Off-Grid Solar — Gau Island

This install pairs 4 × 550 W panels (TH550PMB7-46SC) with 10.24 kWh total battery storage, so the household does not just make solar power during the day, it stores some of it. Stored energy covers the evening, and when the EFL grid drops out, the battery keeps essential circuits running instead of the lights going off with the street.

The Growatt inverter (1 × SPF 5000 ES) is the hub of the system. It converts the panels' DC output into usable AC power, decides when to charge or draw from the battery, and manages the switch to backup when the grid goes down.

An exposed seaside setting makes the engineering matter more, not less. Panel layout, mounting and component placement were designed for this specific site and its conditions, the same discipline we apply to every roof we survey.

~3,410 kWh / year estimated generation. That figure comes from the engineering proposal for this specific roof and layout. Real-world output varies with weather, shading and how the household uses power, which is why we publish it as an estimate and never as a promise.

Every Solar Hub Fiji system is engineer-designed rather than picked off a shelf. Fiji's conditions reward that: strong year-round sun means high generation, but tropical heat, humidity and cyclone season put real demands on equipment and mounting.

That is why this system sits on cyclone-rated mounting engineered for high wind loads, uses tier-1 equipment backed by the manufacturer warranties listed above, and was installed by our own team with EFL paperwork handled end to end.
