Growatt MIC 1500TL-X2 String Inverter, 1500W, Single-Phase

The Growatt MIC 1500TL-X2 (MPN: MIC 1500TL-X2) is a compact grid-tied inverter for single-phase photovoltaic systems. With a rated AC power output of 1500 W, an MPP tracker, and a PV string input, it is suitable for appropriately sized, grid-tied PV systems. A maximum recommended PV power of 2250 W is specified for this model variant. Key technical specifications include a maximum input current of 16 A, an MPPT voltage range of 50 to 500 V, and a maximum efficiency of 97.4%. An OLED display, touchscreen controls, and flexible monitoring options round out the features.

Compact 1,500 W string inverter with 16 A PV input

• 1,500 W AC rated power for single-phase grid feed-in
• Up to 2,250 W recommended PV power
• 1 MPP tracker with 1 PV string input
• OLED display with touch button for local display and operation
• Integrated RS485; additional monitoring interfaces available
• Passive cooling via natural convection
• Integrated protection and monitoring functions

One MPP tracker for one PV string

The inverter features an MPP tracker and a PV string input. The MPP tracker (Maximum Power Point Tracker) adjusts the operating point of the connected PV string during operation so that the available solar power can be utilized within the permissible operating limits. For the MIC 1500TL-X2, Growatt specifies a maximum recommended PV power of 2,250 W.

OLED Display, Touch Controls, and Monitoring

For local operation, the MIC 1500TL-X2 features an OLED display, a touch button, and an LED status indicator. It also includes DC switches as well as connectors for PV, AC, DRM, communication, and USB. The touch button can be used to switch between display information and to select and confirm settings. The LED indicates operating states such as normal operation, warning, or error. RS485 is integrated for communication. OLED, LED, Wi-Fi, and an app are also available as display and monitoring options. These include the optional monitoring devices ShineWiFi-X, Shine4G-X, ShineLink-X, and ShineLAN-X.

Protection Features for Grid Operation

• Growatt equips the MIC-X2 series with several integrated protection and monitoring functions. These include:
• DC reverse polarity protection
• DC switch
• Type III AC/DC overvoltage protection
• Insulation resistance monitoring
• AC short-circuit protection
• Ground Fault Monitoring
• Grid monitoring
• Anti-islanding protection and residual current monitoring
• AFCI—an optional protection feature on the EU model

Anti-islanding protection prevents the inverter from maintaining an independent island grid in the event of a public grid failure. The MIC 1500TL-X2 is therefore designed for grid-connected PV operation and not for self-sufficient island operation.
