Island Guesthouse Solar + Storage System — Philippines

Project Overview

Solar and battery supply for an island guesthouse with refrigeration, kitchen support loads, guest lighting, communications, and water pumping. The project was framed around a simple operating model: use solar first, reserve battery capacity for evening essentials, and retain the generator as a contingency source.

Project Challenges

• Fuel deliveries and generator maintenance created a practical operating burden for the property.
• The system needed to distinguish guest-facing essentials from discretionary loads during evening operation.

Supply Scope

• Configured a hybrid solar system with priority circuits for refrigeration, lighting, internet, water pumping, and selected kitchen equipment.
• Prepared export packing around island logistics, with clear equipment labeling and documentation for the local installation team.

Case Takeaways

• The operating concept reduces generator reliance during the solar window while retaining a defined backup path.
• Battery capacity is modular so the property can reassess expansion after recording a full guest-season load profile.

• High-efficiency PV modules
• Three-phase hybrid inverter system
• Rack-mount LiFePO4 battery storage
• Island-ready mounting, protection, and monitoring package
