Project Background<\/h2>\n\n\n\n

Country: Republic of Estonia
Total PCS Capacity: 2.25 MW
\u2600\ufe0f System Type: PV + Energy Storage (4 MWh)

As solar penetration increases, intermittency and grid volatility become critical challenges\u2014especially for traditional PV plant operators. In this project, Gogreen supplied 18 units of 125 kW modular PCS to support a large-scale PV-plus-storage system, enabling higher self-consumption, improved stability, and greater energy independence.

Solution Overview
The project adopts Gogreen G-Flex Series Modular PCS (50 kW\u2013500 kW), built from standardized 125 kW power modules, offering flexible configuration and high reliability.

Key features include:
Bidirectional DC\/AC conversion for charging and discharging
\u26a1 \u226410 ms seamless switching (STS) to ensure uninterrupted power
On-grid & off-grid operation support
Integrated transformer & STS module
Modular architecture for scalable PV + storage systems

Project Value
\u2714 Improved solar self-consumption
\u2714 Enhanced grid resilience and power quality
\u2714 Reduced dependence on the public grid
\u2714 Future-proof modular design for system expansion

This Estonia project demonstrates how modular PCS solutions from Gogreen help PV operators move beyond pure generation\u2014toward stable, flexible, and independent energy systems.<\/p>\n\n\n\n
