eos-system: An Innovative and Expandable Photovoltaic Management and Control Solution

rotecting the environment is a fundamental ideal that requires dedication and care, which is why every solar

project is a vital project. It needs the same attention that we devote to the things we value most.

When developing the control system for photovoltaic plants, care and attention are essential values for Carlo Gavazzi. This ensures the solar investment is a solid investment.

The Carlo Gavazzi solution develops with the Eos-Array and the Eos-Box depending upon the requirements and complexity of the photovoltaic plant.

Eos-Array and Eos-Array Lite: is a system comprised of individual modular elements that, when interacting with one another, provide efficient local control to the solar plant. Whether it’s a small/medium or high power plant, you are assured there is effective information management. The Eos-Array provides a compact, simple, versatile and innovative solution.

Eos-Box: is a web server that controls and supervises the whole installation, acquiring information from: • Eos-Array groups • Inverters• Energy meters • Interface protection

The Eos-Box provides information in a quick and automatic fashion via the internet, so the data is available wherever you are.

How can you protect your investment?A solar installation, whether it’s small or large is always an important investment.

You can protect your investment if:• You meet the performance limits!• You know the system is working properly!• You realize the anticipated solar electric performance level!• You prove that you’ve produced results!• You payback the investment!

How much money will you lose if your solar system stops for three days?To ensure you don’t lose money — you need a CONTROL solution.

Reliable control requires independent control!Providing you with dependable and accurate data, promptly advising when: • The photovoltaic modules are not performing• The photovoltaic modules are removed or not connected• The inverter failsFurthermore, focused control on every single string provides an immediate localization of the fault, thus significantly reducing the service time and the production downtime costs.

Adding a control solution is now easy!

Benefits

l String box with breaker, surge and fuse protection.

l String box with breaker, surge and fuse protection with added measurement features.

l String box with breaker, surge and fuse protection with measurements of V-A-kW-kWh (VMU-S), the temperature of the PV cell, the air temperature, the power of

solar irradiation and the speed of the wind (VMU-P)

and extended control features (VMU-O).

l A perceived low cost solution,

which becomes very expensive in large installations,

because of the long trouble-shooting time and the relevant

production downtime.

l Replacement of standard “positive” fuse holders with similarly sized Eos-Array

VMU-M and VMU-S solution provides cost effective control without the need for replacing

the existing string box.

l Full local variable measurement with data and local alarms, breaker(s) and surge protection status logging for efficient and effective string and plant control.

The major control solution today

• Has a fixed number of string controllers

• Is space consuming

• Is complex to wire

• Is difficult to repair when a failure occurs

• Has yield data available primarily from the inverter

Eos-Array LiteEos-Array Lite

Eos-Array Lite is the solution for those photovoltaic applications where less sophisticated control is needed. This solution is based on the same overall concept of the Eos-Array such as modularity, integrated string fuse protection, but focusing on the measurement and control the string controller's current and voltage. As an undoubted result, the Eos-Array Lite provides immediate string failure detection, the location of the failure or if their is an incorrect or missing PV panel connection. This results in faster plant commissioning and notification that preventative maintenance is required.

Eos-Array Lite is specifically developed to be integrated in either a small or medium size photovoltaic plant where all of the most significant data is transmitted via RS485 Modbus at a maximum speed of 115.2 kbit/s to the local PV Energy Management System.

An essential working tool is offered with the Eos-ArrayLSoft freeware software, which allows the user to easily configure the Eos-Array Lite, check the communication wiring and remotely read the available measurement data.

Maximum freedomof choice

As each application has unique requirements, Carlo Gavazzi has designed

distinctive products for solar applications, offering an advanced control solution:

• The Eos-Array• or the Eos-Array Lite, a simplified

control solution

Eos-Array Lite Synthesis of

controlEos-Array completeness of control

The Eos-Array and Eos-Array Lite are provided with a specific communication

and power supply bus, that allows the modules to communicate with each

other in any needed configuration, thus simplifying the installation.

Versatility: a characteristic that makes work easier The Eos-Array is modular and can be composed of: VMU-M the master unit and data logger; VMU-S the string controller; VMU-P the environment variable(s) and VMU-O the I/O unit: a mixed combination of up 16 units in total.Some tangible advantages:• Measurement and control functions are split into independent modules, thus

improving the critical system reliability• String efficiency and balance of system (BOS) efficiency measurement are

fundamental parameters to evaluate the yield of the photovoltaic plant• Local alarm management provides fast and easy identification

Information and control... everywhere

• Integrated fuse protection provides cost and installation time savings• Easy application adaptability - the customer can choose according to their project philosophy which modules best fit into their application, thus giving them the freedom to find different solutions for their application challenges• Future expansion of features capabilities are based on usage of different modules and quantities, thus meeting application needs from small (10kWp) to large solar PV plants

• Multicolor LEDs provide immediate feedback on variables, alarms, fuse status and communication, showing the relevant details on the display
