Project Profile: 10kW Off-Grid Solar System Expansion – Philippines

Background

In July 2024, a homeowner in the Philippines installed a 10kW off-grid solar system with a 15kWh lithium battery to achieve energy independence. After over a year of reliable performance, the customer decided to expand the system's capacity in September 2025 to better meet their household's energy needs.

The Expansion Plan

The goal was straightforward: increase energy storage and generation to ensure uninterrupted power for longer durations. The expansion involved:

• Energy Storage: Adding a second 15kWh lithium battery.

• Power Generation: Installing 6 additional solar panels.

Final System Configuration

• Total Solar Panels: 18 panels (510W each)

• Total Battery Capacity: 30 kWh (2 x 51.2V 300Ah lithium batteries)

• Inverter: 10kW Hybrid Off-Grid Inverter

Performance & Impact

The expanded system delivers outstanding results for the household:

• Extended Backup: The combined 30kWh battery bank can now power the home's essential loads, including air conditioning, for up to five consecutive nights without any sunlight.

• Increased Daily Generation: With 18 panels, the system captures more solar energy daily, fully recharging the batteries while covering daytime consumption.

• Key Load: The system is designed to handle high-demand appliances, with the home's air conditioning unit being the largest single load.

Project Timeline

The process from order to operation is streamlined:

• Production Lead Time: 15 days

• Shipping to Philippines (Door-to-Door): Approximately 30 days

• On-site Installation: 1-2 days
