Growatt MIC 600TL-X2 String Inverter, 600W, Single-Phase

The Growatt MIC 600TL-X2 (MPN: MIC 600TL-X2) is a compact grid-tied inverter for single-phase photovoltaic systems. The inverter provides 600 W of rated AC power and features an MPP tracker with a single PV string input. With a maximum input current of 16 A, an MPPT voltage range of 50 to 500 V, and a maximum efficiency of up to 96.5%, it is designed for grid-tied conversion of solar power. Operation is via touch buttons and an OLED display; RS485 and optional monitoring interfaces, among others, are available for system communication.

Compact 600 W string inverter for single-phase PV systems

• 600 W AC rated power for single-phase grid feed-in
• Up to 900 W recommended PV power of the connected modules
• 1 MPP tracker with 1 PV string input
• OLED display with touch button for viewing and operation directly on the unit
• Integrated RS485; additional monitoring options depend on the accessories used
• IP66 protection rating against dust and high-pressure water jets
• Passive cooling via natural convection without a fan
• Comprehensive integrated protection and monitoring functions

One MPP tracker for one PV string

The string inverter operates with an MPP tracker and a PV string connected to it. The MPP tracker (Maximum Power Point Tracker) continuously adjusts the operating point of the connected solar modules so that the available PV power can be used efficiently within the permissible operating conditions. For the MIC 600TL-X2 model, Growatt specifies a maximum recommended PV power of 900 W.

600 W output power and single-phase grid injection

On the AC side, the inverter provides 600 W of rated power or 600 VA of maximum apparent power. The nominal connection is single-phase at 230 V. It is designed as a transformerless grid-tied inverter, converting the direct current from the PV modules into grid-compliant alternating current and feeding it into the connected public power grid. Battery connection as well as emergency power, backup power, or UPS functions are not specified for this model.

Operation and System Monitoring

The front panel features an OLED display, a status indicator, and a touch button. The touch interface allows users to switch between display screens and confirm settings or selections. The status indicator provides information on the current operating status and signals, among other things, normal operation, warnings, or errors. RS485 is integrated for communication. Additionally, USB, Wi-Fi, RF, and LAN can be used as available or optional interfaces. 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 built-in protection and monitoring functions. These include:
• DC reverse polarity protection
• DC switch
• Type III AC/DC surge 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 monitors the grid connection and prevents unauthorized continued operation in the event of a grid outage. This ensures that the inverter is designed for intended operation as a grid-tied PV inverter.
