  Delta Ushers a Sustainable Future with its Cutting-Edge Energy Storage Solutions and PV Inverters Unveiled at Intersolar Europe 2017
Teningen, Germany, May 18, 2017
Delta, a global leader in power and thermal management solutions, will present a broad portfolio of high-efficiency PV inverters and battery energy storage solutions at Intersolar 2017 Europe. The energy storage system ES30 series, an all-in-one and highly scalable solution integrating Li-ion batteries for up to 90kWh capacity and more than 2 hours of continuous 30kW back-up power; and the new high-performance string PV inverter M88H series, featuring maximum 88kVA output power, industry-leading peak efficiency up to 98.8%, active cooling and an electromagnetic interference (EMI)-proof design, will be key highlights of Delta’s showcase.

By leveraging its core competence in power electronics, leadership in energy conversion efficiency and expertise in system integration, Delta develops intelligent solutions capable of optimizing the adoption of solar PV power and energy storage not only to support the transition megatrend from centralized energy supply to decentralized renewable energy plants, but also to enable greater electricity costs savings as well as a more reliable and eco-friendly energy supply.

Visitors at Delta’s Hall B3, Stand 140 in Intersolar 2017 Europe will have close access to key innovative and eco-friendly solutions such as:

Commercial Battery Energy Storage System ES30 Series:

The ES30 is a three-phase 90kWh Li-ion battery energy storage system suitable for commercial and industrial applications. The AC-coupled system in a standard 19” rack features a flexible and modular design scalable up from 6kWh to 90kWh battery capacity. A 30kW Power Conversion System (PCS) with an impressive 0.99 AC output power factor and integrated Battery Management System (BMS) are included in the scope of delivery.

The system also includes:

- 30kW continuous power for more than 2 hours (with 90kWh battery capacity).
- Modular and flexible design allows power expansion up to 90kWh.
- Reliable and high quality Li-ion battery modules with cycle life greater than 6,000 cycles.
- When combined with the Delta PPM P3E Power Meter and the R4 Smart Monitor Energy Management
System, many different customized energy usage modes can be realized.

Applications include:

- Limiting feed-in power to the grid from solar power generation according to a dynamic trend
or by a fixed value.
- Maximized self-consumption of the self-produced energy for commercial buildings or small
- Peak-shaving and –shifting to allow the lower cost electric power to be stored to the
battery bank as energy reserve, and the energy is then dispatched during peak rate periods
for lower electric power cost.
- Can be utilized to control reactive power to stabilize grid voltage.

Solar PV Inverters for Commercial Applications:

High-power and high-efficiency string inverters are ideal for large commercial and ground-mounted PV plants with megawatt-sized solar arrays where optimum yield is important to ensure a valuable investment return from the system. Thus, Delta’s new flagship inverter model, the 3-phase M88H series, offers maximum 88kVA output power, active cooling and industry-leading peak efficiency of up to 98.8%.

- Flexible DC/AC overload capabilities.
- Metallic housing for perfect EMI performance.
- Open communication possibilities with highly experienced partners in monitoring solutions
enabling safe and proper remote plant control.

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.

Residential Battery Energy Storage System:

The Hybrid E5 energy storage system is composed of the E5 hybrid inverter as well as an external cabinet equipped with a 6kWh 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% 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.
- High peak efficiency (PV to Grid) of 97.2% and nominal continuous power output of 5.0kW for
E5 hybrid inverter.
- Built-in customized energy management modes for various customer needs.

Welcome to Delta’s showcase at Hall B3, Stand 140 at Intersolar Europe 2017 in Munich from 31 May – 2 June.
