The Itaipu Technological Park, which is near the city of Foz do Igua\u00e7u, is a Brazilian research centre for green energy. Together with energy provider\u00a0Companhia Paranaense de Energia, they have been trialing a domestic Energy Storage System (ESS) using Solar Power and Sodium Nickel Chloride batteries. The research and development project is supported by Brazilian Electricity Regulatory Agency.<\/p>\n

Senior Engineer Valentin Diaz says \u201cWe plan to integrate Victron energy products to other research projects and we are happy with the results so far\u201d<\/p><\/div>\n

By the end of 2019 the first of seven planned ESS prototypes began operation using Salt batteries. A swiss-made 48TL200, FZSonick\u00a0battery was chosen, for which a bespoke charge algorithm was programmed into the system’s Color Control GX\u00a0(CCGX).<\/p>\n

The Victron CCGX is the communication device which sits at the heart of private power plants, receiving data, monitoring status, and controlling charge\/discharge parameters.<\/p>\n

For the Itaipu Technology Park trial changes were made to the CCGX’s Venus Operating System software (Linux Kernel), allowing the implementation of the desired charge-control algorithm and Battery Management System (BMS) parameters.<\/p>\n

The CCGX’s broad range of third-party-manufacture product compatibilities, together with its user-definable programming options makes the CCGX a versatile and popular choice – particularly as it connects to Victron Energy’s free-to-use remote monitoring platform VRM<\/a> – allowing systems to be monitored and controlled from anywhere in the world. The facility to remotely monitor this pilot project was pivotal for the engineers at Itaipu.<\/p>\n

The 6 kVA ESS (18 kWh capacity) prototype has applications for domestic rural and city dwellers – ironing out power grid issues such as voltage fluctuations and power outages. Switching times are so fast that the installation acts as an uninterrupted power supply.<\/p>\n

Further improvements will be done in a second prototype in order to reduce weight and size of the proposed solution.<\/p><\/div>\n
