HBOWA supplied a 100kW Megarevo inverter and a 200kWh LiFePO₄ battery energy storage system for a hotel project in Romania. The system is designed to improve solar self-consumption, reduce peak electricity demand, and provide backup power for the key hotel loads.

Project Overview

Customer Challenge

The hotel needed a more stable and cost-effective power solution for daily operation. Without battery storage, excess solar energy could not be fully used, and the hotel still had to rely heavily on grid power during high-demand periods.

Energy Storage Solution

HBOWA provided a 100kW / 200kWh energy storage system combined with a 100kW Megarevo inverter, 280ah battery cell, each battery pack is 14kwh, 14 pieces in a cabinet to reach 200kwh capacity as needed.

The system supports:

• Storing excess solar power during the day
• Discharging stored energy during evening and peak-load periods
• Reducing grid electricity consumption
• Supporting essential hotel loads during short power interruptions
• Improving the hotel’s overall energy management efficiency

Project Benefits

• Higher Solar Self-Consumption
  Stores unused PV energy and uses it when the hotel load increases.
• Peak Shaving for Hotel Loads
  Reduces grid demand during high-consumption periods.
• Backup Power Support
  Provides stored energy for lighting, reception, security, pumps, and other key loads.
• Lower Grid Dependence
  Helps the hotel use more self-generated solar power.
• Stable Commercial Operation
  Supports continuous hotel service and improves energy reliability.
