Inverter Huawei 4kW SUN2000-4KTL-M1, Grid-type

Inverter Huawei 4kW SUN2000-4KTL-M1, Grid-type

The Huawei SUN2000-4KTL-M1 inverter is a high-efficiency device with a rated power of 4 kW, designed for three-phase grid-connected photovoltaic systems. With a maximum efficiency of 98.6%, it ensures optimal conversion of solar energy into electricity. With an IP65 protection rating, the inverter is dust and water resistant, making it suitable for outdoor installation. Its dimensions are 525 x 470 x 146.5 mm and its weight is 17 kg, which facilitates installation and integration into various systems.

The inverter has two MPPT trackers that optimize the system performance by allowing independent control of different groups of panels. It supports communication via RS485, Wi-Fi and 4G, which allows easy monitoring and management of the system. It is also compatible with the SUN2000-450W-P optimizer, which allows the installation of more photovoltaic modules on the roof and up to 30% more energy production by optimizing each module.

Advantages of Huawei 4kW – SUN2000-4KTL-M1

One of the key advantages of this inverter is the active arc flash protection (AFCI), which significantly reduces the risk of fire and increases the safety of the system. The ability to use optimizers allows the installation of more photovoltaic modules on the roof and up to 30% more energy production through optimization of each module. The absence of wear components and the low failure rate guarantee a long service life and reliability.

Additional features and applications of Huawei 4kW inverter

The inverter supports communication via RS485, USB and Wi-Fi, which facilitates system monitoring and management. The wide operating temperature range from -25°C to +60°C and the ability to operate at altitudes up to 4,000 m make it suitable for various climatic conditions and environments. Със своята висока ефективност, надеждност и усъвършенствани функции за безопасност, Huawei SUN2000-4KTL-M1 е отличен избор за мрежови фотоволтаични инсталации.

Smart

• 2 MPP trackers for the most flexible system possible – different modules, different slopes, shaded areas, etc.
• 2 strings – intelligent monitoring and quick detection of the problem
• RS485 and USB ports for quick connection to the inverter
• Battery ready Huawei LUNA2000
• Export Limitation option (requires electricity meter) – limiting the return of excess energy to the grid
• Built-in online monitoring through the Fusion Solar platform

IMPORTANT: Three-phase systems work only and only with BALANCED phases – that is, the inverter always gives an equal amount of energy distributed over the three phases! In cases where you have a three-phase power supply, but no three-phase consumers, the following occurs – your phases are most likely not evenly loaded and have a total load of 5kW (example), but as follows:
Phase 1 Phase 2 Phase 3

3kW 1,5kW 0,5kW

But when the inverter is limiting, it reports a total consumption of 5kW from the Smart Power Sensor (electric meter) and distributes the energy as follows:

Phase 1 Phase 2 Phase 3

1,66kW 1,66kW 1,66kW

In this case, the system will have a 1.4kW shortfall on the first phase and will RETURNS 0.16kW on second phase and 1.16kW on third phase BACK to grid! There is no setting to eliminate this behavior. Therefore, we recommend that when you have a three-phase lot but single-phase consumers, you choose one of the following options:

– Transfer most large/main loads to one phase and power only that with a single phase inverter.

– You put 3 separate smaller inverters on each of the phases, with three separate meters and so they are controlled independently of each other. However, this has its disadvantage that during the least loaded phase, the inverter is idle for a large part of the time, so we recommend the above option.

Huawei provides advanced photovoltaic technology manufactured for direct use, especially in the small scale of residential, commercial and local power plants. Enables ongoing optimization from construction through operation to maintenance. The integration of digital information and Internet technology is a guarantee for optimizing initial investments, reducing operation and maintenance costs, increasing energy efficiency and a more favorable return on investment.
Huawei’s flagship product in the field of advanced residential and commercial photovoltaic technology is FusionSolar. It consists of Huawei photovoltaic converters, optimization tools, protection devices, current sensors and external communication modules. To monitor and manage the operation of the photovoltaic plant, the FusionSolar applications and the intelligent FusionSolar control system are available to the operators. The SUN2000APP application and Web UI internet software help to handle the installation and commissioning of the solar inverters and other Huawei technologies.
