The Growatt MOD 12KTL3-HU hybrid inverter (MPN: MOD 12KTL3-HU) is a 3-phase inverter that, with its high performance and compact design, ensures simple and user-friendly operation of larger 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 24000W, the inverter also features an OLED touch display, which is a great advantage for simple and uncomplicated operation. In addition, loads and battery systems can be connected, such as Growatt's APX HV battery system.
The MOD-HU series has an integrated backup function that enables emergency power operation for important consumers without an additional backup box.
The MOD-HU series:
- 3 independent MPPTs
- Battery-ready, future-proof
- Type II SPD on DC and AC side
- Integrated AFCI function
- Support for export limitation
- OLED and touch button
- DC/AC ratio up to 2.0
- Backup function integrated as standard
Hybrid inverter
Unlike conventional inverters, hybrid inverters can not only feed the electricity generated by the solar system into the power grid, but also store it in batteries. This means that solar power is also available when the sun is not shining. Another feature of hybrid inverters is their ability to optimize a household's electricity consumption by giving priority to using solar power directly in the household before feeding it into the grid.
Active safety with AFCI function
An arc fault circuit interrupteris a fault arc protection device. It protects electrical circuits in the event of fault arcs and acts as a circuit breaker against contact faults in low-voltage installations. In addition to its protective function, it analyzes current and voltage curves using digital signal processing and interrupts electrical circuits in the event of fault signatures. Colloquially, the AFCI is also called a fire protection switch, as incoming signals can prevent fires caused by overheating at poor contact points or flashovers between two conductors.
Three MPP trackers for optimal solar yields
Maximum Power Point Tracker technology generates the best possible yield from a solar system. The MPPT determines the optimal ratio between irradiance, module temperature, and solar cell type throughout the day. The three MPP trackers in the MOD inverter allow the optimal operating point for the three PV strings to be optimized separately. The trackers operate independently of each other, meaning that shading on one string, for example, would have no effect on the others.
Operating modes – configurable depending on system requirements
- Operating mode: The MOD-HU converts the DC power from PV strings into AC power and feeds it into the power grid. As soon as the output power does not meet the requirements for grid-connected power generation, normal operating mode is switched off.
- Error mode: The inverter monitors and regulates the status of the system in real time. If, for example, system or inverter errors occur, the display shows the error information and disconnects the inverter output from the grid.
- Shutdown mode: In the event of weak or no sunlight, the inverter switches off automatically.
Integrated backup function for reliable emergency power supply
The MOD-HU series has an integrated backup output that is automatically activated in the event of a power failure. This means that important consumers can continue to be supplied with energy from the PV system and the connected battery system – without the need for an additional backup box. The switchover time is within a few milliseconds, so that the operation of sensitive devices remains largely uninterrupted. In addition, backup operation can be configured individually, e.g., to prioritize certain consumers or to maximize the battery reserve for emergency situations.
AC&DC Type II SPD
AC and DC Type II SPDs (surge protective devices) protect grid inverters from overvoltages and are an important component for the safety and reliability of solar systems. AC SPDs protect the AC side and DC SPDs protect the DC side of the inverter. These protective devices divert excess voltage pulses that can be caused by lightning strikes, switching operations in the power grid, or other events.
Numerous protective functions
- DC/AC surge arresters: Type II
- DC reverse polarity protection and disconnect switch
- Insulation resistance detection
- AC short-circuit protection
- Mains, fault current, and string monitoring
- Island network detection
- AFCI protection (arc fault detection)
Growatt monitoring platform (can be used with optional accessories)
The Growatt monitoring platform can be used with the optional accessories from the Shine series. It is available as a smartphone app (for iOS and Android) and as a web version. The Shine accessories must be purchased separately, but use of the platform is free of charge. You can configure and monitor all your Growatt products via Shine. It is also possible to display self-consumption and trends.
The following Shine options are compatible with the MOD 3-15KTL3-HU series:
- ShineWiFi-X
- Shine4G-X
- ShineLan-X
- ShineLink-X
