A 1% difference in inverter efficiency means hundreds of dollars over the system's lifetime. Growatt inverters achieve up to 97.5% conversion efficiency.
Monitoring
Track your system's output in real time via the Growatt ShinePhone app. See daily generation, consumption, and savings from your phone.
Safety
Built-in arc fault detection, anti-islanding protection, and surge suppression. Your inverter is the safety guardian of your entire solar system.
