Linda Gray’s 7.63 kWp coastal installation in Luna, La Union remains a net-metered, grid-tied system with its original SMA inverter and Sunova modules. The owner is considering storage, and Solaren’s proposed approach would retain that working equipment while adding a compatible hybrid inverter and batteries. This is one of the practical considerations in choosing an inverter for a future battery retrofit: the upgrade should work with the existing installation. Battery storage remains a proposed next stage.

The coastal location influenced equipment selection because of salt exposure. The utility supported the net-metering approval process, and the system has performed in line with forecast generation since commissioning in 2024.
