Solar production and energy back-up system – Case study

PROJECT SUMMARY
  • Project: Italian Consulate
  • Location: Casablanca, Morocco
  • Application: Solar plant and energy storage
NIDEC'S ROLE

The Power Conversion System supplied by Nidec ASI enables the Italian Consulate to use power generated by its solar panels or pull electricity from the grid. Any excess power it generates is converted from AC to DC voltage and stored in three on-site batteries that can hold up to 23 kW each.

In the event of an outage, the system operates in “off-the-grid” mode, using power stored in the batteries to provide electricity to the consulate until grid power resumes. Nidec ASI’s PCS includes a control system that can, if necessary, manage energy flow in real time to ensure stable power supply. The charging and discharging of the batteries, which are equipped with their own Battery Management System (BMS); are controlled by a dedicated DC/DC converter.

Scope of Supply
Casablanca, Morocco
THE CHALLENGE
To increase renewable energy production and ensure a continuous emergency power supply

The power supply in developing nations, such as Morocco, is not always as reliable as some foreign consulates’ needs demand.

Wishing to reduce its own dependence on the local power grid, while also serving as an example to other consulates with aspirations of “going green,” the Italian Foreign Ministry in Casablanca undertook a program to become a laboratory of sustainable energy production. In particular, it wished to create a source of renewable energy that could supplement the power it received from the grid and, in emergency situations, replace it.

THE SOLUTION
Solar production and energy back-up system

A green initiative launched by the Italian Foreign Ministry includes multiple projects to increase its energy independence, including a 40 kW solar plant installed on the roof of the Italian consulate in Casablanca, which connects to an Energy Storage system.

The solution not only provides the Italian consultate with its own independent energy supply for emergency situations, it also will lower carbon emissions by approximately 31.72 tonnes a year.
