Inverter Huawei 8kW SUN2000-8KTL-M1, Grid-type

The Huawei SUN2000-8KTL-M1 inverter is a three-phase grid-tie inverter with a rated power of 8 kW, designed to efficiently convert solar energy into electricity. It features two MPPT trackers that enable optimal tracking of the maximum power point, ensuring higher efficiency under different lighting conditions. The maximum input voltage is 1100 V, and the MPPT operating range is from 140 V to 980 V, making it compatible with various photovoltaic configurations.

The inverter supports a maximum input power of 12 kW and has a maximum input current of 11 A on MPPT. Its maximum efficiency reaches 98.6%, which ensures minimal energy losses during conversion. With a protection rating of IP65, the device is resistant to dust and water, 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.

Advantages of the Huawei 8kW SUN2000-8KTL-M1 inverter, Grid-type

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

The inverter supports communication via RS485, WLAN, Ethernet and optional 4G, which facilitates system monitoring and management. The wide operating temperature range of -25°C to +60°C and the ability to operate at altitudes up to 4000 m make it suitable for various climatic conditions and environments. With its high efficiency, reliability and advanced safety features, the Huawei SUN2000-8KTL-M1 is an excellent choice for grid-connected photovoltaic installations.

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: When using three-phase inverters for home use, you should know the following – three-phase inverters 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 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 batch, but single-phase consumers, you choose one of the following options:
– Transfer most large/main consumers to one of the phases and power only it 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.
