Growatt MID 12KTL3-XH 12kW hybrid inverter with afci 3-phase

The Growatt mid 12ktl3-xh hybrid inverter is a 3-phase powerhouse that effortlessly puts large Solaranlagen into operation with its amazing performance and versatile functions. In addition to a high efficiency of 98.75%, the inverter is also characterized by its compactness and user-friendliness. This makes it a loyal partner when configuring a system. The inverter boasts 2 independent mppt inputs and can handle an impressive PV output of 24000w. For operation, it is equipped with an OLED touch display, which ensures easy and uncomplicated control. The inverter also offers the option of connecting loads and batteries. The apx battery system from Growatt is compatible with this.

Optionally, the mid-xh series can be equipped with the SYN 100 xh 30 backup boxto achieve off-grid operation.

The mid-xh series:

• 2 independent mppts
• Battery-ready, future-proof
• Type ii spd on dc and ac side
• Integrated afci function
• OLED, LED and touch button
• DC/AC ratio up to 2.0
• 24h self-consumption monitoring
• 10-year manufacturer's warranty

Hybrid inverter

In contrast to conventional inverters, hybrid inverters can not only feed the electricity generated by the Solarasystem 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 preferring to use the solar power directly in the household before it is fed into the grid.

Active safety with afci function

With an Arc Fault Circuit Interrupter is an arc fault protection device. It protects circuits in the event of arcing faults and acts as a circuit breaker against contact faults in low-voltage installations. I n addition to providing protection, it analyses current and voltage curves using digital signal processing and interrupts circuits in the event of fault signatures. afci is also known colloquially as a fire protection switch, as overheating at poor contact points or flashovers between two conductors can be prevented by emitted signals.

Two MPP trackers for optimum solar yields

Maximum Power Point Tracker technology is used to generate the best possible yield from a Solarasystem. The mppt determines the optimum ratio between irradiance, module temperature and solar cell type over the course of the day. The two MPP trackers in the mid-Inverter allow the optimum operating point for the two PV strings to be optimized separately. The two trackers work independently of each other and so, for example, shading on one string would have no effect on the second.

Operating modes - configurable according to system requirements

• Working mode: When the grid connection requirements are met - the DC voltage is greater than 200v and the grid voltage and frequency are within the permissible range, the inverter will convert the DC power generated by the solar panels into AC power and feed it into the grid with the green LED indicator. If the DC voltage drops below 160v, the inverter will automatically disconnect from the grid and exit operating mode. It will automatically return to operating mode and reconnect to the grid as soon as the requirements are met.
• Fault mode: If an unexpected situation occurs, such as a system failure or an inverter failure, the inverter will display the error message on the screen. In error mode, the leaf-shaped indicator will light up red and the inverter will be disconnected from the grid.
• Shutdown mode: If the PV power is insufficient or no PV power is generated, the inverter will automatically shut down. In shutdown mode, the inverter does not consume any energy from the grid or the solar panels and the display and indicators are switched off.

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 Solarasystems. AC spds protect the AC side and dc spds protect the DC side of the inverter. These protective devices discharge 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 arrester: type ii
• dc reverse polarity protection and disconnector
• Insulation resistance detection
• AC short-circuit protection
• Mains, residual current and string monitoring
• Stand-alone grid detection
• afci protection (arc fault detection)

Growatt monitoring platform

The Growatt monitoring platform can be used by using the optional accessories from the Shine series. This is available both 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. With Shine, you can configure and monitor all your Growatt products and view your own consumption and trends.

The following Shine options are compatible with the mid-xh series:

• Shine WiFi-X
• ShineLan-X
• ShineLink-X
