18 × 125kW PCS Deployed in Estonia for Solar Self-Consumption & Grid Stability

Project Background

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

As solar penetration increases, intermittency and grid volatility become critical challenges—especially 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–500 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
⚡ ≤10 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
✔ Improved solar self-consumption
✔ Enhanced grid resilience and power quality
✔ Reduced dependence on the public grid
✔ Future-proof modular design for system expansion

This Estonia project demonstrates how modular PCS solutions from Gogreen help PV operators move beyond pure generation—toward stable, flexible, and independent energy systems.
