 standards• Compliant with IEEE1547 standards• Full suite for power management functions
including Fault Ride Through• Maximum efficiency up to 98.6%• DC Load Break disconnect for each module to
provide isolation from the solar array• Includes main AC breaker to provide overall
protection for inverter lineup• Suitable for floating or grounded (positive or
negative) array configurations.
Bonfiglioli has established the assets, competence, and technical prowess to successfully deliver and install commercial and utility-scale power systems anywhere in the world.

The RPS TL-UL inverter includes a comprehensive set of grid management and protection functions with the flexibility to meet all relevant grid management codes and practices in North America. In the most standard configuration, the RPS TL-UL system includes anti-islanding with grid voltage and frequency protection according to UL1741 & IEEE 1547 to ensure that the inverter quickly and safely disconnects from the local utility.
The RPS TL-UL is also designed with a comprehensive suite of power management and grid support functions for advanced utility power plants.This capability was first developed in response to the German BDEW standards and is now offered by Bonfiglioli to meet electrical grid standards in North America.
The functions of the advanced configuration include:• Active power curtailment via SCADA interface.• Reactive power control locally or via SCADA
interface.• Fault ride-through including high voltage, low
voltage and zero voltage capability.• Dynamic grid support and voltage control
capability.• Controlled power ramps to minimize disturbances
on grid.• Compatible with FERC 661A, NERC PRC 024, WECC
ONF Plan and CAISO IRRP.• Other grid profiles possible.
