Project Background for Commercial & Industrial Energy Storage

Hotels in the Philippines often experience voltage fluctuations and short power outages during typhoon season and periods of high electricity demand. Since hotels operate 24/7, stable power is essential for guest room lighting, air conditioning, elevators, security systems, and front desk operations.

To improve power reliability and maintain uninterrupted services, the hotel deployed a 100kW commercial energy storage system with battery backup support provided by SRNE.

100kW C&I Energy Storage System Configuration

Commercial Backup Power Solution

SRNE designed a commercial solar and battery storage system to help the hotel reduce grid dependence and maintain stable operations during outages.

When sunlight is sufficient during the day, the PV modules installed on the rooftop and canopy areas convert solar energy into electricity, and the HESP 20kW hybrid inverters convert it into AC power that can be used by the hotel. The system gives priority to supplying PV power to the hotel’s daily loads, such as guest room lighting, front desk equipment, public area lighting, network communication, and more, thereby reducing the demand for electricity purchased from the grid during the day.

When PV power generation is higher than the hotel’s real-time electricity demand, the excess electricity can be stored in the SE 48V 15kWh lithium batteries. At night, on rainy days, during typhoon weather, or during peak electricity usage periods, with 12 batteries configured for a total energy storage capacity of 180kWh, the commercial backup power supply can promptly provide power for critical loads and ensure the continuous operation of the hotel’s core equipment.
