Key Features:

• Maximum efficiency 98.8% (@480V)
• Ten independent maximum power point tracking (MPPT) circuits and 20 PV string inputs. Flexible configuration of PV strings is supported.
• Smart PV module self-learning: Automatically detects PV module failures, helping rectify faults. Optimises the working mode to obtain the optimal working mode of the system.
• Smart air cooling: Adjusts the fan speed based on the ambient temperature and load to ensure the service life of fans and avoid frequent maintenance.
• MBUS networking: Uses the existing power line for communication and does not require additional communications cable, which reduces the construction and maintenance costs and improves communication reliability and efficiency.
• Smart I-V curve diagnosis: Implements I-V scanning and health diagnosis for PV strings. In this way, potential risks and faults can be detected in time, improving the plant operation & maintenance (O&M) quality.
• Embedded DC and AC surge protection devices (SPDs)
• Embedded residual current monitoring unit: Immediately disconnects from the power grid upon detecting that the residual current exceeds the threshold.
• SUN2000 solar inverters apply to grid-tied systems of large-scale PV plants and commercial distributed grid-tied systems. Typically, a grid-tied PV system consists of the PV string, solar inverter, AC combiner box, and transformer station.
