Growatt MOD 12KTL3-HU 12 kW Hybrid Inverter with Integrated SYN

The Growatt MOD 12KTL3-HU hybrid inverter (MPN MOD 12KTL3-HU) is a three-phase inverter that, with its high power and compact design, ensures simple and user-friendly operation of large solar systems. The inverter features a high efficiency of 98.6%, making it a powerful and flexible device for system configuration. In addition to 3 independent MPPT inputs and a maximum PV power of 24,000 W, the inverter also includes an OLED touch display, which is highly beneficial for easy and straightforward operation. Loads and batteries can also be connected. The APX battery system is compatible for this purpose.

With this inverter, no additional SYN backup box is required for off-grid operation.

The MOD-HU series:

• 3 independent MPPTs
• Battery-ready, future-proof
• Type II SPD on DC and AC sides
• Integrated AFCI function
• Export limitation support
• OLED and touch button
• DC/AC ratio up to 2.0
• Off-grid function with integrated backup box (no additional SYN box required)

Hybrid inverter
Unlike conventional inverters, hybrid inverters can not only feed the electricity generated by the solar system into the grid but also store it in batteries. This makes solar power available even when the sun is not shining. Another feature of hybrid inverters is their ability to optimize household energy consumption by prioritizing direct use of solar power in the home before feeding it into the grid.

Active safety with AFCI function
An Arc Fault Circuit Interrupter (AFCI) is a protective device against arc faults. It protects electrical circuits from fault arcs and acts as a protective switch against contact faults in low-voltage installations. In addition to protection, it analyzes current and voltage patterns using digital signal processing and interrupts circuits when fault signatures are detected. Commonly referred to as a fire protection switch, the AFCI helps prevent fires caused by overheating at poor contact points or arcing between conductors.

Three MPP trackers for optimal solar yields
Maximum Power Point Tracker (MPPT) technology ensures the highest possible yield from a solar system. Throughout the day, the MPPT determines the optimal ratio between irradiation intensity, module temperature, and solar cell type. With two MPP trackers in the MOD inverter, the optimal operating point for three PV strings can be optimized independently. The trackers operate independently, so shading on one string does not affect the others.

Operating modes – configurable depending on system requirements

• Operating mode: The MOD-HU converts DC power from PV strings into AC power and feeds it into the grid. If the output power does not meet grid-connected generation requirements, normal operation is shut down.
• Fault mode: The inverter monitors and controls the system status in real time. If system or inverter faults occur, the display shows error information and disconnects the inverter output from the grid.
• Shutdown mode: In low or no sunlight conditions, the inverter shuts down automatically.

AC & DC Type II SPD
AC and DC Type II surge protective devices (SPDs) protect grid inverters from overvoltage and are essential for the safety and reliability of solar systems. AC SPDs protect the alternating current side, while DC SPDs protect the direct current side. These devices divert excess voltage impulses caused by lightning strikes, switching operations in the grid, or other events.

Numerous protection functions

• DC / AC surge protection: Type II
• DC reverse polarity protection and isolator
• Insulation resistance detection
• AC short-circuit protection
• Grid, residual current, and string monitoring
• Islanding detection
• AFCI protection (arc fault detection)

Growatt monitoring platform (usable with optional accessories)
With optional Shine series accessories, the Growatt monitoring platform can be used. It is available as a smartphone app (iOS and Android) and as a web version. Shine accessories must be purchased separately, but the platform itself is free to use. Through Shine, you can configure and monitor all your Growatt products, including viewing self-consumption and trends.
