Delta fosters a great variety of new PV Inverters, energy storage systems and EV charging solutions featured at Intersolar
Also Delta’s Hybrid E5 energy storage system features a 95 percent high charging efficiency of DC electricity from the PV system directly to its own 6 kWh lithium ion battery. Two newly-launched electric vehicle (EV) chargers, an ultra-fast 150kW DC capable of charging 4 EVs imultaneously, and a quick 25 kW DC wallbox, are the ideal infrastructure for the growing network of EVs around the world.
Solar PV inverters made especially for commercial applications
Thus, Delta’s new flagship inverter model, the 3-phase transformerless M80H series, offers maximum 88 kVA output power and industry-leading peak efficiency of up to 98.8 percent. Other value-added features are 2 MPP trackers and a high maximum input voltage up to 1100V allow for extra flexibility in system design and better performance in challenging conditions.
Rugged die-cast aluminium chassis and wiring box feature IP65 enclosure rating designed for outdoor installation even in harsh environments. All-in-one design which greatly reduces the need for costly external devices. In fact, it includes built-in DC switches and AC and DC surge protection devices (SPDs). Multiple communication interfaces are available such as RS-485 and optional Ethernet.
The M30A series transformerless 3-phase inverter is also suitable for commercial applications given its added-value characteristics, such as maximum power output of 33 kVA, excellent power density and high peak efficiency of 98.5 percent. It also offers wide input voltage range of 200 to 1,100 volts and 2 MPP trackers. Asymmetrical loading (33/67 percent) is also possible, ensuring maximum yield in large commercial rooftop installations with multiple roof orientations.
The M30A is approximately 30 percent lighter than its predecessor model (Solivia 30TL) and improvements in size are also evident. It also features built-in Type II AC/DC SPDs and string fuses. Excellent resistance to harsh outdoor conditions with IP65 enclosure rating for the electronics compartment and the AC plug.
The battery energy storage system at a glance
The Hybrid E5 energy storage system is composed of the E5 hybrid inverter as well as an external cabinet equipped with a 6 kWh Li-ion battery, a power meter and a smart monitor. The Hybrid E5 storage system is designed for new PV systems and boasts a high charging efficiency up to 95 percent of DC electricity from the PV array to the battery without additional equipment needed. The system also includes greater flexibility and simplified installation as inverter and cabinet are separate.
The smart monitor not only controls the E5 inverter and battery functionality in an optimized way but it also serves as a gateway for visualization via mobile devices. The E5 hybrid inverter offers high peak efficiency (PV to Grid) of 97.2 percent and nominal continuous power output of 5.0 kW. It has built-in customized energy management modes for various customer needs.
Two new EV charging solutions
Delta is exhibiting two new EV chargers at Intersolar 2016. The innovative 150 kW DC Ultra-fast EV Charger is capable of charging up to 4 EVs simultaneously as it supports CCS-200A, CHAdeMO-125A, Type2-63A as well as Type2-32A standards, meaning it covers practically all EVs. With output power of up to 150 kW DC and up to 65 kW AC users will experience a remarkable improvement in charging times especially when EVs with larger battery capacity and longer driving ranges enter the market.
Operators taking this EV trend into consideration for their investment in charging infrastructure will be able to provide more attractive charging services to their clients in coming years, a key success factor in their EV charging business.
In addition, the newly-launched 25 kW Wallbox DC Quick EV Charger, is capable of enhancing convenience to system integrators as it boasts dual output as well as pluggable modular power system architecture for a significant reduction in installation and maintenance costs. Its quick-charging nature (the 24 kWh battery of a Nissan Leaf can be recharged from 0 percent to 80 percent in approx. 40 minutes, under certain conditions), RFID and mobile app user access, offer greater convenience to EV users in several commercial applications such as auto parking, EV fleet charging and even residential.
