Key Specifications and Features:

- Rated Output Power (AC): It has a high rated AC output power of 2000 VA, allowing it to be paired with high-powered PV modules.

DC Input:

- Number of Inputs: 4, allowing connection to four solar panels.

- Maximum Input Current: A key differentiator, the HMS-2000D-4T has a higher maximum input current of 4 x 20 A. This makes it compatible with modern high-power PV modules (e.g., 500W+) that often have higher short-circuit currents (Isc) and operating currents (Imp).

- Maximum Input Voltage: 65 Vdc. This low-voltage DC system is a major safety feature, as it minimizes the risk of high-voltage shocks and is compliant with rapid shutdown requirements.

- MPPTs: It features four independent MPPTs. This ensures that each connected PV module operates at its maximum power point, maximizing energy harvest even with module-level shading or soiling.

- Recommended Module Power: It is designed for high-power modules, typically ranging from 400 W to over 670 W.

AC Output:

- Nominal Output Voltage: It supports both single-phase and three-phase systems, with nominal voltages of 220V/240V (single-phase) or 220V/400V (three-phase), at a frequency of 50 Hz or 60 Hz.

- High Efficiency: It maintains the high efficiency of the HMS series, with a nominal MPPT efficiency of 99.8% and a peak efficiency of around 96.50%.

Design and Durability:

- Enclosure Rating: IP67 (NEMA 6), providing full protection against dust ingress and the effects of temporary immersion in water. This makes it highly reliable for outdoor use in various weather conditions.

- Cooling: It uses a passive cooling system with no moving parts (natural convection), ensuring silent operation and a long operational lifespan.

- Operating Temperature Range: A wide range from -40°C to +65°C.

Communication and Monitoring:

- Communication: It uses a wireless Sub-1G solution for stable and reliable communication with a Hoymiles data transfer unit (DTU), such as the DTU-Pro-S or DTU-WLite-S.

- Monitoring: Integrated with the S-Miles Cloud, the system provides module-level monitoring, allowing users to track the performance of each individual panel and identify potential issues quickly.

Safety and Features:

- Rapid Shutdown Compliance: Fully compliant with rapid shutdown requirements, a critical safety feature that quickly de-energizes the DC circuits.

- Galvanically Isolated: Features galvanic isolation, providing an extra layer of safety by preventing DC current from flowing into the AC grid.

- Reactive Power Control: Supports reactive power control, helping to meet grid stability requirements.

In summary, the Hoymiles HMS-2000D-4T is a robust and intelligent microinverter, specially adapted to handle the high current of modern high-power solar panels, offering enhanced performance, safety, and module-level monitoring for advanced solar installations.
