More details

Installer-facing strengths:
Low start-up voltage helps the system begin producing earlier in the day.
Wide MPPT operating range gives more tolerance for module temperature changes and string layout.
Zero-export and VSG functions support sites where utility export is limited or grid-support settings are required.
IP65 protection and natural cooling reduce maintenance requirements for outdoor installations.

For a 3kW project size, it is a practical choice when the customer wants a reliable grid-tied inverter with monitoring options and no unnecessary storage hardware.
