Project Case | Estonia: 2 Sets of 250kW Hybrid Inverters + 1.1MWh Energy Storage System

Bluesun has successfully completed another commercial energy storage project in Europe. Located in Estonia, the project integrates two 250kW hybrid inverters operating in parallel with a 1.1MWh lithium battery energy storage system.

Designed for commercial applications, the system helps improve renewable energy utilization, enhance backup power capability, and provide more reliable day-to-day energy management.

Parallel Hybrid Inverter Configuration

The project uses two 250kW hybrid inverters connected in parallel, allowing the system to deliver higher output while maintaining flexible and stable operation under different load conditions.

Working together with the battery storage system, the hybrid inverters intelligently manage solar generation, battery charging and discharging, and power consumption to improve overall system efficiency.

1.1MWh Battery Storage for Stable Energy Management

The 1.1MWh lithium battery system provides sufficient storage capacity for daily energy optimization and backup power support.

By storing excess electricity and releasing it when demand increases, the system helps reduce dependence on the grid while improving energy flexibility and operational reliability.

For commercial and industrial users, battery storage also supports peak shaving, load shifting, and greater utilization of renewable energy resources.

Designed for Commercial Energy Applications

This solution is suitable for factories, warehouses, industrial parks, commercial buildings, and other facilities that require stable power and intelligent energy management.

Compared with conventional power systems, integrated solar and storage solutions help businesses improve energy independence while preparing for future electricity demand.

Bluesun provides complete commercial battery energy storage systems for different project sizes and application scenarios.

Supporting Energy Storage Growth in Europe

Across Europe, more businesses are deploying battery energy storage systems to improve power reliability, reduce electricity costs, and make better use of renewable energy.

The Estonia project reflects this growing demand for flexible and scalable commercial energy storage solutions. To better support customers across Europe, Bluesun also offers EU overseas warehouse services, helping shorten delivery times and improve local project support.

With extensive experience in photovoltaic modules, hybrid inverters, lithium batteries, and commercial BESS solutions, Bluesun continues to deliver reliable clean energy technologies for customers around the world.
