46 S E P T E M B E R / O C TO B E R 2 0 1 8 New 1,500-V inverter The new 100- and 125-kW (111 and 132kVA) medium power CPS three phase string inverters are designed for ground-mount and carport applications at 1,500 Vdc. The units are high performance, advanced and reliable, designed specifically for the North American environment and grid. High efficiency at 98.8 percent peak and 98.5 percent CEC, wide operating voltages, broad tem- perature ranges and a NEMA Type 4X enclosure enable this inverter platform to operate at high performance across many applica- tions. These CPS inverters ship with either the standard or "centralized" wire- box. The standard wire-box includes touch safe fusing, surge protection and AC and DC disconnect switches. The new centralized wire-box is designed for sites benefitting from DC combining near the array and locating the inverters closer to the point of interconnection. Both wire-box versions employ the CPS sepa- rable, quick-connect wire-box design saving time installing and servicing the product. In addition, inserting the CPS Flex Gateway in either version wire-box enables communication, controls and remote product upgrades required in today's PV plants. The CPS Flex Gateway is a data communications and con- trols solution for the CPS inverter line that acts as a Modbus master data logger for controlling commercial and utility-scale inverter applications. This f lexible solution enables three parallel outbound communications options: (1) local pass- through Modbus data to third-party solutions, (2) ethernet based communica- tions to CPS Service for remote diagnostics and updates, (3) and a program- mable Ethernet XML SunSpec Data Exchange connection for customers who want to manage their data directly. Booth 504 Bifacial PERC LONGi Solar is displaying its high-performance Hi-MO3 modules at Solar Power International, which is a half-cut bifacial p-mono PERC module that hit the market earlier this year. The Hi-MO3 can reduce the levelized cost of energy (LCOE) by at least 10 percent compared to conventional products. Recently, LONGi Solar achieved a record-setting 23.6 percent front-side conversion efficiency on a p-type monocrystalline module, confirmed by the China General Certification Center. It uses half-cut techniques that reduce resistance losses and increase power by 5 to 10 W on average. Booth 528 Remove ballast from the roof OMG Roofing Products has introduced PowerGrip Universal (PGU) for solar rack systems on all commercial roofs. PowerGrip Universal can reduce or eliminate ballast, so there's less weight, mate- rial handling and labor required. Designed with performance in mind, PGUs offer 3,300 lbf of tensile, 2,500 lbf of shear and 2,000 lbf of compressive strength. It's one of the strongest anchors available. Made of heavy-duty cast aluminum, PowerGrip Universal is easy to install and can save time and labor. PGU transfers the load to the structural roof deck and does not require any membrane welding.
