String inverters remain the cost-efficient default for straightforward commercial rooftops with consistent orientation and minimal shading.
Hybrid inverters make sense wherever storage is planned now or later — retrofitting a battery onto a grid-tied-only system is usually more expensive than specifying the capability upfront.
Modular and central architectures suit larger ground-mount projects where maintenance access and redundancy outweigh the initial premium.
Whatever the architecture, confirm local voltage and frequency compliance, ambient temperature ratings, and the availability of firmware and spare parts.
