Yaskawa Selectria Solar, a subsidiary of Yaskawa America, Inc., and manufacturer of photovoltaic (PV) inverters, will be showcasing its latest offerings during RE+ 2025 in the US. The company plans to highlight its 2 new products, tailored for utility and large rooftop applications in the US.
Central Inverter for Utility
The XGI 1500-1MW series central inverter, promoted for ground-mounted utility PV projects,
is equipped with a centralized MPPT channel with an operating range of 860 V to 1,450 V DC. It is designed to connect 4 PV input terminals (+ and -). The positive pole (+) of each terminal is protected with an 800 A fuse, while the negative (-) is grounded. According to the datasheet, its 1,500 V-rated MPPT can support a maximum operating PV power of 1,020 kW and current not exceeding 1,183 A. Engineered for DC/AC oversizing of 250%, it can support up to 2.5 MW DC with a corresponding 3-phase output of 1 MW.
On the safety front, each positive terminal on the PV input side of the central inverter is protected by an integrated fuse for overcurrent, while the negative carries 0 potential. In addition, these terminals are equipped with an upstream safety feature consisting of 4 DC isolator switches, each with a 600 A capacity, designed for block-wise PV array isolation during maintenance or fault occurrences. According to the company, its negative PV terminal grounding enables mitigation of potential-induced degradation (PID) in connected PV modules.
The inverter has a modular design, which supports combining 3, 4, or 5 inverters with factory-assembled Power-Skids. This facilitates an expandable output power range that can vary between 2.25 MW and 4 MW, according to the customer’s needs. According to the company, Power-Skids are pre-wired and tested in conjunction with AC combiner boxes in its factory. A transformer can also be integrated on demand. In addition to the upscaling capability, its bidirectional charging functionality makes it adaptable with either a DC-coupled or an AC-coupled energy storage system (ESS).
Miles C. Russell, Director of Product Management at Yaskawa Solectria Solar, said, “We are very excited to introduce this new line of Utility-Scale inverters and the patented MegaSkid building block for large projects”. He added, “This will accelerate our growth in the Utility-scale solar market and enable us to bring the very best of our technology to our customers”.
String Inverter for Distributed Generation (DG)
Targeted at large-scale rooftop installations, the PVI-100TL-480 series transformer-less string inverter features 6 MPPT channels, each carrying up to 4 PV strings and capable of up to 120 A of current. Compared to the central inverter mentioned above, the latter’s MPPT is designed for a lower system voltage of up to 1,000 V DC. However, it features a wider MPPT operating voltage range of 200 V to 1,000 V. Rated for up to 200% DC/AC overloading, the string inverter can deliver up to 100 kW 3-phase AC power.
Unlike its displayed central inverter’s fuse connected positive (+) pole, the string inverter’s positive (+) and negative (+) terminals are protected by built-in glass fuses against overcurrent events. Meanwhile, the integrated surge protection device (SPD) on both the AC and DC sides shields the entire inverter from voltage surges, typically stemming from external lightning. One of the standout features of this inverter, the company pointed out, is its module-level rapid shutdown (MLRSD) feature, which protects the system and the property in the event of fire. This safety feature is enabled by the company’s so-called ‘wirebox’, which integrates a powerline communication transmitter, supplied by APsmart.
The company offers a product warranty of up to 5 years for the utility-scale inverter and 10 years for the string inverter.
Alongside the abovementioned products, Yaskawa will promote its Selectria O&M ECO-SYSTEM for full-circle operation and maintenance (O&M) services to its clients.
