Project Overview

Nestled in the historical city of Veliko Tarnovo, Bulgaria, Park Hotel Raya Garden is setting a new benchmark for sustainable hospitality. By integrating dynamic battery storage and EV charging into its existing solar infrastructure, the landmark hotel and restaurant has transformed its facility into a self-sustaining, future-ready energy ecosystem.

The Challenge

As modern hospitality demands evolve, Park Hotel Raya Garden faced three core energy objectives:

• Maximize Solar Self-Consumption: Fully harness on-site PV generation rather than exporting excess daytime energy back to the grid.

• Prepare for Future Mobility: Seamlessly add high-power EV charging infrastructure without triggering costly grid upgrade fees or overloading local transformers.

• Maintain Operational Reliability: Ensure uninterrupted, quiet, and reliable power flow across the hotel and restaurant facilities year-round.

EENOVANCE Solution

To meet these demands, installer Energy Home selected the EENOVANCE E-MATE 125-261-L outdoor energy storage cabinet. Installed on a compact concrete base directly adjacent to the hotel’s car park, the two-unit configuration delivers a robust 522.5 kWh total rated storage capacity.

Key System Highlights:

• Rated Capacity: 261.25 kWh per unit (522.5 kWh total)

• Cell Technology: LFP 3.2 V / 314 Ah high-density cells

• Thermal Management: Liquid cooling for optimal cell temperature distribution

• Service Life: 8,000 deep-discharge cycles

• Comprehensive Safety: IP55 protection rating, active combustible-gas detection, and aerosol fire suppression
