Smart Solar + Storage Powers a Greek Business: RENAC’s 50kW/104kWh C&I ESS Delivers Savings and Resilience in Macedonia

With high electricity prices and extreme seasonal temperatures, a forward-thinking enterprise in northern Greece turns to RENAC for a tailored, reliable energy solution.

Facing persistently high commercial electricity rates and an unreliable grid, a business in Macedonia, Greece, sought a smarter way to manage energy costs while enhancing power resilience. The answer? The RENA1000 Commercial & Industrial (C&I) Energy Storage System from RENAC—delivering 50kW/104kWh of intelligent solar-plus-storage capacity.

Reliable, Green Power for a Modern Enterprise

Located in Macedonia—a region known for its strong solar irradiance (over 2,700 sunshine hours annually)—the business operates critical loads that demand stable, uninterrupted power. To reduce dependence on the grid and hedge against volatile energy prices, it deployed one RENA1000 all-in-one energy storage unit configured for self-consumption.

The system integrates a 50kW hybrid inverter, a 104kWh battery cabinet, and RENAC’s built-in Smart EMS (Energy Management System)—all in a compact, modular design ideal for space-constrained commercial sites.

Engineered for Real-World Conditions

While often grouped under “Mediterranean climate,” Macedonia actually experiences a temperate continental climate:

Summer highs exceeding 40°C
Winter lows dropping to –10°C
Large diurnal temperature swings

To ensure year-round reliability, the RENA1000 unit underwent rigorous validation across a wide operating temperature range of –20°C to +50°C, proving its robustness in real-world European conditions.

Key Features That Set RENA1000 Apart

✅ No-parallel battery architecture: Eliminates circulating currents, enhancing long-term safety and performance

✅ Triple-power compatibility: Seamlessly switches between PV, grid, and backup generator—ensuring continuous operation

✅ Modular, all-in-one design: Simplifies installation and maintenance

✅ Smart EMS platform: Enables real-time monitoring, dynamic load management, and future integration with building energy systems or VPPs

Tangible Results, Measurable Impact

“The system was quick to install and has already demonstrated significant cost savings—projected to exceed €19200 annually.”
